A state epidemiologist says Louisiana is likely to have a below-average number of West Nile virus this year. But Julius Tonzel says people still need to keep up their guard against mosquitoes, which carry the virus. A case in New Orleans is among six around the state — and among five involving the brain or nervous system. That compares to one “neuroinvasive” case at roughly this time last year and six in 2019. There were 14 such cases in all of 2020, and 11 in 2019. The worst year was 2002, when there were 204. (AP Photo/Rick Bowmer)

West Nile Virus has been detected in mosquitoes in a number of areas around Louisville. Local media report no cases have yet been found in humans.

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.
