West Nile Virus and Other Mosquito-Borne Illnesses
West Nile virus and other viral diseases carried by mosquitoes


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.

Mosquito Protection

  • Use a recommended mosquito repellent.
  • Cover arms and legs with long sleeves and long skirts or pants.
  • Avoid mosquito-prone areas in the mornings and evenings, when mosquitoes are most active.
  • Remove sources of standing water around your home where mosquitoes can breed, and make sure window screens are in good condition.
