West Nile virus

Mosquitos which tested positive for West Nile Virus were found recently near the Whiteside County Fairgrounds in Morrison.

The virus was first detected in the county in July, and it’s also been found in Carroll and Ogle Counties.  Whiteside County Health Department Public Health Administrator Beth Fiorini said the last cases usually show up in late August, making this a highly unusual case.

“It’s been a really, really dry season," she said. "I don’t know if that’s why. We haven’t had rain in Whiteside County for weeks.”

Early Finding For West Nile Virus In Sterling

A batch of mosquitoes recently tested positive for West Nile Virus in Whiteside County. Health officials say it’s an early result in the testing season.

Health officials have been testing for West Nile Virus since 2002.

Gene Johnston, Director of Environmental Health at the Whiteside County Health Department, says it’s common to get positive results -- but usually in August or September.

A batch of mosquitoes collected near Genoa has tested positive for West Nile Virus.

 

This is the first time this year a DeKalb County Health Department mosquito trap has yielded a positive test for West Nile.  

 

West Nile virus transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. 

 

Health officials say that mosquitoes which carry West Nile virus breed in stagnant water, like street catch basins and ditches, and multiply rapidly.

Illinois’ Department of Public Health announced its first positive test of a bird for West Nile virus in the state this year.

    

The Blue Jay was collected south of Champaign in Arcola Township last May.

Zika virus and West Nile are both transmitted by mosquitoes.

Common symptoms of West Nile virus include fever, nausea, headache and muscle aches. Symptoms can last from a few days to a few weeks.

However, four out of five people infected with the virus will not show any symptoms.

West Nile Virus Detected In DeKalb County

Health officials in DeKalb County detected the first mosquitoes with West Nile Virus this summer.

Municipalities say they monitor catch basins that help eliminate mosquitoes, but recent heavy rains may have flushed out mosquito larvae.

Several other counties in the state already reported cases of West Nile Virus in mosquitoes this year. But there has yet to be a human case so far.

The mosquitoes get the virus from feeding on dead birds. The Health Department is collecting dead birds to be sent to the state lab for testing.
