This year’s unusually wet spring and summer has contributed to a much higher than normal number of mosquitoes testing positive for West Nile virus in Peel.

To date, there have been no human cases of the illness confirmed in the region, according to Peel Public Health.

While West Nile typically is a mild disease in humans, rare complications can occur.

About one in five people infected will develop a fever with other symptoms. Less than one per cent of infected people develop a serious, sometimes fatal, neurological illness.
