Manitoba Identifies First Mosquitoes Carrying West Nile Virus

The first batch of Culex tarsalis mosquito samples infected with West Nile virus have been identified in Manitoba.

The province says the infected mosquitoes were collected during the week of July 20 from adult mosquito traps in Altona, West St. Paul and Winkler.

No humans have been infected, but officials say the potential for exposure to infected Culex tarsalis mosquitoes is present throughout southern Manitoba.

“The risk of exposure to WNV is expected to continue in the coming weeks, particularly if warm and dry conditions persist, as these are ideal for Culex tarsalis development and activity,” the province said in a release.

There are no plans for adult mosquito control in Altona, West St. Paul, Winkler or elsewhere in the province.

You can reduce your risk of mosquito bites and exposure to West Nile virus by:

• reducing the amount of time spent outdoors during peak mosquito hours between dusk and dawn;
• using appropriate mosquito repellent;
• wearing light-coloured, loose-fitting clothing; and
• maintaining door and window screens so they fit tightly and are free of holes.
