How to prevent getting the West Nile virus

  • The most effective way to avoid getting the West Nile virus is to prevent mosquito bites, according to the CDC. Here are some tips from the CDC:
  • When heading outdoors – especially during peak hours from dusk to dawn -- use insect repellents with DEET, picaridin, IR3535 and some oil of lemon eucalyptus and para-menthane-diol. Use the repellent according to the product’s description.
  • Wear long sleeves, long pants and socks when outdoors. Mosquitos can bite through thin clothing, so beware.
  • Mosquito proof your home by installing or repairing window and door screens and by using air conditioning.
  • Empty standing water around your home. This includes removing standing water from places such as flowerpots, gutters, buckets, pool covers, pet water dishes and bird baths.
  • Report dead birds to local authorities as they may be a sign that the West Nile virus is circulating between birds and mosquitoes in the area.
