How is EEE spread?
Mosquitoes spread the EEE virus. The virus is carried by birds that live in freshwater swamps and is generally found only in these birds and in mosquitoes that feed on birds but not people. In some years however, many birds get infected and other types of mosquitoes pick up the virus that also bite people and horses. The risk of getting EEE is highest from late July through September. The virus is spread by adult mosquitoes, which are killed by frost in the fall. The EEE virus is not spread by people and horses with the disease.
