Rotaviruses, noroviruses, adenoviruses, and astroviruses are known to cause viral gastroenteritis. [26] Rotavirus is the most common cause of gastroenteritis in children, [25] and produces similar rates in both the developed and developing world. [20] Viruses cause about 70% of episodes of infectious diarrhea in the pediatric age group. [13]

Sapovirus is a genetically diverse genus of single-stranded positive-sense RNA, non-enveloped viruses within the family Caliciviridae. [1] [2] Together with norovirus, sapoviruses are the most common cause of acute gastroenteritis (commonly called the "stomach flu" although it is not related to influenza) in humans and animals.
Depending on the cause of the inflammation, symptoms may last from one day to more than a week. Gastroenteritis caused by viruses may last one to two days.
