About Equine Rhinitis Viruses

Equine rhinitis viruses A and B (ERAV and ERBV) cause respiratory disease in horses. Clinical signs of ERAV and ERBV mirror those of other respiratory pathogens such as equine influenza virus and equine herpesviruses. 

Equine rhinitis viruses appear to be transmitted through direct contact with infected horses; through aerosolized droplets when horses sneeze, cough, or snort; or through contaminated objects such as tack, grooming supplies, buckets, and water troughs.
