What is the transmission method for typhoid fever?

• A. Airborne droplets
• B. Fecal-oral (contaminated food and water)
• C. Direct contact with infected individuals
• D. Vector-borne (insects)

Answer: (B)

Typhoid fever is primarily transmitted through the fecal-oral route, which involves the consumption of contaminated food and water. The bacteria Salmonella enterica serotype Typhi, which causes typhoid fever, is typically shed in the feces of infected individuals. If sanitary conditions are poor, this bacteria can contaminate food and water sources, leading to outbreaks. Contaminated hands may also play a significant role in the transmission, especially in areas where personal hygiene practices are inadequate. This makes proper sanitation and hygiene crucial in preventing the spread of the disease. The ability of the bacteria to survive in water and in contaminated food highlights why the fecal-oral route is the primary transmission method for typhoid fever. By understanding this transmission method, public health measures can focus on improving sanitation and encouraging practices such as proper handwashing and safe food preparation to reduce the incidence of typhoid fever.
