Posted in: Pork Insight Articles by admin on June 5, 2017
SVA has been isolated from pigs since 1988 and was reported as picornavirus-like particle until 2002. Anti-SVA antibodies have been detected in cattle, mice and pigs as well as presenting non-pathogenicly in humans. In pigs SVA is believed to be the causative agent of idiopathic vesicular disease. In July 2015 Brazil reported a novel clinical disease syndrome associated with SVA, neonatal losses syndrome was reported affecting piglets 0-7 days of age. The fatality rate was higher (40-80%) in 0-3 day old piglets. Litters older than a week did not seem to be affected clinically. Once disease was established it had a relatively fast onset of a wasting syndrome progressing to mortality.
