Acute gastroenteritis is a diarrheal disease of rapid onset.
Viruses are one of the common causes of gastroenteritis.
Rotavirus, enteric adenovirus serotypes 40 & 41, astrovirus and calicivirus (eg "Norwalk-like" virus) are the established viral agents causing gastroenteritis.
Rotavirus is the most common pathogen causing diarrhea in patients 3-24 months old.
Patients <3 months old are protected by maternal rotavirus antibodies that are passed transplacentally and possibly by breastfeeding.
Transmission is through fecal-oral route.
Incubation period may vary from 1-10 days depending on the causative agent.
