“Mosquito activity varies from year to year. It is important to know not all mosquitoes carry West Nile virus and the risk to residents remains very low.”

The municipality said to clean up stagnant water such as bird baths, flower pots, pool covers and clogged eavesroughs, and to ensure window screens on your home are tight-fitting and in good repair.

Officials also said people should cover up when they are outside and use insect repellent that contains DEET or icaridin.

“Wear light-coloured protective clothing, including pants and long-sleeved shirts,” a news release read.

According to the York Region website, those who get West Nile could experience flu-like symptoms including fever, muscle weakness, a stiff neck, confusion, severe headache and sudden sensitivity to light. Anyone who experiences these symptoms should seek medical attention.

“For a very rare few, the virus causes serious neurological illness including encephalitis (inflammation of the brain),” the website read. “About four out of five people who are infected with West Nile virus do not show any signs of illness.”
