ABSTRACT: The prevalence of antibodies against equine viral arteritis virus (EVAV) in healthy horses raised in Northwest, Western Central and North Central regions of the State of Paraná, Brazil was investigated. According to calculated sample size, serum samples of 653 horses were analyzed through standard virus neutralization test. No horse had antibodies to EVAV in Northwest (0/236) and in Western Central (0/99) regions. In North Central region frequency was 0.62% (2/318), with an overall prevalence of 0.30%. It can be concluded that EVA does not represent a problem of epidemiological importance in the studied regions of Paraná.
