Porcine parvovirus (PPV) was transmitted by direct contact between experimentally infected and susceptible pigs at 1 and 2 weeks, but not at 4, 8, 16, or 25 weeks, after experimental infection. In contrast, PPV was found to remain infectious for at least 14 weeks in uncleaned rooms previously vacated by experimentally infected pigs. These findings suggest that facilities contaminated by secretions and excretions of infected pigs may provide the major means by which PPV survives between episodes of acute infection.
