The Louisville Metro Department of Public Health and Wellness has reported West Nile in at least seven zip codes around the city. But health officials say the threat to humans in very low.
Not only have no cases been detected in humans, most who do get infected either show no symptoms or relatively mild symptoms. Fewer than 1% develop serious illness from the virus.
WAVE3 reports there were just three known cases of West Nile in Louisville residents in 2021, but no deaths.
Only a handful of suspected cases have been reported in Lexington in recent years, with a bird testing positive last year.
