Abstract
Human astrovirus (HAstV) plays an important role in human viral gastroenteritis, especially in young children and the elderly. In recent years, some novel astrovirus strains different from HAstV were reported previously and new subtypes or lineages of HAstV were found. These new strains might be responsible for the acute gastroenteritis in hospital or community, thus should be paid more attention in HAstV surveillance. This study reviewed the novel HAstVs identified recently.
Key words: Human astrovirus (HAstV), diarrhea, genotype, lineage.
