title: [Comparison of the number of Norovirus genome copies in patients and healthy persons].
abstract: In viral gastroenteritis outbreaks occurred by Norovirus (NV), NV was detected not only from patients but also from healthy persons who have taken the same food, and also detected from healthy staff members working at community places such as hospital, school and nursing home. The number of fecal NV genome copies of patients, healthy persons and food handlers are examined by real-time PCR method, to investigate foodborne gastroenteritis and person to person transmission outbreaks. There is no significant difference on the number of NV genome copies in feces between patients, and NV-detected healthy persons. Those result indicate asymptomatic carrier of NV who were working as food handlers or staff members at community places will become an origin of food-borne gastroenteritis or person to person transmission outbreaks.
