Mode of Transmission:
The Typhoid bacilli are present in large number in the urine and stools of the patient. It is conveyed to head the persons in food or water, contaminated by it. The bacilli are also present in the intestine, gall bladder an urinary organs of the persons, those who have recovered from the disease and may contaminate food or drink by handling it, the fly plays an important part in spreading the infection.

The disease is prevalent in all the countries the world but is more common where sanitary arrangement as regards water supply and disposal of sewage are not satisfaction factory. One attack, as a rule, gives immunity for life- Incubation Period:
The incubation period of typhoid fever is 14 but in some cases may be as short as 5 and as long as 21 days.
The onset of the disease is gradual and the patient does not feel sufficiently ill for the first 4 to 5 days. A dull headache, lassitude, incapacity for much physical or mental work, loss of appetite and aching of the limbs and back are present from the beginning which slowly increase and compel the patient to take to bed. In some cases, there is bleeding from the nose.
The temperature shows a rise of 1 to 2 degrees in the evening and a slight fall in the morning and it reaches 103 or 104 degrees in a week’s time and remains for some days. Constipation which is present in the beginning gives place to diarrhea. The stools are watery, grayish brown in color and called “Pea-soup” stools of typhoid. The pulse rate becomes low being about 100 per minute. Sudden rise in pulse rate will indicate the onset of some Complication such as bleeding from the bowels, pneumonia etc.
The tongue becomes dry and coated with a thick layer of dark fur in the middle, leaving the sides and the tip which are clear and pink red in color. The spleen gets enlarged and the abdomen distended and tender on pressure. By the time these symptoms are fully developed and the patient passes in to a state of prostration known as the Typhoid state.
Profound nervous depression is seen, which are tremors of the tongue, hesitating speech, twitching of muscles and passing of the stool and urine in the bed. Sleeplessness is present from the beginning and is very troublesome.
However, the typhoid fever does not always run the typical course described above. Instead of a gradual on set it may come on suddenly with chills and fever which does not follow the usual course. In infants and young children the early symptoms are vomiting, diarrhea or convulsions. In older children the disease usually runs a mild course. Prevention:

The mouth and coated tongue should be cleaned several times during the day, particularly before feeding. At the time of rise of high temperature cold sponging, ice cap and head washing should be done. Chloromycetin is the drug of choice it is found to shorten the duration of the disease and prevents complications. It should be continued in a milder dose for a week, after the temperature is normal, as otherwise relapse is likely to take place.
