人星状病毒(Human Astrovirus,HAstV)是1975年由Appleton和Higgins用电镜检测英国一起腹泻疫情的粪便标本时首次发现,由于病毒颗粒表面呈星形,此后被Madeley和Cosgrove命名为星状病毒。世界大部分地区均有HAstV感染的报道,已证实它是引起婴幼儿、老年人及免疫低下者腹泻的重要
Human Astrovirus (HAstV) was first detected in 1975 by Appleton and Higgins using electron microscopy to detect a diarrhea epidemic in the United Kingdom.

Reports of HAstV infection in most parts of the world have confirmed that it is important for causing diarrhea in infants and young children, the elderly and those with immunocompromised conditions
