Typhoid is an infection caused by the bacterium S. typhi.
The bacterium lives in the intestines and bloodstream of humans. It spreads between individuals through direct contact with the feces of a person with an infection.
No animals carry this disease, so transmission is always from human to human. S. typhi enters through the mouth and spends 1–3 weeksTrusted Source in the intestine. Then, it makes its way through the intestinal wall and into the bloodstream.
From the bloodstream, it spreads into other tissues and organs. The immune system of the host can do little to fight back, because S. typhi can live within the host’s cells, safe from the immune system.
Doctors diagnose typhoid by detecting the presence of S. typhi via blood, stool, urine, or bone marrow sample.
Causes:
Typhoid is caused by the bacteria S. typhi.
It spreads through food, drinks, and drinking water that are contaminated with infected fecal matter. Washing fruit and vegetables can spread it as well if the water is contaminated.
