EQUINE VIRAL ARTERITIS IN CROATIA: EXPERIENCES AND GUIDELINES

Equine viral arteritis (EVA) is a contagious viral disease caused by a member of Arteriviridae family, genus Alphaarterivirus. Infected ungulates can develop a respiratory illness or abort. Respiratory infections are often subclinical or mild but it can lead to interstitial pneumonia and death. Abortions can come without any other clinical symptoms in any phase of the gestation. EVA is an important disease in the horse industry due to economic losses, especially in breeding. Studs have a central role in epizootiology of EVA. In general, horses achieve sterile immunity in a period up to 28 days after the infection. On the other hand, studs can stay carriers and excrete virus in semen for the rest of their life. Not every ejaculate contains pathogen so multiple molecular tests and virus isolation attempts must be undertaken. Croatia has introduced EVA surveillance and eradication program in 2009. First, vaccination was banned since surveillance was focused on serological testing of the studs and mares in case of abortion. Studs with positive virus-neutralization test had semen tested to rule out carrier state. Carrier studs were excluded from further breeding mainly by castration. In 2010, seroprevalence was 28.8% and it dropped to 4.4% and 6.8% in the last two years of the program implementation. These numbers are clear evidence of surveillance and control measures effectiveness. The main challenge was to keep the implementation of the programme on a satisfactory level in the whole country but finding and excluding carrier studs from breeding led to the eradication of the disease in horse farms where measures were fully in place. In summary, measures implemented in Croatia: ban of vaccination, serological testing, finding carrier studs and excluding them from future breeding will ensure control of EVA and can lead to eradication.
