West Nile Virus Present in EOHU Area

The Eastern Ontario Health Unit (EOHU) is reminding the public that West Nile virus remains present in the area, as another pool of mosquitoes in the region has tested positive for the virus. The finding comes about one month after a first pool of mosquitoes in the area tested positive. So far this summer, there have been no confirmed human cases reported in the region.

“This finding shows that West Nile virus remains a concern in our area as long as mosquitoes are active, beyond September and well into the fall months,” says Dr. Paul Roumeliotis, Medical Officer of Health. “Residents should be aware and take the necessary precautions to protect themselves and their families.”

West Nile virus is spread to humans by the bite of an infected mosquito. For most people, the risk of illness from West Nile virus is low. However, it can cause serious illness in others. Mosquitoes can also carry other viruses that have the capacity to infect humans, such as Eastern Equine Encephalitis (EEE). The latter is rare but can cause serious complications in humans.

To protect yourself when outdoors, the EOHU recommends that you:

• Wear shoes, socks, long pants, and a long-sleeved shirt when outdoors for long periods or when mosquitoes are most active from dusk to dawn.
• Wear light-coloured clothing in tight-woven fabric.
• Use mesh bug jackets or hats.
• Consider the use of mosquito repellents used according to directions.
• Use mosquito netting or screened structures when sleeping outdoors.

To help control mosquito populations, you are encouraged to:

• Clean up and empty outdoor containers of stagnant water such as old tires, wheelbarrows, barrels, etc.
• Change water in bird baths at least once per week.
• Check swimming pools and make sure the pool’s pump is circulating.
• Turn over wading pools when not in use.
• Check and clear eaves troughs and drains to clear obstructions.
• Make sure drainage ditches are clear.
• Check flat roofs frequently for standing water.
• Carry out regular yard and lawn maintenance: collect or mulch any leaves or lawn cuttings, etc., that can serve as a food source for mosquito larvae.
• Turn over compost frequently and fill in low depression areas in lawns.
• Trim dense shrubbery where mosquitoes like to rest.
