He says while they still have another five to six weeks of trapping to go, the numbers are normal for this time of year. "So we suspected Meningitis, but not West Nile virus".
DHS says most human cases happen during August and September.
The McHenry County Department of Health confirmed its first case of West Nile Virus in a human in 2017 on Wednesday.
The virus is carried by mosquitoes, which means residents should eliminate breeding areas such as tires, gutters, catch basins and containers that can collect water. The department does surveillance of mosquito populations with traps strategically located throughout the community, and tests mosquitos for such diseases as Zika and West Nile virus. "The more time someone is outdoors, the more time the person is at risk of being bitten by an infected mosquito; that is why we encourage everyone to take all precautions against mosquito bites".
While it's too early to predict when exactly Ontario will see a peak this summer, Giordano said the number of positive mosquito traps are rising every week.
The media release says the health department applied a larvicide created to prevent mosquitoes from hatching in the infected areas. Infected mosquitoes can then spread the virus to humans and other animals when they bite.
If you go outdoors, you can put on insect repellent containing DEET, picaridin, Oil of Lemon Eucalyptus or IR3535 to help keep the mosquitoes away. Those who do can show symptoms such as fever, headache, body ache, fatigue, nausea or rash.
When weather permits, wear long sleeves, long trousers and socks when outdoors.
Make sure window and door screens are in good fix to prevent mosquito entry.
