Washoe County has it's first West Nile Virus case acquired locally this year.

"People may feel, with the end of summer approaching, that the risk of being bitten by mosquitoes is reduced", said Dr. Charles Gardner, Medical Officer of Health for the Simcoe Muskoka District Health Unit. The latest report shows 79 human West Nile Virus cases in Nebraska with 42 being severe and four deaths, which is the highest death rate in the nation.

Most WNV human cases in Wisconsin occur during the months of August and September. "Even though we monitor mosquito activity, conduct larvicide treatments, and fog areas of known activity, this is a reminder that people must be vigilant and take personal measures to keep from being bitten by mosquitoes", said Dick. Symptoms of WNV include: fever, rash, headache and joint pain. Symptoms of the more serious West Nile encephalitis include inflammation of the brain, disorientation, convulsions and paralysis. Older adults and people with compromised immune systems are at an increased risk of severe disease from the virus. Key prevention tips include using insect repellent and wearing long-sleeved shirts and long trousers. The health unit encourages the public to seek medical attention if they are experiencing any symptoms related to West Nile virus.

Applying an insect repellant with DEET, IR 3535, picaridin, or oil of lemon eucalyptus to clothing as well as exposed skin. Mosquitoes are also most active around dusk and dawn.

Make sure that your doors and windows have tight-fitting screens to keep mosquitoes out.
