Salmonella Typhi is a type of bacteria that causes typhoid fever, a serious illness primarily found in developing countries. It spreads through contaminated food and water, often due to poor sanitation practices. Symptoms include high fever, weakness, stomach pain, and diarrhea.
Once ingested, Salmonella Typhi can invade the bloodstream, leading to severe complications if untreated. Diagnosis typically involves blood tests, and treatment usually requires antibiotics. Vaccines are available to help prevent typhoid fever, especially for travelers to areas where the disease is common.
