Increasing Rates of Gastroenteritis Hospital Discharges in US Adults and the Contribution of Norovirus, 1996–2007

Abstract

Gastroenteritis hospitalizations are increasing, and we estimate that norovirus is the cause of 10% of cause-unspecified and 7% of all-cause gastroenteritis discharges. Norovirus should be routinely considered as a cause of gastroenteritis hospitalization.
