Typhoid fever, commonly known as typhoid is an infectious disease caused by the bacteria, Salmonella Typhi (S. Typhi). People get infected by ingestion of food or water contaminated by stool or urine of infected person.
The bacteria multiply in the digestive tract and spread into the bloodstream. In severe infections, which can be life threatening, bleeding or perforated intestine wall can happen. Without prompt treatment, it can cause serious complications and can be fatal.
After recovering from typhoid fever, a small number of people can become carriers. A carrier is a person with no symptom but continues to carry the bacteria and can potentially infect others.
