Number of cases of rotavirus around the world

Rotavirus is the leading cause of severe diarrhea (gastroenteritis) in children throughout the world. About 95% of children contract the infection by 5 years of age.

Mortality due to rotavirus infection is much higher in developing countries. The World Health Organization estimates that 453,000 children aged less than 5 years died in 2008 from vaccine-preventable rotavirus infections. Globally, these rotavirus deaths account for approximately 5% of all child deaths.

Disease outbreaks demonstrate a seasonal pattern in temperate climates, where the disease is more pronounced during drier and cooler months.
