What is the most common cause of gastroenteritis?
Gastroenteritis
It is estimated that there were two billion cases of gastroenteritis that resulted in 1.3million deaths globally in 2015.[6][7] Children and those in the developing world are most commonly affected.[15] As of 2011, in those less than five, there were about 1.7billion cases resulting in 0.7million deaths,[16] with most of these occurring in the world's poorest nations.[17] More than 450,000 of these fatalities are due to rotavirus in children under 5years of age.[10][77] Cholera causes about three to five million cases of disease and kills approximately 100,000 people yearly.[30] In the developing world, children less than two years of age frequently get six or more infections a year that result in significant gastroenteritis.[17] It is less common in adults, partly due to the development of acquired immunity.[18]
