[20] Viruses cause about 70% of episodes of infectious diarrhea in the pediatric age group. [13]
NSP4 is a viral enterotoxin that induces diarrhoea and was the first viral enterotoxin discovered. [56] It is a viroporin that elevates cytosolic Ca 2+ in mammalian cells. [57] NSP5 is encoded by genome segment 11 of rotavirus A. In virus-infected cells NSP5 accumulates in the viroplasm. [58]
Infectious diarrhea is frequently referred to as gastroenteritis. [30] Norovirus is the most common cause of viral diarrhea in adults, [31] but rotavirus is the most common cause in children under five years old.

Human astroviruses are associated with gastroenteritis in children and immunocompromised adults. [32] 2–8% of acute non-bacterial gastroenteritis in children is associated with human astrovirus. These viral particles are usually detected in epithelial cells of the duodenum. [4]
Gastroenteritis can be caused by viral, bacterial, or parasitic infections. Common routes of infection include: Food; Contaminated water; Contact with an infected person; Unwashed hands [2] Fifty to seventy percent of cases of gastroenteritis in adults are caused by noroviruses (genus Norovirus, family Caliciviridae). This virus is highly ...
