呼吸道感染新发病毒的流行病学

Epidemiologicai reseach on the newly discovered viruses in respiratory infection

急性呼吸道感染（ARTI）是人类最常见的传染性疾病之一，90％以上的ARTI是由病毒引起，目前仍有大约30％的ARTI病原不能确定。近年来，一系列新出现的病原体被发现，如人偏肺病毒、人博卡病毒、人冠状病毒NL-63和HKUI、WU和KI多瘤病毒及Saffold心病毒等。此文就呼吸道感染新发病毒的流行病学研究进展进行综述。

Acute respiratory tract infection （ARTI） is one of the most common infectious diseases in the world. About 90% of pathogens causing ARTI are viruses, while 30% of ARTI pathogens remain unidentified. Recently, many newly discovered respiratory viruses including human metapneumovirus, human boeavirus, human coronavirus NL-63 and HKU1, polyomavirus WU and KI and saffold cardiovims have been identified to cause ARTI. This article reviews epidemiology of the newly discovered viruses.
