West Nile Virus

Mosquitoes that have fed on the blood of infected birds spread the West Nile Virus (WNV). In the summer of 2002, four birds in Nova Scotia tested positive for WNV.

The chance of being bitten by an infected mosquito is low as not all mosquitoes carry or pass on the virus. The risk of getting sick from the virus is even lower as four out of five people infected with the virus will never get sick and others will only develop mild symptoms. However, in some cases the virus can cause serious health problems.

Protection from mosquito bites

  • Use insect repellants that contain DEET,
  • Limit time outdoors at dusk and dawn when mosquitoes are most active.
  • Wear long-sleeve shirts, pants, socks, a hat and light coloured clothing as mosquitoes are less attracted to light colours.
