Gastrointestinal Illness

In general, an outbreak of acute gastroenteritis in a facility is defined as the presence of more diarrhea or vomiting than would usually be expected in the facility, or in a particular unit, for that time of year. A simple threshold for when to suspect an acute gastroenteritis (AGE) outbreak is when three or more residents and/or staff experience AGE symptoms within a 72-hour period and have geographic commonality (i.e., same wing, unit, floor).

A specific case definition for norovirus could be: Acute onset of vomiting and/or diarrhea (three or more loose stools in a 24-hour period) in a resident or staff member and whose symptoms have no other apparent cause.
