Which of the following transmits ‘Yellow fever’ and ‘West Nile fever’ ?

  • A.Ticks
  • B.Kissing bugs
  • C.Deer flies
  • D.Mosquitoes

Answer: D

Both are transmitted by Mosquitoes.

Yellow fever virus is spread mainly by Aedes mosquitoes, especially Aedes aegypti, and West Nile virus mainly by Culex mosquitoes, with birds as its main reservoir.

Ticks transmit diseases such as Lyme disease and Kyasanur Forest disease, kissing bugs (triatomines) transmit Chagas disease, and deer flies transmit tularaemia and loiasis. None of them is the vector of these two fevers.
