The literature of Porcine Circovirosis, including the main data on epidemiology and clinical, macroscopic and microscopic alterations of the infection of swine by Porcine Circovirus type 2 (PCV-2), is reviewed. There are various forms of infection: the [Porcine] Postweaning Multisystemic Wasting Syndrome (PMWS), Porcine Congenital Tremor, Porcine Dermatitis and Nephropathy Syndrome, and other associated or correlated diseases as the Porcine Reproductive and Respiratory Syndrome, Proliferative Necrotizing Pneumonia, and reproductive disorders. As PMWS already has been reported from southern Brazil and from the state of Rio de Janeiro, the objective of this review is to draw attention to the implications of this virosis for swine production in Brazil and its economical importance.
