News Release: First Human Case of West Nile Virus Confirmed

For Immediate Release
Tuesday, September 20, 2022  | 4:00 p.m. | Windsor and Essex County

A Windsor-Essex County (WEC) resident has tested positive for West Nile virus (WNV). This marks the first clinically diagnosed and lab-confirmed human case for 2022 in our region. WNV is usually transmitted to humans through the bite of an infected mosquito that has fed on birds that carry the virus. Most people with WNV never develop symptoms and will not know that they have the virus. While WNV can infect people of all ages, people over the age of 50 and those with weakened immune systems are at higher risk for severe disease.

The mosquito species capable of spreading WNV have been identified throughout WEC through the health unit's surveillance program. This positive human case is a reminder for residents to continue to protect themselves from exposure while enjoying the outdoors. It is also important to remove any standing water around homes and businesses.

Here are some simple tips to help protect individuals from mosquito bites:

  • Remove all standing water on your property – call 311 or your local municipality to report standing water.
  • Use insect repellents that contain DEET, Icaridin or other approved ingredients on clothing as well as exposed skin. Read and follow the manufacturers' directions for safe use.
  • Wear long-sleeved shirts, pants, and a hat when outdoors. Light-coloured clothing is best as mosquitoes tend to be attracted to dark colours.
  • Limit the time you spend outdoors at dawn and dusk, when mosquitoes are most active.
  • Make sure that door and window screens fit securely and are free of holes.

The Windsor- Essex County Health Unit (WECHU) will continue to work closely with each municipality through the remainder of the season to monitor and control WNV in our community.
