Spillover of Canine Parvovirus Type 2 to Pigs, South Dakota, USA, 2020

Abstract

In 1978, canine parvovirus type 2 originated from spillover of a feline panleukopenia–like virus, causing a worldwide pandemic of enteritis and myocarditis among canids. In 2020, the virus was identified in pigs in South Dakota, USA, by PCR, sequencing, in situ hybridization, and serology. Genetic analysis suggests spillover from wildlife.
