West Nile virus found in Hamilton mosquitos, city says

Mosquitos in Hamilton have tested positive for the West Nile virus, says the city.

It's the first batch of mosquitos to be found carrying the virus this year, the city said in a news release Friday.

The city has increased the risk of West Nilefrom low to moderate.

"In the warmer months it is important to take precautions to avoid illnesses spread by insects," said Dr. Bart Harvey, an associate medical officer of health.

The city recommends using insect repellent containing DEET or lcaridin and wearing loose-fitting, light-coloured clothing in places where mosquitos often are, such as in wooded areas, golf courses and gardens, especially at dawn and dusk.

It also says to remove standing water from private property to avoid mosquitos breeding there.

About 80 per cent of people infected with West Nile have no symptoms, the city says. Adults who are older or with a weakened immune system may experience a fever, or develop more severe symptoms such as inflammation in the brain.

The city says itcontinues to assess the risk of West Nile and has completed two rounds of treatments on street catch basins and surface waters on public land.
