Porcine circovirus type 3 (PCV3) is a newly emerging porcine circovirus that infects pig populations worldwide. In this study, we investigated the prevalence of PCV3 in Taiwan and analyzed the phylogenetic relationships between the Taiwanese PCV3 strains and those from other countries. A total of 463 clinical specimens from sick pigs were collected in 2016-2019 and analyzed for PCV3 by PCR. The positivity rate for PCV3 was 10.6% in 2016, increasing markedly to 34.78% in 2019. A phylogenetic analysis based on full-length genomic sequences of PCV3 divided the PCV3 strains into three clades, with the Taiwanese strains in clade 1.
