Haldimand-Norfolk Health Unit reports positive West Nile virus mosquito pool in Haldimand 

The Haldimand-Norfolk Health Unit (HNHU) is reporting that one pool of mosquitoes collected from Caledonia on July 25, as part of the HNHU’s West Nile virus surveillance program, has tested positive for West Nile virus.

West Nile virus is transmitted to people through the bite of an infected mosquito, which can transmit the virus after feeding on the blood of infected birds.

Residents should take the following precautions to help protect themselves and their families from West Nile virus:

  • Use insect repellent when outdoors. Choose an insect repellent that contains DEET or other approved ingredients and always read and follow the directions on the label.
  • Minimize your time outdoors at dawn and dusk when mosquitoes are most active.
  • Cover Up. Wear light-coloured clothing, a long-sleeved shirt, long pants, and a hat to go outside when mosquitoes are most active.
  • Remove all standing water around your property to reduce mosquito breeding sites. Examples of standing water include flowerpots, wading pools, old tires, etc. Change water in birdbaths and pet bowls regularly.

While many people infected with the virus have no symptoms, some may have flu-like symptoms, such as fever, headache, body aches and fatigue. In rare cases, the virus can cause severe illness, resulting in hospitalization and even death. Symptoms usually develop between two and 15 days after being bitten by an infected mosquito.

The chances of getting West Nile virus from an infected mosquito are low. While anyone can become infected with West Nile virus, the risk of severe illness increases with age.
