Many serious equine diseases are preventable through vaccination and good biosecurity. Understanding the major categories of disease helps owners prioritize the right protective measures.
Viral Diseases
Equine influenza, rhinopneumonitis (EHV), West Nile virus, and Eastern/Western encephalitis are among the most significant viral threats, most of which are covered by core or risk-based vaccines. See our Horse Vaccines guide for details.
Bacterial Diseases
Strangles, tetanus, and Potomac horse fever are among the more common bacterial illnesses, ranging from highly contagious respiratory infections to environmental exposures tied to specific regions.
Strangles is one of the most contagious equine diseases and can spread through shared water troughs, tack, and even human clothing and hands.
Prevention
A solid vaccination schedule, quarantining new arrivals, and practicing good hygiene around shared equipment go a long way toward reducing disease risk at any barn.
