OGLE COUNTY (WREX) — The Ogle County Health Department confirms the first positive pool for West Nile Virus reported in Ogle County for 2019.
The pool of mosquitoes found near Polo tested positive.
“With this being the first positive sample, maintaining vigilance to prevent exposure is extremely important,” the health department said in a news release.
Monitoring for West Nile virus in Illinois includes laboratory tests for mosquito batches, dead crows, blue jays, robins and other perching birds, as well as testing humans with West Nile virus-like symptoms.
People who observe a sick or dying crow, blue jay, robin or other perching bird should contact their local health department, which will determine if the bird will be picked up for testing.
Common symptoms in humans include fever, nausea, headache and muscle aches. Symptoms may last from a few days to a few weeks. However, four out of five people infected with West Nile virus will not show any symptoms. In rare cases, severe illness including meningitis or encephalitis, or even death, can occur. People older than 50 and individuals with weakened immune systems are at higher risk for severe illness from West Nile virus.
Precautions include practicing the three “R’s” — reduce, repel and report.
