Mosquito Borne Viruses

The most common mosquito-borne diseases found in eastern Virginia include West Nile Virus (WNV), St. Louis Encephalitis (SLE), Eastern Equine encephalitis (EEE), and Dog Heartworm (Dirofilaria immitis).

It is also not uncommon for Virginia to report a few imported cases of a mosquito-borne disease each year. Diseases may include malaria, dengue, or chikungunya, or Zika. These cases usually occur in people who have traveled to tropical or sub-tropical areas of the world.
