Which disease is listed as transmitted by the house fly?

• A. Malaria
• B. Dengue
• C. Anthrax
• D. Sleeping sickness

Answer: (C)

The main concept here is that house flies can spread disease as mechanical vectors. They pick up pathogens from contaminated material and transfer them to food or surfaces they land on, without the pathogen needing to develop inside the fly. Bacillus anthracis spores, which cause Anthrax, are known to survive in the environment and can hitch a ride on flies, then be deposited onto feed, crops, or other surfaces, enabling exposure. Malaria and dengue pathogens are transmitted by specific mosquitoes (Anopheles for malaria, Aedes for dengue), not by house flies, and sleeping sickness is spread by the tsetse fly. Those insects are not the vectors associated with house flies in disease transmission.
