Which of the Following Filariases are Transmitted by Insect Vectors

Question

Which of the following filariases are transmitted by insect vectors?
A) elephantiasis
B) river blindness
C) trichinosis
D) elephantiasis and river blindness

Accepted Answer

Both elephantiasis and river blindness are transmitted by insect vectors. Elephantiasis is transmitted by mosquitoes while river blindness is transmitted by blackflies. Trichinosis, however, is not transmitted by insect vectors but by consuming undercooked pork or wild game infected with the larval stage of the parasite.
