Typhoid fever is an infectious disease caused by the bacteria Salmonella typhi. It is also known as enteric fever, or commonly just typhoid. It easily spreads through contaminated food and water supplies and close contact with others who are infected. The illness is characterized by very high fever, sweating, gastroenteritis, and diarrhea. Although typhoid is very rare in the developed world, it is still a serious health threat in the developing world.

How the infection spreads
The Salmonella typhi bacteria will be in the stools (poo) of an infected person after they've been to the toilet. If they don't wash their hands properly afterwards, they can contaminate any food they touch. Anyone else who eats this food may also become infected.
Less commonly, the Salmonella typhi bacteria can be passed out in an infected person's urine. Again, if an infected person handles food without washing their hands properly after urinating, they can spread the infection to someone else who eats the contaminated food.
In parts of the world with poor sanitation, infected human waste can contaminate the water supply. People who drink contaminated water or eat food washed in contaminated water can develop typhoid fever.

Other ways typhoid fever can be contracted include:
+ using a toilet contaminated with bacteria and touching your mouth before washing your hands
+ eating seafood from a water source contaminated by infected faeces or urine
+ eating raw vegetables that have been fertilized with human waste
+ contaminated milk products
+having oral or anal sex with a person who's a carrier of Salmonella typhi bacteria

Symptoms
It usually takes 1 to 3 weeks time for patients to develop typhoid symptoms after exposure to the bacteria. The duration of the disease is 3 to 4 weeks depending upon the severity of the disease (mild or severe) with the normal incubation time is 7 to 14 days. The symptoms are –
Headaches
Constipation or diarrhea
High fever (103 degree F)
Lethargy
Poor appetite
Enlarged spleen & liver
Rose-colored spots on the chest
Chest congestion
Abdominal pain
Fatigue
Chills
Generalized pain and weakness.
(The difference between Malaria & Typhoid is that in Typhoid the pulse get slower as the fever goes up.In malaria the pulse increases and the fever increases)

Complications of typhoid fever
Complications caused by typhoid fever usually only occur in people who haven't been treated with appropriate antibiotics or who weren't treated straight away.

In such cases, about 1 in 10 people experience complications, which usually develop during the third week of infection.
The two most common complications in untreated typhoid fever are:
internal bleeding in the digestive system
splitting (perforation) of a section of the digestive system or bowel, which spreads the infection to nearby tissue
