West Nile virus found in Hamilton mosquitoes

The City of Hamilton has reported its first case of West Nile virus this summer.

A batch of mosquitoes trapped in the city this week tested positive.

Hamilton’s Medical Officer of Health has moved the virus risk level from low to moderate.

Last week, Niagara reported its first case of the virus in mosquitoes in St. Catharines.

Most people infected with West will have no symptoms.

About 20 per cent, including older adults or those with weakened immune systems, may experience West Nile fever.

Residents are being reminded to protect themselves against mosquito bites by:

• using bug spray containing DEET or Icaridin
• wearing light-coloured long sleeves and long pants when in mosquito areas, especially at dawn and dusk
• removing standing water from their property to prevent mosquito breeding
