West Nile Virus

West Nile virus is a viral infection primarily transmitted through the bite of infected mosquitoes. While not all mosquitoes carry the virus, it is important to stay informed and take precautions during the peak mosquito season, typically from late spring to early fall. 

West Nile virus is a viral infection primarily transmitted to humans through the bite of infected mosquitoes, particularly the Culex species. While many people infected with West Nile virus may not show any symptoms, it can lead to severe complications, especially for older adults and individuals with weakened immune system. 


Reducing the risk of West Nile virus transmission starts with personal and community-based preventive measures. Here are some effective strategies you can adopt: 

  • Wear protective clothing: When spending time outdoors, especially during dawn and dusk when mosquitoes are most active, wear long-sleeved shirts, long pants, and socks to minimize exposed skin. 
  • Use insect repellent: Apply a Health Canada-approved mosquito repellent containing DEET or Picaridin to exposed skin and clothing. Remember to follow the instructions provided on the product label. 
  • Eliminate mosquito breeding sites: Remove standing water from your surroundings. Regularly empty and clean containers such as flowerpots, buckets, bird baths, and gutters to prevent mosquitoes from laying eggs. Keep grass and other vegetation short. 
  • Around the house: Install and maintain screens on doors and windows to keep mosquitoes outside while allowing fresh air to circulate. 

Stay Informed 

Community involvement plays a vital role in combatting West Nile Virus. Here’s how you can contribute: 

  • Stay Informed: Stay updated on West Nile virus activity in your area through local health authorities or official government websites. Be aware of any advisories or warnings and follow their guidelines. 
  • Share Knowledge: Help spread awareness about West Nile virus and preventive measures within your community. Encourage your friends, family, and neighbours to take necessary precautions. 

West Nile virus is a health concern during the warmer months, but by taking proactive steps, we can reduce the risk of infection. Protect yourself and your community by following the prevention strategies outlined above. Stay informed, stay vigilant, and together let’s combat West Nile virus.
