Overview:
"Vector-borne disease" is the term commonly used to describe an illness caused by an infectious microbe that is transmitted by a blood-sucking arthropod from an infected vertebrate (e.g., bird, rodent, deer or human) to a susceptible person by a blood-sucking arthropod. There are more than 55 mosquito species native to Virginia. Mosquitoes can carry and spread diseases such as West Nile virus, eastern equine encephalitis, La Crosse encephalitis, and St. Louis encephalitis.
