Which disease caused by nematode worms is transmitted by the bite of a mosquito?

Filariasis is caused by nematode worms and is transmitted through the bite of infected mosquitoes. The main culprits are various species of filarial worms, such as Wuchereria bancrofti, Brugia malayi, and Loa loa, which can lead to conditions like lymphatic filariasis and river blindness. Mosquitoes serve as vectors in the life cycle of these parasites, allowing them to pass from one host to another.

Dengue fever and malaria are also transmitted by mosquitoes, but they are due to viruses and protozoa, respectively. While psittacosis involves infections but is associated with birds rather than transmission via mosquitoes, confirming filariasis as the correct answer highlights the specific relationship between nematodes and their mosquito vectors in the context of human disease.
