CHICAGO (CBS) — A man has died after contracting West Nile virus – in the first reported case and death in Illinois this year.
The Cook County Health Department said a suburban Cook County resident, over 70, fell ill with West Nile virus in early August and later died . West Nile was a contributing factor.
“The kids may be going back to school, but the mosquitoes are still out,” CCDPH chief operating officer Dr. LaMar Hasbrouck said in a press release. “West Nile virus is a risk until the first hard frost, so we still need to take precautions, especially at dawn and dusk when mosquitoes are most active.”
West Nile virus is caused by a mosquito bite. Common symptoms include fever, nausea, headache and muscle aches, the CCDPH noted. Four out of five infected people will be asymptomatic.
In rare cases, neuroinvasive diseases such as meningitis or encephalitis – and even death – can occur.
