Which virus is NOT known to be transmitted by mosquitoes?

Explanation:
Mosquito transmission applies to viruses that rely on mosquitoes as vectors to move between people. West Nile virus, Dengue, and Zika all spread through bites from infected mosquitoes, with specific mosquito species (like Culex for West Nile and Aedes for Dengue and Zika) playing a key role in their transmission cycles. Smallpox, on the other hand, does not use mosquitoes at all. It spreads mainly through respiratory droplets during close person-to-person contact and through direct contact with infected lesions or contaminated objects. There is no mosquito vector involved in the transmission of smallpox. So the virus not known to be transmitted by mosquitoes is the one that spreads by direct contact and droplets rather than via a mosquito bite.
