Catching diseasesChapter 6Catching diseases are those that are catching fromone individual. or animate being.

to another. The disease may be spread straight. via another species ( vector ) or via the environment. Illness will originate when the infective agent invades the host. or sometimes as a consequence of toxins produced by bacteriums in


The spread of disease through a population is determined by environmental and societal conditions which favour the infective agent. and the comparative unsusceptibility of the population. An eruption of infection could jeopardize the operation and safety of the ship. An apprehension of the disease and the steps necessary for its containment and direction is hence of import.
96THE SHIP CAPTAIN’S MEDICAL GUIDEVehicles are inanimate or inanimate agencies of transmittal of infective beings.

They include:s Water. If polluted. specifically by contaminated sewerage.

Water is the vehicle for such enteral ( enteric ) diseases as enteric fever. cholera. and amebic and bacillary dysentery. s Milk is the vehicle for diseases of cowss catching to adult male. including bovid TB. undulant fever. Milk besides serves as a growing medium for some agents of bacterial diseases such as campylobacter. a common cause of diarrhea.

s Food is the vehicle for salmonella infections ( which include enteral febrility ) . amebic dysentery. and other diarrhoeal diseases.

and poisoning. Any nutrient can move as a vehicle for infection particularly if it is natural or inadequately cooked. or improperly refrigerated after cooking. every bit good as holding been in contact with an septic beginning. The beginning may be another infected nutrient. custodies.

H2O or air.
s Air is the vehicle for the common cold. pneumonia. TB. grippe. whooping cough. rubeolas.

and varicella. Discharges from the oral cavity. nose. pharynx. or lungs take the signifier of droplets which remain suspended in the air.

from which they may be inhaled. s Dirt can be the vehicle for lockjaw. splenic fever. hookworm. and some lesion infections.

s Fomites. This term includes all inanimate objects. other than H2O.

milk. nutrient. air. and dirt. that might play a function in the transmittal of disease. Fomites include bedding.

vesture and the surfaces of objects.Vectors are animate or life vehicles which transmit infections in the undermentioned ways: s Mechanical transportation. The contaminated mouth-parts or pess of some insect vectors automatically transfer the infective beings to a bite-wound or to nutrient. For illustration. flies may convey bacillary dysentery. enteric fever.

or other enteric infections by walking over the septic fecal matters and subsequently go forthing the disease-producing sources on nutrient. s Intestinal harborage. Certain insects harbour infective ( disease doing ) beings intheir enteric piece of lands. The beings are passed in the fecal matters or are regurgitated by the vector. and the bite-wounds or nutrient are contaminated. ( e. g. pestilence.

typhus. ) s Biological transmittal. This term refers to generation of the infective agent during its stay in the organic structure of the vector. The vector takes in the being along with a blood repast but is non able to convey infection until after a definite period. during which the pathogen alterations. The parasite that causes malaria is an illustration of an being that completes the sexual phases of its life rhythm within its vector.

the mosquito. The virus of xanthous febrility besides multiplies in the organic structures of mosquitoes.Footings used in connexion with catching diseasesA bearer is a individual who has the infection. either without going ailment himself or following recovery from it.

A contact is a individual who may hold been in contact with an septic individual. The incubation period is the interval of clip that elapses between a individual being infected with any catching disease and the visual aspect of the characteristics of that disease. This period is really variable and depends upon the infective agent and the inoculant ( the sum of the infective agent ) .

The isolation period signifies the clip during which a patient enduring from an infective disease should be isolated from others.The period of communicability is the clip during which a patient who may be incubating an infective disease following contact can pass on the disease to others. The quarantine period means the clip during which port governments may necessitate a ship to be isolated from contact with the shore.

Quarantine of this sort is rarely carried out except when serious epidemic diseases. such as. for case. pestilence. cholera.

or xanthous febrility are present or have late occurred on board.Chapter 6 COMMUNICABLE DISEASESSymptoms and marksIn world it is frequently really hard to do an accurate diagnosing of an infective disease without laboratory probes. It may be possible if there are really specific characteristics such as a roseola ( chickenpox ) or bunch of implicative characteristics ( regular febrility. enlarged spleen and history of mosquito bites in an endemic country ) . Because of the trouble in doing an accurate diagnosing on board ship you may hold to give a assortment of interventions each directed at different infective agents.
OnsetAbout all catching diseases begin with the patient feeling unwell and possibly a rise in temperature. This period may be really short. enduring merely a few hours ( meningococcal sepsis ) .

or more drawn-out ( hepatitis ) . In some diseases the oncoming is mild and there is non much general perturbation of wellness. whereas in others it is terrible and bow downing. During the oncoming it is seldom possible to do a diagnosing.
The roseolaThe diagnosing of some catching diseases is made easier by the presence of a characteristic roseola. In certain diseases ( e. g. scarlet febrility ) the roseola is spread equally over the organic structure.

in others it is limited to definite countries. When analyzing an person suspected to be enduring from a catching disease. it is of great importance to deprive him wholly in order to acquire a full image of any roseola and its distribution.
General regulations for the direction of catching diseasesIsolationThe rules of isolation are described in Chapter 3 and Chapter 5. If you have a intuition that the disease with which you are covering is infective it is advisable to raise isolation safeguards every bit shortly as possible.

TreatmentAn indispensable component in intervention is keeping the patient’s good being. This is achieved through good general nursing and it is of import to guarantee that the patient does non go dehydrated.Advice on specific medical intervention for infective diseases which are likely to react to specific drugs is given under the subdivisions on intervention for the single diseases.

You may besides be advised to administrate drugs to forestall secondary infection happening. See Chapter on General Nursing and on how to cut down a high febrility.

DietDiet will really much depend on the type of disease and badness of febrility. Serious febrility is constantly accompanied by loss of appetency and this will automatically be given to curtail diet to drinks such as H2O flavoured with lemon juice and a small sugar or weak tea with a small milk and possibly sugar.
Essential BASIC regulationss Isolate. If anyone suffers from a temperature without obvious cause it is best to insulate him
until a diagnosing has been made.s Strip the patient and do a thorough scrutiny looking for any marks of a roseola in order
to seek to set up the diagnosing.

s Put him to bed. and name person to look after and nurse the patient. s Give non-alcoholic fluids in the first case.s If his temperature exceeds 39. 4C make agreements for lukewarm sponging.

9798THE SHIP CAPTAIN’S MEDICAL GUIDEs Arrange for the usage of a bed pan and urine bottle if the patient shows any mark ofcollapse or if his temperature is high.s If the patient is earnestly sick and if in any uncertainty as to the diagnosing seek RADIO MEDICAL
ADVICE. neglecting which you should see the demand for doing for port.

s Treat symptoms as they arise.Do non try to acquire the patient up during recuperation if he is lame. but keep him in bed until the following port is reached.

When nearing port. direct a wireless message giving inside informations of the instance to enable the Port Health Authority to do agreements for the isolation of the instance and any contacts on reaching and Disinfection.
Immunization and travel adviceIt is of import that up to day of the month advice on immunization and the prevalent diseases should be obtained before reaching in a foreign port.

This is most easy available from the undermentioned publications:
Health Information for Overseas Travel. produced by the UK Department of Health. and International Travel and Health.

WHO. GenevaAnthraxGallic: CharbonGerman: MilzbrandItalian: CarbonchioSpanish: CarbonIncubation Time period: 2 to 7 yearss. normally 2Time period of communicability: No grounds of transmittal from individual to individual Isolation Period: No grounds of transmittal from individual to individual Quarantine Period: None.Anthrax is an uncommon but serious catching disease which may happen in adult male and animate beings.

It occurs in adult male either as an infection of the tegument ( malignant pustule ) . or as an onslaught on the lungs or bowels. or as a widely dispersed infection throughout the organic structure by agencies of the blood circulation.

Anthrax is. in adult male.

normally contracted by managing septic animate beings. teguments. fells. or pelts. It can besides be conveyed by the ingestion of septic or insufficiently cooked meat. or by the inspiration of dust incorporating the being.

Symptoms and marksIn most instances anthrax is accompanied by terrible symptoms such as febrility and collapse. When it appears as a skin infection. it begins as a ruddy itchiness hickey which shortly changes into a blister and within the following 36 hours progresses into a big furuncle with a sheding Centre surrounded by a ring of hickeies. Alternatively it may take the signifier of a painless widespread puffiness of the tegument which shortly breaks down to organize Pus in the country.
The gastro-intestinal signifier of splenic fever resembles nutrient poisoning with diarrhea and bloody fecal matters. The lung signifier develops into a quickly fatal pneumonia.TreatmentShould a instance of splenic fever occur at sea. which is improbable unless as a consequence of managing animate beings.

fells. teguments. etc. . all dressings or other stuff that come into contact with the discharge must be burned or disposed of by disinfection.
Instruments must be used to manage dressings every bit far as possible. and the instruments must later be sterilised by vigorous boiling for non less than 30 proceedingss. since the spores of the splenic fever source are hard to kill.

Treatment is non easy on board and the patient should be put ashore every bit shortly as possible. In the interim intervention is with PenicillinNo effort at surgical intervention ( scratch or lancing of the sore ) should bemade as it does no good. Cover the sore with a dressing.Seek advice from a Port Health Authority about the intervention of lading.

Chapter 6 COMMUNICABLE DISEASESCellulitis ( Erysipelas )Gallic: ErysipeleGerman: ErysipelIncubation Period:1 to 7 yearssTime period of communicability: NoneIsolation Time period: NoneQuarantine Time period: None

Italian: ErisipelaSpanish: ErisipelaThis disease is an acute inflammatory status of the tegument caused by a source come ining the organic structure through a abrasion or scratch.

Cellulitis occurs anyplace. but most normally on the legs. weaponries and face.The oncoming is sudden with shuddering. and a general feeling of unease. The temperature rises quickly and may make about 40oC. The affected country becomes acutely inflamed and red on the first or 2nd twenty-four hours of the infection and the redness spreads quickly outwards with a well-marked.

raised. and progressing border. As the disease advances the parts of the tegument foremost attacked become less inflamed and exhibit a xanthous visual aspect. Blisters may look on the inflamed country which can be really painful.General interventionThe patient must be kept in bed during the acute phase.

Specific interventionGive the patient benzyl penicillin 600 milligram followed by unwritten antibiotic intervention. Paracetamol can be given to ease the hurting.
Chickenpox ( Varicella )Gallic: VaricelleGerman: Windpocken Italian: ChickenpoxSpanish: VaricelaIncubation Time period: 14 to 21 yearss. normally 14Time period of communicability: Up to 5 yearss before the oncoming of the roseola and 5 yearss after the first harvest of cystsIsolation Time period: Until the cysts become dryQuarantine Time period: NoneThis extremely infective disease starts with febrility and feeling unwell.

Within a twenty-four hours or two the roseola appears on the bole but shortly spreads to the face and elsewhere. even sometimes to the pharynx and roof of the mouth.

The roseola starts as ruddy hickeies which rapidly change into little blisters ( cysts ) filled with clear fluid which may go somewhat colored and gluey during the 2nd twenty-four hours.

Within a twenty-four hours or two the blisters burst or shrivel up and go covered with a chocolate-brown strikebreaker. Consecutive harvests of musca volitanss appear for up to five yearss. Although normally a mild disease. sometimes the roseola is more terrible and really seldom pneumonia may happen.TreatmentA member of the crew who has had chickenpox.

and hence has unsusceptibility. could do a suited nurse. If all of the crew have had chickenpox in the past so there is no demand to insulate the patient. The patient need non be confined to bed unless he is unwell. He should be told non to rub. particularly non to rub his face otherwise pock Markss may stay for life. Calamine lotion. if available.

dabbed onto the musca volitanss may ease the itchiness.
99100THE SHIP CAPTAIN’S MEDICAL GUIDECholeraGallic: CholeraGerman: CholeraItalian: ColeraIncubation Time period: 1 to 5 yearss. normally 2–3 yearssTime period of communicability: Normally for a few yearss after recovery Isolation Period: Until diarrhea has settledQuarantine Time period: 5 yearss

Spanish: ColeraCholera is a terrible bacterial infection of the intestine bring forthing profuse watery diarrhea. muscular spasms. purging and rapid prostration. Infection occurs chiefly through imbibing septic H2O and sometimes through feeding contaminated uncooked veggies.

fruit. blast fish or ice pick. It by and large occurs in countries where sanitation is hapless and where untreated sewerage has contaminated imbibing H2O. Other bacterial and viral causes of diarrhea can sometimes bring forth a similar clinical image and may be merely as terrible.Symptoms and marksMost instances are mild and will non be differentiated from any other signifier of diarrhea. In a terrible instance the oncoming is disconnected. the emesis and diarrhoea extreme with the fecal matters at first yellowish and subsequently pale and watery.

incorporating small white scintillas of mucous secretion resembling rice grains. The temperature is below normal. and the pulsation rapid and lame. The frequent voluminous watery fecal matters quickly produce desiccation. Vomiting is profuse. first of nutrient but shortly altering to a thin fluid similar to the H2O passed by the intestine.

Cramps of an agonizing character attack the limbs and venters. and the patient quickly passes into a province of prostration.
As the consequence of the loss of fluid. the cheeks autumn in.

the eyes become shriveled and the tegument loses its normal give and will non rapidly return to its normal form when pinched. The organic structure becomes cold and covered with a dank perspiration. the piss is bare.

the external respiration rapid and shallow. and the voice is sunk to a susurration. The patient is now ungratified.

with musculus spasms induced by loss of salt. and feebly complaining of intense thirst. This phase may quickly end in decease or every bit quickly turn to convalescence. In the latter instance the surcease of purging and purging and the return of some heat to the tegument will announce recuperation.TreatmentIf there is a suspected instance of cholera on board RADIO MEDICAL ADVICE ON MANAGEMENT SHOULD BE OBTAINED PROMPTLY.
The patient should be isolated and put to bed at one time.

Every attempt should be made to replace fluid and salt loss. Therefore. maintain a unstable balance chart. The patient should be told that his life depends on imbibing adequate and he should be encouraged and if necessary about forced to imbibe every bit much as possible until all marks of desiccation disappear ( until his urine end product is back to normal ) . Thereafter he should imbibe about 300 milliliters after each stool until the diarrhea stops. It is best to imbibe unwritten rehydration solution ( ORS ) . if this is non available. do up a solution from 20 gram of sugar with a pinch of salt and a pinch of Na hydrogen carbonate and juice from an orange in 500 milliliter unfertile H2O.

Give Doxycycline 200 milligram foremost dose so 100 milligrams one time daily. If purging. give an antiemetic tablet or injection before each dosage.

The patient must be kept in bed until seen by a physician.CautionCholera is a disease which is transmitted from individual to individual. If cholera is suspected. the ship’s H2O supply must be exhaustively treated to do certain that it is safe.

The disposal of septic fecal matters and puke must be controlled carefully since they are extremely infective. The hygiene safeguards of all attenders must be of an order to forestall them besides going infected and all nutrient readying on board must be reviewed.
Chapter 6 COMMUNICABLE DISEASESDengue febrilityGallic: DengueGerman: Denguefieber ; SiebentagefieberItalian: Dengue ; Febbra dei sette giorniSpanish: Fiebre dandy feverIncubation Time period: 3 to 14 yearss. normally 7 to 10 yearss.Time period of communicability: No individual to individual transmittal. Infective for mosquitoes for approximately 5 yearss from merely before the terminal of the feverish period.

Isolation Period: NoneQuarantine Time period: None

This is an acute febrility of about 7 days’ continuance conveyed by a mosquito. It is sometimes called break-bone febrility. It is an unpleasant.

painful disease which is seldom fatal. A terrible signifier of the disease. dandy fever haemorrhagic febrility. can happen in kids. Features of the disease are its sudden oncoming with a high febrility. terrible concern and hurting behind the orbs. and intense hurting in the articulations and musculuss. particularly in the little of the dorsum.

The face may swell up and the eyes suffuse but no roseola appears at this phase. Occasionally an antsy roseola resembling that of rubeolas but bright ruddy in coloring material appears on the 4th or 5th twenty-four hours of the unwellness. It starts on the custodies and pess from which it spreads to other parts of the organic structure. but remains most dense on the limbs. After the roseola slices. the skin prohibitionists and the surface flakes.After about the 4th twenty-four hours the febrility subsides. but it may repeat some three yearss subsequently before lessening once more by the 10th twenty-four hours.

General interventionThere is no specific intervention. but paracetamol will alleviate some of the hurting. and calamine lotion.

if available. may ease the itchiness of the roseola. Control is by remotion of Aedes mosquitoes.
DiphtheriasGallic: DiphterieGerman: DiphterieItalian: DifteriteSpanish: DifteriaIncubation Time period: 2 to 5 yearssTime period of communicability: Normally less than 2 hebdomads. shorter if the patient receives antibiotics Isolation Period: 2 hebdomadsQuarantine Time period: None

Diphtheria is an acute infective disease characterised by the formation of a membrane in the pharynx and olfactory organ. The oncoming is gradual and starts with a sore pharynx and febrility accompanied by shuddering.

The pharynx symptoms addition. get downing being painful and hard. and whitish-grey spots of membrane become seeable on the dorsum of the pharynx. the tonsils and the roof of the mouth. The spots look like wash leather and bleed on being touched.

The cervix glands crestless wave. and the breath is disgusting. The febrility may last for two hebdomads with terrible collapse. Bacterial toxins may do fatal bosom failure and musculus palsy.General interventionImmediate isolation is indispensable as diphtheria is really infective. the infection being spread by aerosols.

Specific interventionSpecific intervention is diphtheria anti-toxin which should be given at the earliest possible chance if the patient can acquire to medical attending. Antibiotic intervention should be given to all instances to restrict the spread of infection but it will non neutralize toxin which has already been produced.
101102THE SHIP CAPTAIN’S MEDICAL GUIDEEnteric febrility – enteric feverGallic: Fievre typhoideGerman: Typhus abdominalisItalian: Febbre tifoideaSpanish: Fiebre tifoideaIncubation Time period: 1 to 3 hebdomads. depending on size of infecting dose Period of communicability: Normally less than 2 hebdomads.

Drawn-out passenger car of salmonella typhi may happen in some of those non treated.

Isolation Time period: Variable.Quarantine Time period: NoneThe term enteral febrility covers typhoid and para-typhoid febrilities. Enteric febrility is contracted by imbibing H2O or eating nutrient that has been contaminated with typhoid sources. Mariners are advised to be really careful where they eat and drink when ashore. Immunisation gives sensible protection against enteric fever but non para-typhoid.

In general the para-typhoids are milder and tend to hold a shorter class. The disease may hold a broad assortment of symptoms depending on the badness of the onslaught.

Nevertheless. enteric fever febrility. nevertheless mild. is a disease which must be treated earnestly. non merely because of its possible consequence upon the patient. but besides to forestall it distributing to others who may non hold been immunised. Rigorous attending must be given to hygiene and cleanliness and all vesture and soiled linen must be disinfected.During the first hebdomad the patient feels indelicate and apathetic.

he may hold a relentless concern. hapless appetency. and sometimes nose hemorrhage. There is some abdominal uncomfortableness and normally irregularity. These symptoms addition until he is forced to travel to bed.

At this phase his temperature begins to lift in stairss making about 39–40?C in the eventides. For approximately two hebdomads it ne’er drops back to normal even in the forenoons.Any individual who is found with a relentless temperature of this sort should ever be suspected of holding enteric fever. particularly if his pulsation rate remains fundamentally normal. In 10 to 20 % of instances.

from about the 7th twenty-four hours. characteristic rose-pink musca volitanss may look on the lower thorax. venters and back.

which if pressed with the finger will vanish and return when force per unit area is released. Each topographic point lasts about 3–4 yearss and they continue to look in harvests until the terminal of the 2nd hebdomad or longer. Search for them in a good visible radiation. particularly in colored races.During the 2nd hebdomad. mental apathy. confusion and craze may happen. In the more favorable instances the patient will get down recovery but in the worst instances his status will go on to deteriorate and may end in deep coma and decease.

Even where the patient appears to be retrieving. he may endure a backsliding. There are a assortment of complications but the most unsafe are bleeding from.

or perforation of. the intestine. Where the fecal matters are found to incorporate blood at any phase of the disease the patient must be kept every bit immobile as possible and put on a milk and H2O diet. If the intestine is perforated.

peritoneal inflammation will put in.General interventionAnyone suspected of holding enteric fever or para-typhoid febrility should be kept in bed in rigorous isolation until seen by a physician. The patient’s piss and fecal matters are extremely infective. as may be his puke. These should wholly be disposed of. The attenders and others coming into the room should rinse their custodies exhaustively after managing the bedpan or rinsing the patient.

and before go forthing the room.
The patient should be encouraged to imbibe every bit much as possible and a fluid input/output chart should be maintained. He can eat every bit much as he wants.

but it is best if the nutrient is light.Specific interventionIf you suspect person has enteric fever acquire RADIO MEDICAL ADVICE. Give Cipro 500 milligram every 12 hours for one hebdomad.

On this intervention the febrility and all symptoms should react within 4–5 yearss.
All instances should be seen by a physician at the first chance. The instance notes including inside informations of the sum of medical specialty given should be sent with the patient.Chapter 6 COMMUNICABLE DISEASESGerman rubeolas – German measlesGallic: RubeoleGerman: RotelnItalian: RosoliaSpanish: RubeolaIncubation Time period: 14 to 23 yearss. normally 17Time period of communicability: For about 1 hebdomad before to at least 4 yearss after the oncoming of the rash Isolation Period: Until 7 yearss from the visual aspect of the roseola Quarantine Period: NoneGerman rubeolas is a extremely infective. though mild disease. It has characteristics similar to those of mild onslaughts of ordinary rubeolas or of vermilion febrility. For the differences in symptoms and marks see the tabular array.

Normally the first mark of the disease is a roseola of musca volitanss. though sometimes there will be concern. stiffness and tenderness of the musculuss. and some little febrility preceding or attach toing the roseola.

The roseola is absent in half the instances and stopping points from 5 to 6 yearss. The secretory organs towards the dorsum of the cervix are swollen and can easy be felt. This is an of import distinguishing mark. This swelling will predate the roseola by up to 10 yearss.General interventionGive the patient paracetamol. and calamine lotion. if available. for the roseola.

Specific interventionNote: Particular attention should be taken to insulate patients with German rubeolas from pregnant adult females: Any pregnant adult female on board should see a physician ashore every bit shortly as possible so that her unsusceptibility to rubella can be confirmed. If a patient has seen his married woman in the last hebdomad he should be asked whether his married woman might be pregnant. If so. his married woman should be advised to see her physician.
Glandular febrility – infective glandular feverGallic: Fievre glandulaire ; Mononucleose infectieuseGerman: Drusenfieber ; Infektiose MononukleoseItalian: Febbre ghiandolare ( Mononucleosi infettiva )Spanish: Fiebre glandular ( Mononucleosis infecciosa )Incubation Time period: 4 to 6 hebdomadsTime period of communicability: Prolonged. elimination of virus may prevail for atwelvemonth or more Isolation Time period: NoneQuarantine Time period: NoneThis malady is an acute infection which is most likely to impact the immature members of the crew. Convalescence may take up to two or three months.

The disease starts with a gradual addition in temperature and a sore pharynx ; a white covering frequently develops subsequently over the tonsils.

At this phase it is likely to be diagnosed as tonsillitis and treated as such. However it tends non to react to such intervention and. during this clip. a generalized expansion of secretory organs occurs.

The secretory organs of the cervix. axilla and inguens start to swell. and become stamp ; those in the cervix to a considerable extent.The patient may hold trouble in eating or get downing. His temperature may travel really high and he may sudate abundantly. Occasionally there is icterus between the fifth and 14th twenty-four hours.

Normally there is a blotched tegument roseola on the upper bole and weaponries at the terminal of the first hebdomad. Vague abdominal hurting is sometimes a characteristic. A diagnosing of diphtheria may be considered due to the visual aspect of the tonsils. but the generalized glandular expansion is typical of glandular febrility.General interventionParacetamol should be given to alleviate hurting and to chair the temperature. Any antibiotics which have been prescribed to handle the tonsillitis should be discontinued. There is no specific intervention. If complications arise acquire RADIO MEDICAL ADVICE.

103104THE SHIP CAPTAIN’S MEDICAL GUIDEHepatitis ( viral )Gallic: Hepatite: HepatitisGerman: HepatitisItalian: EpatiteSpanish: HepatitisIncubation Time period: 15 to 50 yearss for hepatitis A. 60 to 90 yearss for hepatitis B ( may be much longer )Time period of communicability: None after icterus has appeared in hepatitis A. can be indefinite for hepatitis BIsolation Time period: During first hebdomad of unwellnessQuarantine Time period: None

This is an acute infection of the liver caused by viruses. There are two chief causes of acute hepatitis: hepatitis A and hepatitis B. Two other viruses may do hepatitis ( C and E ) . but these are uncommon.

The most likely cause will be hepatitis A and this is spread by the faecal-oral path ( as is hepatitis E ) . Hepatitis B is spread sexually or by contaminated blood or acerate leafs. There is no manner of distinguishing one type of viral hepatitis from another. The piss and fecal matters will demo the typical alterations associated with icterus.TreatmentThere is no specific intervention. The patient should be put to bed and nursed in isolation.

Plenty of sugared fluids should be given until the appetite returns. When the appetency returns a nonfat diet should be given. No intoxicant should be allowed. All instances must be seen by a physician at the following port.
InfluenzaGallic: Grippe ; InfluenzaGerman: Epidemische Influenza ; GrippeItalian: InfluenzaSpanish: Influenza ; GrippeIncubation Time period: 1 to 5 yearssTime period of communicability: 3 to 5 yearss ( 7 in kids ) from the oncoming of illness Isolation Period: Frequently impractical because of the hold in diagnosing.

In an eruption it would be advisable to maintain all affected persons together and off from those who are good Quarantine Time period: none

This is an acute infective disease caused by a source inhaled through the olfactory organ or oral cavity. It frequently occurs in epidemics. The oncoming is sudden and the symptoms are. at first. the same as those of the common cold. Subsequently the patient feels much worse with tantrums of shuddering.

and terrible ache of the limbs and back. Depression. shortness of breath. palpitations. and concerns. are common. Influenza may change in badness. Normally a crisp unpleasant hectic onslaught is followed by a prompt autumn in temperature and a short recuperation.

Pneumonia is a possible complication.General interventionThe patient should be capable to standard isolation. He should be watched for marks of pneumonia such as strivings in the thorax. rapid external respiration and a blue touch to the lips. He should be given plenty to imbibe and a light and alimentary diet if he can pull off it.
Specific interventionThere is no specific intervention for the unsophisticated instance. but the patient should be given paracetamol as needed.

Chapter 6 COMMUNICABLE DISEASESMalariasGallic: PaludismeGerman: MalariaItalian: Malaria Spanish: PaludismoIncubation Time period: 12 yearss or more. depending on the type of malaria Period of communicability: The patient will stay infective for mosquitoes until they have been wholly treatedIsolation Time period: None if in mosquito-proof adjustmentQuarantine Time period: None

Malaria is a recurrent febrility caused by Protozoa introduced into the blood watercourse by the bite of the Anopheles mosquito. The malaria-carrying mosquito is most prevailing in territories where there is surface H2O on which it lays its eggs.

It is a unsafe tropical disease which causes febrility. infirmity and. sometimes. coma and decease.Malarial countriesPorts between latitudes 25?N and 25?S on the seashores of Africa ( including Malagassy ) . Asia.

and Central and South America should be regarded as septic or potentially infected with malaria. Questions should be made anterior to departure to let appropriate prophylaxis to be arranged and intervention drugs obtained. Before reaching in port farther questions should be made as to the current malaria state of affairs and prophylaxis issued to the crew if necessary.

Prevention of malariaThe hazards of onslaughts of malaria can be really greatly reduced if proper safeguards are taken and the disease can be cured if proper intervention is given. Despite this. instances have occurred in ships where several members of the crew have been attacked by malaria during a individual ocean trip with terrible and even fatal consequences.

The safeguards are:s turning away of mosquito bites ;s bar of infection.

Avoidance of mosquito bitesThe best manner to forestall malarial infection is to take steps to avoid being bitten. The coming of air conditioned ships has made many traditional preventative steps obsolete. However. when within two stat mis of a malarial shore it remains of import that: s doors are kept closed at all times after twilight ;
s any mosquitoes which enter compartments are killed utilizing insecticide spray ; s individuals traveling on deck or ashore after twilight wear long sleeved shirts and pants to avoidexposing their weaponries and legs ;s no pools of dead H2O are allowed to develop on deck or in life boats. where
mosquitoes might engender.In ships which are non air conditioned other traditional steps to protect against mosquitoes should be implemented.

These include:s puting all right wire mesh over portholes. sky visible radiations. ventilators and other gaps ; s testing visible radiations to avoid pulling mosquitoes ;s repairing mosquito cyberspaces over beds where adjustment infinites can non be made mosquito

cogent evidence.Prevention of infectionThe fewer the bites.

the smaller is the hazard of infection but even when the greatest attention is exercised it will rarely be possible wholly to forestall mosquito bites either on shore or in the
105106THE SHIP CAPTAIN’S MEDICAL GUIDEship. For this ground in all instances when a ship is bound for a malarial port. Masters ( in add-on to taking all possible steps to forestall mosquito bites ) should command infection by giving intervention consistently to all the ship’s crew.Preventive intervention ( prophylaxis ) does non ever forestall a individual from undertaking malarial infection. but it will cut down the opportunity of disease.

All individuals. hence. should be warned that they have been exposed to the opportunity of malaria infection and that. if they fall badly at a ulterior day of the month. they should inform their physician without hold that the febrility from which they are so enduring may be due to malaria contracted abroad.

The most appropriate prophylaxis will change with the location as there are different types of malaria in assorted parts of the universe. There is besides increasing opposition to anti-malarials which will impact their effectivity. Up to day of the month information should be obtained before going if possible or from thelocal wellness governments.
General guidelinesStart taking the prophylaxis before reaching at a malarial country in conformity with specific instructions and depending on the part. ( Normally 1-3 hebdomads before going ) . This will let the tolerance and side-effects ( if any ) of the contraceptive drug to be assessed. Prophylaxis should be continued for 4 hebdomads after go forthing the malarial country so as to guarantee all phases of the parasite have been killed.

No drugs for the intervention of malaria are specified in the MSN 1726 as the advice varies with finish and the form of disease in any given malarial country at the clip. For information. the UK’s present guidelines recommend 3 different governments depending on finish:s Proguanil 200 milligram one time day-to-day and chloroquine 300 mg hebdomadals Mefloquine 250 milligram one time hebdomadals Maloprim ( a combined tablet of dapsone and pyrimethamine ) 1 tablet hebdomadal and

chloroquine 300 mg hebdomadalOther governments may be used in countries of high degree opposition
Treatment of malariaFeatures of the unwellnessMalarias can non be diagnosed with certainty without laboratory aid.

If the individual has been in a potentially malarial country within the last few months and has a febrility they should be assumed to hold malaria. The characteristic forms of febrility associated with malaria ( fever every 2 to 3 yearss ) may non be obvious. The unwellness may come on quickly without many characteristics other than febrility and perspiration. There will frequently be a terrible concern. If there is any uncertainty about whether to handle or non acquire RADIO MEDICAL ADVICE.

General intervention for mild or terrible malariaThe patient should be put to bed in a cool topographic point and his temperature. pulsation and respiration taken four hourly.

If body temperature rises to 40oC or over. chilling should be carried out. The temperature should be taken and recorded at 15 minute intervals until it has been normal for some clip. Thereafter the four-hourly recording should be resumed until the onslaught has decidedly passed.
Specific intervention for mild or terrible malariaAnti-malarial drugs are non specified in MSN 1726 as intervention depends on the country and forms of opposition.

If anti-malarials are to be carried seek appropriate advice on which to obtain/use.The undermentioned illustrations of current governments are given for information: s Quinine 600 milligram every 8 hours for 7 yearss followed by Fansidar ( see below ) 3 tablets as a

individual dosageors Mefloquine 500 milligram ( 2 tablets ) for 2 doses 8 hours apart

Chapter 6 COMMUNICABLE DISEASESChloroquine is non used for intervention except for proved individual infections with vivax and other benign malarias because of drug opposition. If quinine. Fansidar or Larium are non available so chloroquine 300 milligram 8 hourly for three doses so 300 milligrams daily for 2 yearss should be used.If the patient is unable to take medical specialty by oral cavity or is purging so quinine 600 milligram should be given by intramuscular injection every 8 hours. Equally shortly as the patient is able to get down it should be given by oral cavity. Quinine may bring forth pealing in the ears or giddiness. but this should non usually be a ground to halt intervention.Note: All patients who have been treated for malaria or suspected malaria must see a physician at the following port because farther medical intervention may be necessary.MeaslessGallic: Rougeole
German: MasernItalian: MorbilloSpanish: SarampionIncubation Time period: 7 to 18 yearss normally 10 until oncoming of febrility. 14 yearss until rash Period of communicability: approximately 10 yearss. minimally infective after the 2nd twenty-four hours of the rash Isolation Period: 4 yearss after oncoming of roseolaQuarantine Time period: NoneMeasless does non frequently occur in grownups. See besides the subdivisions on German rubeolas and vermilion febrility and the tabular array of differences of symptoms.The disease starts like a cold in the caput. with sneezing. a running olfactory organ and eyes. concern. cough and a little febrility 37. 5?C–39?C. During the following two yearss the catarrh extends to the pharynx doing gruffness and a cough. A careful scrutiny of the oral cavity during this period may uncover minute white or blue white musca volitanss the size of a pin’s caput on the interior side of the cheeks. or the lingua and interior side of the lips. These are known a ‘Koplik spots’ and are non found in German rubeolas and vermilion febrility.

The roseola appears on the 4th twenty-four hours when the temperature increases to 39–40?C. Pale rose-coloured musca volitanss foremost appear on the face and spread down to cover the remainder of the organic structure. The musca volitanss run together to organize a dappled blotchy visual aspect. The roseola deepens in coloring material as it gets older. In four or five yearss the roseola begins to melt. get downing where it foremost appeared. The tegument may skin. The chief danger of rubeolas is that the patient may acquire bronchitis. pneumonia or in-between ear infection.General interventionThis extremely infective disease is conveyed to others when the patient coughsor sneezing. There is no specific intervention. but the patient may hold paracetamol. Calamine lotion. if available. may be applied to comfort the roseola.

Meningococcal disease ( meningitis and blood poisoning )Gallic: Meningite cerebro-spinal epidemiqueGerman: Epidemische Meningitis Cerebro-spinalItalian: Meningite cerebro-spinal epidemicaSpanish: Meningitis cerebro-spinal epidemicaIncubation Time period: 2 to 10 yearss. normally 3 to 4Time period of communicability: By and large non catching whilst the patient is on antibiotics Isolation Period: For 24 hours after the start of antibiotics Quarantine Time period: NoneInfection caused by the meningococcus ( a bacteria ) can do either meningitis. with redness of the membranes environing the encephalon and spinal cord. or a blood poisoning characterised by a generalized roseola that does non melt on force per unit area. Unless treated quickly and efficaciously. the result is about ever fatal. It occurs in epidemics which may impact closed communities such as a ship. The infection enters by the nose and oral cavity. Meningitis starts all of a sudden with febrility. considerable concern and emesis. Within the first twenty-four hours the temperature increases quickly to 39?C or more and the concern becomes agonizing.

107108THE SHIP CAPTAIN’S MEDICAL GUIDEVomiting additions and there is general backache with hurting and stiffness in the cervix. Intolerance of visible radiation ( photophobia ) is normally present. The patient may be intensely cranky and resent all intervention. or may even be hallucinating.As the meningitis develops the patient adopts a characteristic position inbed. lying on the side with his dorsum to the visible radiation. articulatio genuss drawn up and make out set backwards. Unconsciousness with incontinency may develop.
The blood poisoning caused by the meningococcus besides starts all of a sudden with a grippe like unwellness. A roseola develops rapidly. get downing with pin asshole like musca volitanss which will non blanche when pressed. This roseola may come on to organize big dark ruddy countries.Individual instances may change in the velocity of oncoming. the badness of the unwellness and the clinical characteristics which are present.If meningitis is suspected get RADIO MEDICAL ADVICE and it will assist the physician if the consequences of the two followers trials are available:
The cervix flexing trialAsk the patient to try to set his mentum on his thorax. In meningitis the patient will be unable to make so because forward cervix motion will be greatly restricted by musculus contraction. Try to increase the scope of forward motion by forcing gently on the dorsum of his caput. The cervix musculuss will contract even more to forestall the motion and the concern and backache will be increased.
The articulatio genus unbending trial– Figure 6. 1A. Bend one leg until the heel isnear to the cheek.

( A ) Bend one leg until the heelis near to the cheek.

Until such advice is received. give benzyl penicillin 2. 4 g at six hourly intervals. The concern should be treated with codeine. The patient should come under the attention of a physician every bit shortly as possible.
Chapter 6 COMMUNICABLE DISEASESMumpssGallic: OreillonsItalian: Malaria Orecchioni

German: Mumps – ZiegenpeterSpanish: Orejones
Incubation Time period: 12 to 26 yearss. normally 18Time period of communicability: 7 yearss before glandular puffiness and up to 9 yearss after Isolation Period: 9 yearss after swelling startedQuarantine Time period: NoneMumps is a viral disease which causes the puffiness of the salivary secretory organs in forepart of the ears and around the angle of the jaw. The swelling normally affects both sides of the face though it may merely impact one side and it may do the oral cavity hard to open. The oncoming is normally sudden and may be accompanied by a little febrility. The swelling bit by bit diminishes and should vanish wholly in approximately 3 hebdomads.

Approximately 20 % of work forces with epidemic parotitiss get orchitis which is the swelling of one or both testiss ; when this occurs it normally happens around the 10th twenty-four hours. Whilst really painful. orchitis does non normally result in sterility and ne’er in powerlessness.General interventionThe patient should be put in standard isolation for 9 yearss and remain in bed for 4 to 5 yearss or until the febrility is no longer present. He can be given paracetamol to alleviate the symptoms. but there is no specific intervention.
If he develops conceited painful testiss ( orchitis ) he should remain in bed. He should back up the scrotum on a tablet or little pillow. The testiss should besides be supported if the patient gets up for any ground.PlagueGallic: Peste
German: PestItalian: PesteSpanish: PesteIncubation Time period: 2 to 6 yearssTime period of communicability: Equally long as infected fleas are present. Person to individual spread is uncommon except with pestilence pneumonia.Isolation Time period: For 3 yearss after the start of antibiotic intervention Quarantine Period: 6 yearssPlague is a serious bacterial disease transmitted to adult male by septic rat fleas. It may show in three waysBubonic in which buboes ( conceited lymph nodes ) are the most obvious characteristic. The nodes are painful and may seep Pus.Pneumonic in which pneumonia is the chief characteristic. The type of pestilence is really infective as the phlegm contains the pestilence bacteria.Septicaemic which is quickly fatal.The onslaught begins all of a sudden with terrible unease. shuddering. strivings in the dorsum and sometimes purging. The patient becomes prostrated and is confused. His temperature reaches about oC C and the pulsation is rapid. After about 2 yearss the buboes may develop. most normally in 38

the inguens. The buboes may soften into abscesses.General interventionThe patient should be cared for by an attender who should have on a face mask to cover his nose and mouth The patient should be isolated and taken every bit shortly as possible to a port where he can be treated. He should rest in bed. be encouraged to imbibe as much fluid as possible and have a really light diet. If the abscesses burst they should be dressed with a simple dressing. but they must non be lanced. Soiled linen and bed apparels should be boiled for 10 proceedingss or destroyed.
109110THE SHIP CAPTAIN’S MEDICAL GUIDESpecific interventionGive Doxycycline 100 milligram one time day-to-day for at least 5 yearss. The patient should stay on complete bed remainder during recuperation.
PreventionPlague should be notified to the local wellness governments at the following port of call. The quarters of the patient and the crew should be treated with insecticide pulverization and dust to guarantee the devastation of fleas.
WarningDead rats should be picked up with tongs. placed in a fictile bag. which should be sealed with twine. leaden and thrown overboard ; if the ship is in port. the dead rats should be disposed of in the mode required by the port medical wellness authorization.
Poliomyelitis – childish palsyGallic: PoliomyeliteItalian: Poliomielite

German: PoliomyelitisSpanish: Poliomielitis
Incubation Time period: 3–21 yearss. normally 7–14 yearssTime period of communicability: Cases are most infective during the first few yearss before and after the oncoming of symptomsIsolation Time period: Not more than 7 yearssQuarantine Period NonePoliomyelitis is an acute viral disease that occurs largely in kids. It isa disease about wholly preventable by immunization.The badness ranges from non-apparent infection to non-specific feverish unwellness. meningitis. paralytic disease and decease. Symptoms of the mild disease include febrility. unease. concern. sickness and emesis. If the disease progresses. terrible musculus hurting and stiffness of the cervix and back. with or without palsy will happen. The most normally affected parts are the legs and weaponries. shoulders. stop and thorax musculuss. The development of palsy is by and large complete within two yearss and so recovery begins. The recovery may be complete or go forth some grade of palsy

Affected musculuss are normally painful and stamp if touched. They are ever limp and motions of the affected parts are either weakened or lost by the cachexia which appears really shortly after palsy.Paralysis of the respiratory musculuss may do shortness of breath and blueness of the lips.General interventionThere is no specific intervention but much can be achieved by good nursing. The patient should hold complete remainder in bed. Pain should be treated with paracetamol and/or codeine. If a limb has been affected it should be supported by pillows in such a manner that the paralysed musculuss can non be stretched. The articulations above and below the palsy should be put through a full scope of motion forenoon and eventide to forestall stiffness. In all instances. every bit shortly as palsy appears. RADIO MEDICAL ADVICE must be sought. If the respiratory musculuss are affected. take a breathing trouble may result. Pressing stairss must be taken to acquire the patient to skilled hospital intervention every bit shortly as possible.
Chapter 6 COMMUNICABLE DISEASESRabiess – hydrophobiaGallic: La ramp
German: TollwutItalian: RabbiaSpanish: RabiaIncubation Time period: in worlds the incubation period is normally 2 to 12 hebdomads. shortest for patients bitten about the caput and those with extended bites Communicability: Rabies is seldom. if of all time. spread from human to human. Nevertheless for the continuance of the illness taint with spit should be avoided by have oning baseball mitts when nursing the patientIsolation Time period: Duration of the unwellnessQuarantine Time period:Rabiess is an acute infective viral disease that is about ever fatal. When a rabid mammal bites worlds or other animate beings. its saliva transmits the infection into the lesion. from where it spreads to the cardinal nervous system. Rabies is chiefly an infection of wild animate beings such as rotters. prairie wolfs. foxes. wolves. raccoons. chiropterans. squirrels. coneies. and chipmunks. The most common domestic animate beings reported to hold hydrophobias are Canis familiariss. cats. cowss. Equus caballuss. mules. sheep. caprine animals. and swine. It is possible for hydrophobias to be transmitted if morbific spit enters a abrasion or fresh interruption in the tegument.

The development of the disease in a bitten individual can be prevented by immediate and proper intervention. Once symptoms of hydrophobias develop. decease is virtually certain to ensue. Thus bar of this disease is of the extreme importance.Local port governments should be informed of possible rabid animate beings. so that appropriate public wellness steps can be instituted.TreatmentEqually shortly as an single aboard ship Is known to hold been bitten by a Canis familiaris or other perchance rabid animate being. RADIO MEDICAL ADVICE should he obtained at one time. Normally suspected instances are sent ashore to obtain the expert interventionand nursing attention needed to forestall the disease.

Immediate local attention should be given. Vigorous intervention to take hydrophobias virus from the bites or other exposures to the animal’s spit may be every bit of import as specific anti-rabies intervention. Free hemorrhage from the lesion should be encouraged. Other local attention should dwell of:s thorough irrigation of the lesions with soap or detergent H2O solution ; s cleansing with antiseptic solution ;s if recommended by wireless. giving an antibiotic to forestall infection: s administrating adsorbed lockjaw anatoxin. if indicated.s Suturing of bite lesions should be avoided.

PreventionWhen abroad. mariners should maintain away from warm-blooded animate beings particularly cats. Canis familiariss. and other carnivores. It is strongly advised that pets should non be carried on board ship as these may go septic unnoticed. through contact with rabid animate beings in ports.
111112THE SHIP CAPTAIN’S MEDICAL GUIDEScarlet febrilityGallic: Scarlatine
German: ScharlachItalian: ScarlattinaSpanish: EscarlatinaIncubation Time period: 1 to 3 yearssTime period of communicability: 3 yearssIsolation Time period: 14 yearss in untreated instances. 1 to 2 yearss if given antibiotics. Quarantine Time period: NoneScarlet febrility is non frequently contracted by grownups. It has characteristics similar to those of rubeolas and German rubeolas ; see the tabular array of differences of symptoms.

The oncoming is by and large sudden and the temperature may quickly lift to 39. 5 to 40?C on the first twenty-four hours. With the febrility the other chief early symptom is a sore pharynx. which in most instances is really terrible. The tegument is hot and firing to the touch. The roseola appears on the 2nd twenty-four hours and consists of bantam bright ruddy musca volitanss so near together that the tegument assumes a vermilion or boiled lobster-like coloring material. It normally appears first on the cervix. really quickly spreads to the upper portion of the thorax and so to the remainder of the organic structure. There may be an country around the oral cavity which is clear of the roseola.The lingua at first is covered with white pelt and. when this goes. it becomes a really bright ruddy ( strawberry ) . The high febrility normally lasts about a hebdomad. As the roseola fades the tegument Peels in round spots. The danger of vermilion febrility arises from the complications associated with it. e. g. redness of the kidneys ( prove the piss for protein one time a twenty-four hours ) . redness of the ear due to the spread of infection from the pharynx. rheumatism and bosom disease. These complications can be avoided by careful intervention.General interventionThe patient must remain in bed and be kept every bit quiet as possible. The patient can be given paracetamol to alleviate the hurting in the pharynx which may besides be helped if he takes plentifulness of cold drinks. He can take such nutrient as he wishes.
Specific interventionAs vermilion febrility normally follows from a sore pharynx or tonsillitis you may already be giving him the relevant intervention. Otherwise give the specific intervention for tonsillitis.
Tetanus – tetanusGallic: Tetanos
German: WundstarrkrampfItalian: TetanoSpanish: TetanosIncubation Time period: 4 to 21 yearssTime period of communicability: No individual to individual transmittalIsolation Time period: NoneQuarantine Time period: NoneTetanus is caused by the infection of a lesion by the lockjaw bacteria which secretes a powerful toxicant ( toxin ) . This bacteria is really widespread in nature and the beginning of the wound infection may non ever be easy to follow. Puncture lesions are peculiarly apt to be unsafe and overlooked as a point of entry. In the UK immunization against the disease normally begins in childhood but it is necessary to hold farther periodic vaccinations to keep effectual unsusceptibility. Fortunately the disease is a really rare status on board ship. The first marks of the disease may be cramps or stiffening of the jaw musculuss and. sometimes. other musculuss of the face taking to difficulty in opening the oral cavity and swallowing. The spasms tend to go more frequent and spread to the cervix and back doing the patient’s organic structure to go arched.

The patient remains to the full witting during the cramps which are highly painful and brought on by external stimulation such as touch. noise or bright visible radiation. The patient is increasingly exhausted until bosom and lung failure prove fatal. Alternatively. the contractions may go less frequent and the patient recovers. but there is a high mortality.TreatmentThe patient should be isolated in a darkened room every bit far as possible from all perturbations. Get RADIO MEDICAL ADVICE. Give antibiotic intervention and give Valium or Thorazine as sedation and to command cramp. The patient must be got to hospital every bit shortly as possible.

This infective disease is caused by the tubercle B. Although the lung ( pneumonic ) disease is the most common. TB bacterium may assail other tissues in the organic structure: castanetss. articulations. secretory organs. or kidneys. Unlike most contagious diseases. TB normally takes a considerable clip to develop. frequently looking merely after repeated. stopping point. and drawn-out exposures to a patient with the active disease. A healthy organic structure is normally able to command the tubercle B unless the invasion is overpowering or opposition is low because of chronic alcohol addiction. hapless nutrition. or some other debilitative status.The pneumonic signifier of the disease is dispersed most frequently by coughing and sneezing. A individual may hold TB for a long clip before it is detected. Symptoms may dwell of nil more than a relentless cough. lit
