The Peoria City/County Health Department reports its first human case of West Nile Virus this year. Health Department Administrator Greg Chance says people need to take precautions against mosquito bites until the first hard frost. Mosquitos can pick up West Nile Virus from infected birds.Symptoms include fever, nausea, muscle and headaches. But some people don’t get any symptoms and in rare cases a severe illness can result from West Nile Virus. The health department encourages people should exercise the four R’s: reduce exposure from mosquitoes from dusk to dawn, use repellent and protective clothing and report dead birds and standing water in ditches and roadways to municipal authorities.
