Typhoid fever is an illness caused by the bacterium Salmonella Typhi (S. Typhi). It infects your small intestines (gut) and causes high fever, stomach pain and other symptoms. Typhoid fever is also called enteric fever.
You’ll commonly hear paratyphoid fever mentioned along with typhoid. Paratyphoid fever is similar to typhoid with more mild symptoms. It’s caused by Salmonella Paratyphi (S. Paratyphi).
S. Typhi and S. Paratyphi are different than the Salmonella bacteria that cause salmonellosis, a common type of food poisoning.
