PRV1 was first detected in deceased pigs from Hong Kong in 2013. It has
since been detected in the USA, Chile and most recently in Hungary.
Information on the pathogenicity and global spread is sparse, however it
has been speculated to play a role in the porcine respiratory disease
complex. In an effort to investigate the porcine virome, we screened 53
pig samples from 29 farms using SMg within the Dutch/German border
region. In five farms we detected PRV1. qPCR confirmed the presence of
the virus in 2 of these farms and found an additional 6 positive farms.
Phylogenetic analysis found the closest match to the first detected PRV1
strain in Hong Kong. The Dutch/German region represents a major area of
pig farming within Europe and could provide important information on the
characterization and circulation of porcine viruses, such as PRV1.
Together with the recent detection of PRV1 in Hungary, these findings
suggest widespread of PRV1 in Central Europe, highlighting the need for
further research on persistence, pathogenicity and transmission in
