The most effective way to protect against West Nile Virus infection and all mosquito-borne diseases, is to prevent mosquito bites. Observe the “Five D’s of Prevention” during your outdoor activities:

  • Dusk/Dawn – Mosquitoes carrying WNV usually bite at dusk and dawn, so avoid or limit outdoor activity at these times.
  • Dress – Wear loose-fitting, long sleeved shirts and pants to reduce the amount of exposed skin.
  • DEET – Cover exposed skin with an insect repellent containing DEET, which is the most effective repellent against mosquito bites.
  • Drain – Empty any containers holding standing water because they are excellent breeding grounds for virus-carrying mosquitoes.
  • Doors – Make sure doors and windows are in good repair and fit tightly, and fix torn or damaged screens to keep mosquitoes out of the house.

Symptoms of WNV include headache, fever, neck discomfort, muscle and joint aches, swollen lymph nodes, and a rash – that usually develop three to 15 days after being bitten by an infected mosquito. The elderly, those with compromised immune systems, or those with other underlying medical conditions are at greater risk for complications from the disease.

Anyone with questions about West Nile Virus should speak to their healthcare provider or call their local county health department, environmental health office.
