DENVER (AP) — The Colorado Department of Agriculture says two cases of West Nile virus have been diagnosed in horses in Fremont and Weld counties, representing the first cases of the disease reported in horses in the state this year.
Agriculture officials said Thursday the horses are being treated.
Humans and animals can be infected with the disease from mosquitoes. Symptoms in infected horses include a head tilt, muscle tremors, stumbling, lack of coordination, weakness of the limbs, or partial paralysis.
State officials say vaccines can help protect horses from infection, but owners also should remove stagnant water sources, keep animals inside during the early morning and evening hours when mosquitos feed, and use mosquito repellents.
