Equid alphaherpesvirus 1, commonly known as Equine herpesvirus 1 (EHV-1), is a contagious virus affecting horses that can cause respiratory illness, neurological disease, and abortion in pregnant mares. The virus is notable for its ability to spread rapidly through direct contact or contaminated environments, and it can lead to severe outcomes such as encephalitis, resulting in ataxia, paralysis, and death in affected animals. Many horses carry the virus latently without showing symptoms, but stress or other factors can trigger outbreaks with significant impacts on equine health and the horse industry.
The EHV-1 outbreak in 2025 has drawn attention due to its connection to recent equestrian events, as highlighted in news reports linking cases to gatherings in Texas during November. This has raised concerns among horse owners and veterinarians about the potential for widespread transmission, given the virus's history of causing quarantines and economic losses in past incidents, such as a 2006 outbreak in Florida. The situation underscores the ongoing challenge of managing infectious diseases in mobile horse populations.
Authorities and industry groups are emphasizing biosecurity measures, including isolation of new or exposed horses and disinfection protocols, to curb the spread. The outbreak serves as a reminder of the virus's persistent threat, urging heightened vigilance to protect equine welfare and prevent further disruptions to competitions and breeding operations.
