OSWEGO COUNTY, N.Y. -- Another case of EEE has prompted Oswego County health officials to go ahead with aerial spraying.

Officials confirm that Eastern Equine Encephalitis showed up in a pool of mosquitoes collected last week in the Village of Central Square.

The Oswego County public health director issued a declaration of "imminent threat to public health" and ordered aerial spraying be conducted as soon as possible in the Big Bay and Toad Harbor Swamp areas.

EEE, which claimed the life of an Oswego County girl last summer, is much rarer and is more often fatal than West Nile. There have been five reported human cases of the virus in the last 40 years in New York State and all of them were fatal.
