Health officials warn West Nile will be back this year

Posted: Updated:

YAKIMA, Wash.-- Warmer temperatures bring more people outside, but it also means the return of mosquito season, and the danger of West Nile Virus.

The state Department of Health has started up its dead bird reporting system to monitor where West Nile develops.

Last year, there were only five confirmed cases in the state, including one in Yakima County and one in Franklin County, but none of those involved humans or birds. 

That's way down from previous years.

"Somebody whose been exposed to West Nile Virus won't even know it but they will build up an immunity. The population gets less susceptible," said Gordon Kelly with the Yakima Health District.

Health officials say they know the virus will hit every year, so now it's about informing people and making sure folks take preventative measures like using insect repellant.
