Mosquitoes usually are considered a nuisance pest, but occasionally they can transmit viruses to people and some animals. (ny.gov)
The mosquito Culiseta melanura is the primary vector (although other species of mosquito can also transmit the virus). (horsejournals.com)
In addition to mosquitoes, ticks and other bloodsucking insects can also transmit the virus after feeding on an infected bird. (horsejournals.com)
Mosquitoes are one of the main animal agents of human infectious disease, and the pathogens they transmit have likely been a selective force for human evolution (e.g., sickle cell disease [ 1 ]) and have also had profound political and historical effects [ 2 ]. (biomedcentral.com)
