Circoviruses are small, non-enveloped icosahedral viruses that are emerging as important pathogens of several animal species. Porcine circovirus type 2 (PCV-2) was first discovered in Canada in 1991 as the infectious agent for post-weaning multisystemic wasting syndrome (PMWS), a progressive disease that occurs in piglets. Since its original discovery, PCV-2 has been identified world-wide as an important pathogen causing significant economic losses in swine herds. Similarly, the etiological agent of infectious chicken anemia, chicken anemia virus (CAV) has also been shown to be a circovirus and controlling outbreaks of this virus

圆环病毒是一种小型无包膜二十面体病毒，是几种动物的重要病原体。猪圆环病毒2型（PCV-2）于1991年在加拿大首次发现，是断奶后多系统衰竭综合征（PMWS）的病原体，PMWS是一种发生在仔猪中的进行性疾病。PCV-2自首次发现以来，已在世界范围内被确定为造成猪群重大经济损失的重要病原体。同样，鸡传染性贫血病的病原鸡贫血病毒（chicken anemia virus，CAV）也被证明是一种圆环病毒，并控制了这种病毒的爆发
