Abstract
EVA is an infectious disease of equids that occurs in many parts of the world and is caused by EAV (Timoney and McCollum, 1993; Glaser et al., 1997). Most EAV infections are subclinical but occasional outbreaks of disease occur that are characterised by any combination of influenza-like illness in adult horses, abortion in pregnant mares, and interstitial pneumonia in very young foals. Up to 60% of stallions infected with EAV become persistently infected carriers and shed virus continuously in semen. Persistence of EAV in the male reproductive tract is testosterone-dependent, and persistently infected stallions function as a natural reservoir that can disseminate virus to susceptible mares at breeding (Timoney and McCollum, 1993).
