Typhoid Fever Salmonella typhi

The video explains typhoid fever, a life-threatening illness often linked to international travel. It covers symptoms like high fever and complications if untreated. The disease is rare in developed countries but common elsewhere, affecting millions annually. Carriers can spread it without symptoms, as seen with Typhoid Mary. Caused by Salmonella typhi, the bacteria spread via the fecal-oral route, surviving stomach acid to invade intestines and cause systemic disease. Diagnosis requires lab tests, and treatment involves antibiotics. Prevention includes vaccination and careful food and water consumption when traveling.
