LANSING, Mich. (AP) – Officials say two additional cases of a virus that’s often fatal to horses have been discovered in Michigan.
The Michigan Department of Agriculture and Rural Development said Monday the animals infected with Eastern equine encephalitis were in Calhoun and Van Buren Counties.
Both had been euthanized before blood tests showed they tested positive for the virus, which is carried by mosquitoes.
Another case in Barry County was announced earlier this month.
State Veterinarian Dr. James Averill says horse owners should protect their animals from mosquito-borne illnesses with measures such as eliminating standing water and bringing horses indoors from early evening until after sunrise, the period when mosquitoes are most active. Horses also should be vaccinated.
Symptoms of eastern equine encephalitis include swelling of the brain, stumbling, depression and sometimes blindness.
