The Iowa Health Department is reporting that it has confirmed five cases of West Nile virus in the state and is investigating several more cases.
The agency on Friday announced confirmed cases in Grundy, Linn, Lyon, Page and Plymouth counties. All those sickened by the virus have recovered.
In Nebraska, officials say 20 human cases have been confirmed, with no deaths reported.
The cases in Iowa and Nebraska come amid one of the largest national outbreaks of West Nile. More than 1,100 illnesses have been reported across the country.
Iowa health officials say state figures are typical for this time of year, but they urge people to use mosquito repellent when they are outdoors to protect against the virus.
