Typhoid, also called typhoid fever, is an illness caused by the bacterium Salmonella Typhi. The disease is spread through water which has the Salmonella Typhi bacteria in it ( transmission is by faeco oral route)
Typhoid usually lasts between two weeks and a month. The disease can be treated with antibiotics. If no treatment is given, between one and three out of every ten patients die. The rest usually get better after a month, at the most.
Typhoid causes a steady fever of at least 103-104 degrees F (39-40 degrees C). Also, it can cause stomach pains, headache, being delirious (restless, excited, seeing things), and not being hungry. In some cases, flat, pink coloured spots show up on the patient's body. Sometimes there are no symptoms.
Typhoid is not common in countries with good sanitation and clean water. For example, scientists think that there are only 400 cases a year in the United States. But around the world, there are about 21 million cases every year.[source?] For example, in the Indian subcontinent, typhoid is one of the most common diseases because of poor sanitation and lack of basic hygiene.
