PCV2 is a ubiquitous virus in domestic pig and wild boar, both in countries where porcine circovirus diseases (PCVDs) have or have not been described.

Postweaning multisystemic wasting syndrome (PMWS) was first described by Harding and Clark at the Western Canadian Association of Swine Practitioners’ (WCASP) conference in 1996

Porcine Circovirus type 2 (PCV2) is a ubiquitous virus infecting domestic pigs and wild boars.

Porcine circovirus type 2 (PCV2)–associated disease (PCVAD) continues to be an important differential diagnosis on pig farms in the United States and worldwide.

As swine producers continue to battle to protect their herds from long-standing diseases and emerging threats, Boehringer Ingelheim Vetmedica, Inc., (BIVI) remains committed to supporting innovative research and product development initiatives that lead to effective solutions.

In the late 1990's an apparantly noval porcine circovirus (PCV)-like virus was detected worldwide in diseased and nondiseased pigs.

This review paper concentrates on the aetiology, diagnosis, and pathological aspects of postweaning multisystemic wasting syndrome (PMWS). PMWS was first recognized in Canada in 1996 as a new emerging disease which caused wasting in postweaned pigs.

Clinical expression of porcine circovirus 2 (PCV2) infection in swine may result in several distinct syndromes and diseases including post-weaning multisystemic wasting syndrome (PMWS), porcine dermatitis and nephropathy syndrome (PDNS), reproductive failure, porcine respiratory disease complex, granulomatous enteritis, necrotizing lymphadenitis, and possibly exudative epidermitis.
