(KMOV) -- Mosquitoes in St. Clair County have tested positive for West Nile Virus.
The positive mosquito pool was collected in the Village of Shiloh on June 3rd. It is the first reported case of West Nile this season in St. Clair County.
The virus is transmitted to humans through the bite of mosquitoes that had been feeding on infected birds. The virus rarely affects humans, but the symptoms can begin up to 14 days after the initial bite. Overall, only two out of 10 people bitten by an infected mosquito will experience any illness.
The symptoms are mild and usually include a fever, headache and body aches. People over the age of 50 are most prone to feeling the symptoms.
The St. Clair County Health Department advices everyone to wear insect repellent while outside and clear any standing water away from your yard.
Last year there were 20 confirmed cases of West Nile Virus in Illinois, leading to one death.
