West Nile Virus Detected in Mosquitoes Near Picton

Date: August 24, 2023

Hastings Prince Edward Public Health (HPEPH) has confirmed that mosquitoes carrying West Nile virus (WNV) have been identified in the Picton area as part of routine mosquito surveillance.

This marks the second confirmed detection of the virus in the region this season. Earlier in the month, WNV-positive mosquitoes were also found in Quinte West.

West Nile virus primarily circulates among birds and is transmitted by mosquitoes that feed on infected birds. The virus can then spread to humans and animals through the bite of an infected mosquito.

Early signs of infection may include fever, muscle weakness, stiff neck, confusion, severe headache, light sensitivity, tremors, numbness, or vision problems.

Public health officials note that most people experience mild symptoms or none at all. However, in rare and serious cases, the virus can lead to encephalitis, an inflammation of the brain. Anyone who believes they may be experiencing symptoms of West Nile virus is advised to contact a primary care provider.

Mosquitoes are most active during dawn and dusk, and residents are encouraged to take precautions if outdoors at these times. Recommended measures include:

• Wearing light-coloured, long-sleeved clothing, long pants, socks, and hats

• Applying insect repellent containing DEET or Icaridin

• Eliminating standing water around homes, such as birdbaths or small pools

• Ensuring windows and doors are properly screened

HPEPH continues to monitor mosquito populations and reminds residents that prevention remains the most effective way to reduce the risk of infection.
