Porcine Circovirus type 2 in Vietnam: ruminations on a puzzling swine virus
Author: Do Tien Duy, Lam Thi Thu Huong and Juliet E Bryant
Porcine circovirus type 2 (PCV2) emerged as a major swine pathogen in the 1990s, and is now considered one of the most significant production diseases impacting the global swine industry. Determining the causal role of PCV2 in syndromic swine disease and epizootics has proven complicated and controversial, although the emergence phenomena appears linked to modern intensive production systems of western countries. PCV2 vaccination is now routinely used in developed countries to mitigate impaired production efficiencies and economic losses associated with endemic PCV2 transmission. In Vietnam, the epidemiology of PCV2 remains poorly understood but is gaining increased attention from the veterinary community and increasingly sought as a differential diagnosis in outbreak situations. This review discusses current knowledge of PCV2 epidemiology as it relates to the swine sector of Vietnam, and addresses potential direct and indirect implications of PCV2 infections for human health
