Typhoid fever can be transmitted by the

• A. Air
• B. Water
• C. Food
• D. Fly

Answer: (D)

Typhoid fever spreads mainly through the fecal-oral route, with contaminated water and foods acting as common vehicles. A fly can pick up Salmonella Typhi from fecal matter and transfer it to food or surfaces, making it a mechanical vector that can facilitate transmission. Because the question focuses on a concrete vector that can transfer the bacteria between sources, the fly stands out as a relevant transmission route. Air is not a typical pathway for typhoid, and while water and food are vehicles, identifying a vector like a fly highlights how insects can spread contamination in real-world settings. Controlling flies and ensuring safe water and food handling are important precautions to reduce transmission.
