Positive West Nile Virus Case Confirmed in Brighton Mosquito Traps
The Haliburton, Kawartha, Pine Ridge District Health Unit (HKPR District Health Unit) is advising the public that a mosquito pool tested positive for West Nile Virus (WNV) in the Brighton area. This marks the first positive case in the region for the season. The mosquito was collected from one of the traps set by health officials on August 1st, 2024.
HKPR District Health Unit conducts weekly mosquito trapping and testing throughout the HKPR district area during the summer and early fall months to monitor for WNV activity. While no mosquitos tested positive for WNV in the district area last year, there were confirmed human cases in Ontario.
"As we enter the peak season for West Nile Virus, it's crucial for everyone to take preventive measures seriously," said Anne Marie Holt, Director of Health Protection with the HKPR District Health Unit. "Protecting yourself from mosquito bites and eliminating standing water around your home are simple yet effective ways to reduce the risk of infection. Negative mosquito pools don’t guarantee that WNV is not present in the community; it only means we didn't catch a positive mosquito pool. Therefore, it is important for the community to stay vigilant."
WNV is primarily transmitted through mosquito bites. Although the majority of WNV cases do not show symptoms, some infected individuals may experience mild flu-like symptoms, including fever, headache, and body aches. While others may develop severe neuro-invasive disease, which disproportionately affects older adults.
To prevent WNV, the public is advised to cover up and clean up:
Prevent mosquito bites: Cover up when outdoors between dusk and dawn, use insect repellent containing DEET or icaridin.
Clean up: Clean up around your property by removing thick brush, cutting down high vegetation, removing sources of standing water from your property i.e. old tires, wheelbarrows and clean eaves troughs to reduce mosquito habitats. Also, prevent mosquitoes from entering your home by ensuring your window screens are tight fitting and in good repair.
