Vesikari Scoring System assesses the following symptoms: duration of diarrhea (days), maximum number of diarrheal stools/24 hours, duration of vomiting (days), maximum number of vomiting episodes/24 hours, fever and dehydration.
Since the typical inpatient phase was four days in length, the duration of diarrhea scoring was modified to fit this time frame.

Score 1 was based on a subset of symptoms including: elevated oral temperature, myalgia, nausea, abdominal cramps, bloating, diarrhea, and vomiting.
Score 2 was based on all Score 1 symptoms plus fatigue/malaise, chills, and loss of appetite.
Total Score 1=0 to 20 and Total Score 2=0 to 29.
