Health officials in the Ottawa Valley remain vigilant over the risks of West Nile virus.
A recent notice from the Renfrew County and District Health Unit continues to alert residents after the virus was detected in mosquitos collected in Arnprior and Deep River over the course of the summer.
West Nile virus is spread to humans by the bite of infected mosquitoes.
Most infected people will not show symptoms. However, one in five may show symptoms such as fever, headache, body aches, skin rash, and vomiting.
Approximately 1 in 150 people may develop severe illnesses affecting the central nervous system, including encephalitis or meningitis, with symptoms including stiff neck, confusion, tremors, numbness, and sudden sensitivity to light.
Older adults and those with weakened immune systems are at higher risk of severe illness.
While the risk of infection is low, Dr. Jason Morgenstern, Medical Officer of Health for RCDHU, noted that the first discovery of the virus earlier this year is “an important reminder for everyone to prevent mosquito bites and reduce breeding sites.”
The RCDHU reminds the public to take precautions to avoid contracting West Nile:
- Wearing light-coloured, long-sleeved shirts, long pants, hats, and socks, especially between dusk and dawn when mosquitoes are most active.
- Applying Health Canada-approved insect repellent containing DEET or picaridin on exposed skin
- removing standing water around your home, cottage, and campsite to eliminate potential egg-laying sites for mosquitoes
- keeping brushes and shrubs clear of overgrowth and debris to remove resting spots for adult mosquitoes
- turning over compost piles on a regular basis
- Making homes and businesses “bug tight” by ensuring windows and door screens fit tightly.
More information on West Nile virus and tips on keeping your family safe can be found on the RCDHU website.
