Mosquitoes in Ottawa have been found to carry the West Nile virus

As the summer months approach, it's important for residents of Ottawa to be aware of the precautions they can take to protect themselves against West Nile virus. This virus, transmitted through the bite of an infected mosquito, can pose a risk until the first hard frosts of the fall.

Precautions and Protection Measures

To minimize the risk of West Nile virus infection, follow these simple guidelines:

  1. Remove Standing Water: Eliminate any unnecessary standing water around your home, including from birdbaths, ornamental pools, and clogged drains. Even small amounts of water can serve as a breeding habitat for mosquitoes.
  2. Use Insect Repellents: Apply insect repellents containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin and clothing when outdoors.
  3. Wear Protective Clothing: Wear long-sleeved shirts, long pants, and socks when outdoors, especially during peak mosquito hours (dawn and dusk).
  4. Install or Repair Screens: Ensure that windows and doors have screens to prevent mosquitoes from entering your home.
  5. Avoid Peak Mosquito Hours: Limit outdoor activities during the early morning and evening when mosquitoes are most active.

Additional Information

  • Risk Period: The risk of West Nile virus infection is highest from August to early September, but it can persist until the first hard frosts of the fall.
  • Symptoms: Most people infected with West Nile virus do not develop symptoms, but about 20% may experience flu-like symptoms such as fever, headache, and muscle aches. Less than 1% of infections result in serious illnesses that can invade the central nervous system.

By following these guidelines, residents can reduce their exposure to mosquitoes and minimize their risk of contracting West Nile virus. It's also important to remember that the risk is higher for individuals with weakened immune systems, such as seniors.

As of now, only one human case of West Nile has been reported province-wide as of Aug. 3. However, public health advises residents to remain vigilant and take the necessary precautions to protect themselves.

In addition, residents are asked to regularly treat or replace water in use, like ornamental pools or bird baths, to prevent mosquito breeding. Public health also recommends wearing light-coloured, tightly woven, loose-fitting clothing to protect exposed skin.

Stay safe and enjoy the summer months in Ottawa by taking these simple steps to protect yourself against West Nile virus.
