Porcine bocavirus was identified in 2009 and fell into the bocavirus，the co-infection of which with other viruses was serious clinically，leading to gastrointestinal and respiratory diseases in pigs. But its pathogenesis was still unknown，as it had not been successfully isolated and purified in vitro cell lines，and corresponding vaccines were still under development. Its detection rate was increasing year by year，posing a huge threat to pig industry and a great challenge to public health as human could be infected across the species barrier. In the paper，the etiology，epidemiology，pathogenesis，diagnosis and detection，prevention and control measures concerning the virus were summarized，with a view to providing a reference for future efforts for fighting against the infection and researches.
