A modified Vesikari severity score (MVSS) is a useful research tool for assessing severity of acute gastroenteritis. We present a MVSS for studies in which a follow-up assessment of symptoms cannot be obtained. The MVSS significantly correlated with other markers of severity, including illness duration and work and school absenteeism.
