Enteric fever, commonly known as typhoid fever or paratyphoid fever, is a serious illness caused by the bacteria Salmonella typhi and Salmonella paratyphi. It is primarily transmitted through contaminated food and water, leading to symptoms such as prolonged fever, abdominal pain, and diarrhea. The disease is more prevalent in areas with poor sanitation and limited access to clean water. Vaccines are available to help prevent typhoid fever, and proper hygiene practices, such as handwashing and safe food preparation, are essential in reducing the risk of infection.
