West Nile virus cases in Louisiana are way down from a year ago but the state epidemiologist says people statewide still need to protect themselves against mosquitoes.
Knowing where people have become ill or where the virus has been found in mosquito pools can give people a false sense of security because West Nile is statewide, Dr. Raoult Ratard said Thursday.
"People are insisting, 'It's not in my parish, it's next door.' But that means nothing," Ratard said. "Next week it may be in your parish. The risk is there."
