Two horses have died in Polk County’s Green Swamp area from Eastern equine encephalitis, a mosquito-transmitted illness. The horses reportedly did not have EEE vaccinations. At this time, there have been no reported or confirmed mosquito-borne diseases in humans in Polk County.
Eastern equine encephalitis is a virus disease transmitted to horses and humans by mosquitoes. Polk County will be responding today with aerial application of adulticide and larvicide to reduce the populations of mosquitoes in the affected area.
“We’ve only seen this in the Green Swamp area right now,” said Dr. Jackson Mosley, interim manager of Polk County’s Mosquito Control Program. “We have not seen it in the Southern portion of the county yet, but people throughout the county should take precautions. Eastern equine encephalitis transmission cycle involves wild birds and specific mosquitoes. Humans and horses are not part of the transmission cycle. However, if infected, they can become seriously ill.”
To avoid being bitten by mosquitoes and to limit exposure, residents and visitors are reminded to “Drain and Cover”:
