Equine influenza virus (EIV) is a highly contagious respiratory disease that is endemic to horses in the US and around the world providing economic morbidity in countries with substantial breeding and racing efforts.1 Significant factors influencing susceptibility are age, common effecting horses 1-5 years of age, and exposure with higher incidence seen in horses living in high density populations.1,2 The virus spreads rapidly in aerosolized droplets dispersed by coughing from infected horses during the 1-3 day incubation period. Although horses can be vaccinated, antigenic drift is an issue as immunity and protection may only last for a few years.3 Symptoms include fever, cough, nasal discharge, and secondary bacterial complications.1,2 H3N8 is the Influenza Type A strain associated with current cases of EIV.1,2,3 The Fluxergy EIV Assay specifically detects the H3N8 strain via PCR of deep nasopharyngeal swab providing immediate turnaround times and accuracy in virus identification.
