PCV2 – a silent threat

Porcine circovirus type 2 (PCV2) is such a ubiquitous virus in swine production systems that up to 100% of pigs are seropositive for PCV2 at slaughter. It is associated with Porcine Circovirus Diseases (PCVD) and is a significant contributor to the Porcine Respiratory Disease Complex (PRDC).

Often present as subclinical infections during the growing phase, PCV2 silently threatens with poor growth performance in apparently healthy pigs, which may then intermittently shed the virus, keeping it circulating within the herd. PCV2 is present in pigs regardless of PCVD severity in the farm, and there are always more subclinical pigs than clinical pigs.1
