Mosquito-borne illnesses in Mississippi include West Nile virus, St. Louis encephalitis, Chikungunya virus, and Eastern Equine encephalitis. These illnesses affect birds, animals and humans, causing flu-like symptoms in people who are bitten by infected mosquitoes. Occasionally, illness can be severe, leading to meningitis or encephalitis.
