An engaging Table Topic discussion on Equine Viral Arteritis (EVA) was held at the 2009 American Association of Equine Practitioners Convention in Las Vegas, Nev. Approximately 40 equine practitioners attended the discussion, which touched on some current topics regarding the management and control of EVA.

Topics covered in this session ranged from vaccination of the pregnant and post-partum mare to import and export regulations of virally infected semen and stallions.

A disparity is found between countries regarding stallions. A few countries do not distinguish between seropositive, non-infected stallions and seropositive, persistently infected stallions, while a majority of the countries do differentiate between the two situations. A similar discussion touched on state-specific requirements involving semen and/or stallions persistently infected with equine arteritis virus.

A major point raised in this session is the lack of uniformity of procedures and protocols between states within the USA for dealing with this disease, the shipment of semen, and the handling of persistently infected stallions
