Epizootics in horses have continued to occur regularly in the United States. People become infected with this virus by other mosquito species that create a bridge between infected birds and mammals.
The blacktailed mosquitos favored habitats are freshwater hardwood swamp-like environments located in areas from the Great Lakes and Maine southward to southern Florida. Mosquitoes are carriers vectors for many diseases including West Nile Virus WNV Eastern Equine Encephalitis EEE and Zika Virus. Eastern Equine Encephalitis EEE is spread to horses and humans by infected mosquitoes.
Eastern Equine Encephalitis is transmitted by mosquitoes of the Aedes Coquillettidia and Culex species. Aedes Albopictus also is a capable vector of Dengue Fever Yellow Fever and Dog Heart Worm. Mammals become infected by mosquito species mainly from the Aedes group and the Coquillettidia group that feed on both birds and mammals.

Eastern equine encephalitis involves transmission of the disease-causing virus from EEE-virus infected Culiseta melanura mosquitoes commonly called the blacktailed mosquito. Although it is extremely rare EEE can have very serious symptoms.
Eastern equine encephalitis virus EEEV is maintained in an enzootic cycle involving Culiseta melanura mosquitoes and avian hosts. The virus was found in Culiseta melanura species mosquitoes which is a species that primarily bites birds. Other mosquito species that feed opportunistically on mammals have been incriminated as bridge vectors to humans and horses.
Eastern equine encephalitis virus EEEV is maintained in an enzootic cycle involving Culiseta melanura mosquitoes and avian hosts. In Connecticut the virus has been found in trapped mosquitoes in most years. Eastern Equine Encephalitis is a rare but serious disease caused by a virus that is transmitted by mosquitoes.
