How is filariasis primarily transmitted according to nursing knowledge?

• A. Via contaminated food
• B. Through direct contact with infected individuals
• C. By being bitten by an insect that contained worm embryos
• D. Through exposure to contaminated water

Answer: (C)

Filariasis is primarily transmitted through the bite of specific species of mosquitoes that carry the larval form of the filarial worms. When an infected mosquito bites a human, it injects the larvae into the bloodstream, where they can develop into adult worms and cause various health issues related to the filarial infection. This mode of transmission highlights the vector-borne nature of filariasis, which distinguishes it from other transmission routes like those involving contaminated food, water, or direct contact between individuals. Understanding this transmission pathway is integral to devising effective prevention strategies, such as mosquito control and awareness in endemic areas.
