West Nile Virus Detected in Greater Sudbury Crow

Public Health Urges Mosquito Bite Prevention Amidst Detection

Public Health Sudbury & Districts has confirmed a positive West Nile virus (WNV) case in an American Crow within the Greater Sudbury area. This finding serves as a crucial reminder that the virus, though posing a low overall risk, remains active in the region, necessitating ongoing vigilance.

Virus Activity and Human Risk

The detection follows a human case in 2023, with no reported human infections in 2024. However, **Jonathan Groulx**, a manager with Public Health Sudbury & Districts, emphasized the continued presence of WNV. He stated, “the last person confirmed to have been infected with West Nile virus infection in our area was in 2023. However, this infected bird reminds us that although the overall risk of a person becoming sick with West Nile virus is low, the virus is still present.”

WNV is transmitted through mosquito bites. While most infected individuals exhibit no symptoms, some may develop mild, flu-like illness. In rare instances, severe neurological complications can arise.

Peak Risk Season Approaches

Late summer traditionally represents the period of highest risk for WNV transmission. Mosquito populations may carry elevated viral loads, and public awareness regarding protective measures can sometimes wane. Proactive steps are vital for safeguarding against infection.

Preventing Mosquito Bites

Home-Based Precautions

• Ensure window and door screens are intact to prevent mosquitoes from entering dwellings.
• Eliminate potential breeding sites by removing any standing water around your property.

Personal Protection Strategies

• When outdoors, particularly during dawn and dusk when mosquitoes are most active, wear light-colored clothing that covers arms and legs.
• Apply an approved insect repellent, adhering strictly to the manufacturer’s usage guidelines.

Reporting Dead Birds

Individuals concerned about potentially infected dead birds can report their findings to the Canadian Wildlife Health Cooperative by calling 1.866.673.4781 or submitting a report online via their dedicated tool.

According to the Centers for Disease Control and Prevention (CDC), mosquito season can extend into the fall, with the potential for WNV transmission continuing as long as temperatures remain above freezing and mosquitoes are active (CDC).
