Typhoid fever is an acute, infectious disease caused by the Salmonella typhi bacteria, which is often transmitted through contaminated food or water. Common symptoms include sustained high fever, headaches, stomach pains, and fatigue. The disease is most often spread when people consume food or water contaminated with Salmonella from the feces of infected individuals. Prevention methods focus on vaccination, proper hygiene, and controlling transmission through public education and monitoring infected individuals and their contacts.
