Question

Lymphatic filariasis is spread by

• A. Mosquitoes
• B. Parasitic worms
• C. Parasitic Bacteria
• D. Viruses

Answer 1

The correct option is A Mosquitoes

The vector for spreading the parasite, Wuchereria bancrofti - the causative agent of lymphatic filariasis, is mosquito. When a mosquito bites an infected person, it takes in the microfilariae of the parasitic worms, and transfers it to a healthy person during the next blood meal. Thus the infective cycle continues and disease spreads from one person to another.
