Porcine parvovirus (PPV) is a member of the Parvoviridae family. Swine infected with the virus can experience reproductive problems, including abortion, small litters, still births, neonatal deaths and weak piglets. There is no clinically apparent disease in non-pregnant pigs. PPV is endemic in most countries with large pig populations. The virus can be transmitted via oronasal, transplacental and venereal routes, but oronasal is the most important route of infection.
