Equine Infectious Respiratory Disease – Field Diagnostic Guidelines

Equine respiratory diseases, whether infectious or noninfectious, can significantly impact individual horse health and performance, and contagious respiratory disease may impact overall herd health. Equine respiratory disease etiologies range from viral and bacterial infections to environmental allergens or inflammatory factors. Diagnostic testing to determine the etiology of equine respiratory disease is strongly recommended in order to provide targeted treatment strategies, implement biosecurity protocols, and support overall herd health.
