Abstract

In 2009 to 2010, there was a marked increase in the number of infections with highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) in China. Through phylogenetic analysis, we show that viruses from this outbreak originated from a single recombination event, illustrating the potential importance of this process for disease emergence.
