Mosquitoes can be a major annoyance during warmer months in Vermont and can occasionally transmit serious diseases. West Nile Virus (WNV) has been detected in every county of Vermont and typically infects three or fewer Vermonters each year. Eastern Equine Encephalitis (EEE) has also been detected in Vermont and caused two deaths in Rutland County in 2011.
Climate change is expected to affect mosquito-borne diseases in two ways:
Increase the risk for people to get diseases that are already here.
Bring in mosquito species that did not previously exist here, increasing the possibility for other mosquito-borne diseases to spread in Vermont.
