West Nile virus found in mosquitoes trapped in Mitchell, health unit says

Four out of five people infected with West Nile virus will not show any symptoms, but, in rare cases, severe illness including meningitis or encephalitis, or even death, can occur.

A Northwest Dallas resident is the first person to die from West Nile Virus in Dallas County in 2018, Dallas County Health and Human Services said Tuesday. In North America, that means that mosquito season - extending from the late spring through the fall - is West Nile season. A second round of larviciding will be starting shortly.

West Nile virus is a disease that is spread through the bite of an infected mosquito.

So for this year in Ontario, three probable or confirmed human cases of West Nile virus have been reported.

The mosquitos get the virus by feeding on infected birds. Symptoms, which include fever, nausea, headache and muscle aches, may last from a few days to a few weeks. People older than 50 are most at risk for WNV infection as are those with weakened immune systems.

Minimize time spent outdoors, especially at dawn and dusk when mosquitoes are most active.

Use insect repellent containing DEET when outside.

Wear clothing made of tightly woven fabric that covers the entire body.
