IDPH confirms first human West Nile Virus case in state this year

Posted: Updated:

SPRINGFIELD - Illinois Department of Public Health officials have confirmed the first human West Nile Virus case reported in the state this year.

IDPH officials say the St. Clair County Health Department reported that a girl became ill with the virus in August.  Officials also say West Nile Virus was identified in St. Clair County in a mosquito batch in May 2015.  Last year, 44 people in Illinois became ill due to West Nile Virus, resulting in four deaths.

The state Public Health Department is reminding the public that West Nile Virus is transmitted through mosquito bites, and that common symptoms include fever, nausea, headache, and muscle aches.  Rare side effects, such as severe illness and even death, can occasionally occur.  Four out of five people infected with West Nile Virus will not show any symptoms or become ill, and individuals over the age of 50 and those with compromised immune systems are more likely to become ill.
