Manitoba has its first human case of West Nile virus this year.

A Winnipeg woman in her 40s is believed to have contracted it in the city earlier in the summer. She has mild symptoms, according to provincial health officials.

Provincial officials said the risk for more human cases of the virus is low, but the warm temperatures have increased the numbers of mosquitoes that carry the virus.

People should be cautious about spending time outdoors in the evening when more Culex tarsalis mosquitoes, the type that carry West Nile virus, are out.

Officials also recommend wearing repellent, light coloured clothing and keeping door and window screens tightly fit.

Manitobans are also asked to help reduce the spread of the mosquitoes by eliminating any standing water.

More information on the virus and how to protect yourself can be found on the Manitoba Health website.
