Mosquitoes in Whitby Test Positive for West Nile Virus
Alert residents! The Durham Region Health Department has confirmed that mosquitoes collected in Whitby have tested positive for the West Nile virus (WNv). This is a concerning trend, as it marks the 19th batch this season across the region.
Where Are the Cases?
In addition to Whitby, the virus has been detected in several other municipalities: four batches in Clarington, seven in Oshawa, three in Ajax, and four in Pickering. The latest samples were collected from a designated mosquito trap site in Whitby.
Understanding West Nile Virus
West Nile virus is transmitted to humans through the bite of an infected mosquito that has fed on an infected bird. Fortunately, this virus cannot be spread from person to person or from birds directly to humans.
Symptoms to Watch For
While many who contract WNv may only experience mild symptoms such as fever, body aches, and mild nausea, others could face more severe illnesses. Severe symptoms can include muscle weakness, confusion, and sensitivity to light, typically appearing 2 to 15 days after exposure.
Precautionary Measures You Should Take
Though the overall risk remains low, it’s crucial to stay vigilant. The Durham Region Health Department recommends that residents:
- Wear long sleeves, pants, and socks—preferably in light colors—during dusk and dawn.
- Apply insect repellent containing DEET or Picaridin, following Health Canada guidelines.
- Eliminate standing water around your property to prevent mosquito breeding.
- Ensure that window and door screens are in good condition to keep mosquitoes out.
Community Efforts to Combat Mosquitoes
The Durham Region is actively treating catch basins and stagnant water areas with larvicide to help manage mosquito populations. This community effort is essential for reducing the risk of mosquito-borne illnesses.
