A recent report from the Wisconsin Department of Agriculture, Trade, and Consumer Protection has confirmed a case of equine herpesvirus in a horse in Green Lake County. The affected horse, a 13-year-old Mustang gelding, developed a fever and tested positive for EHV on Aug. 26. The horse is currently alive and under voluntary quarantine.
EDCC Health Watch, a marketing program by Equine Network, uses information from the Equine Disease Communication Center (EDCC) to provide verified equine disease reports. The EDCC is a nonprofit organization supported by industry donations to offer open access to infectious disease information.
EHV 101
Equine herpesvirus is highly contagious among horses and can lead to various illnesses, including respiratory issues, abortion in broodmares, and equine herpes myeloencephalopathy (EHM).
Symptoms of EHV-1 infection in horses may include fever, cough, decreased appetite, depression, nasal discharge, and in pregnant mares, abortion. Neurological signs associated with EHM can include ataxia, limb weakness or paralysis, urine retention, loss of tail tone, and recumbency.
The virus spreads through close contact with infected horses, contaminated equipment, or contact with individuals who have been in contact with infected horses. Regular biosecurity measures, such as hygiene practices and disinfection, are essential to prevent disease transmission.
While EHV-1 vaccines can reduce viral shedding, they do not provide protection against the neurological form of the disease. Emphasizing routine biosecurity protocols is crucial for controlling disease spread and prevention.
