Which of the following diseases is NOT transmitted by mosquitoes?

Influenza is correct as it is not transmitted by mosquitoes. Influenza is primarily spread through respiratory droplets that are expelled when an infected person coughs, sneezes, or talks. The virus can also survive on surfaces for a period of time and can be contracted by touching contaminated surfaces and then touching the face.

In contrast, Venezuelan equine encephalitis, malaria, and dengue are all diseases that are indeed transmitted by mosquitoes. Venezuelan equine encephalitis is caused by a virus that is transmitted through the bite of infected mosquitoes, primarily the Culex species. Malaria is caused by parasites of the Plasmodium genus, which are spread through the bites of infected Anopheles mosquitoes. Similarly, dengue fever is caused by the dengue virus, which is transmitted by Aedes mosquitoes, particularly Aedes aegypti. Understanding the modes of transmission for different diseases is crucial for implementing effective control and prevention strategies in mosquito control programs.
