Typhoid fever is an acute illness associated with fever caused by the Salmonella enterica serotype Typhi bacteria. It can also be caused by Salmonella paratyphi, a related bacterium that usually causes a less severe illness.
Typhoid fever is rare in industrialized countries. However, it remains a serious health threat in the developing world, especially for children.
- Typhoid fever is contracted by drinking or eating the bacteria in contaminated food or water.
- People with acute illness can contaminate the surrounding water supply through stool, which contains a high concentration of the bacteria.
- Contamination of the water supply can, in turn, taint the food supply. The bacteria can survive for weeks in water or dried sewage.
