An outbreak of acute gastroenteritis in a kibbutz in southern Israel, characterized by diarrhea, fever, vomiting, and abdominal pain, involved 32 kibbutz members of all ages. Nineteen percent of the children and 3.5% of the adults were ill. Transmission of the illness occurred in direct proportion to the degree of close contact, involving first infants, then mothers and nursery staff, and only later youngsters, adolescents, and fathers. Stool samples obtained from 32 kibbutz members with clinical illness and from 44 asymptomatic close contacts were examined for the presence of rotavirus antigen. Fifty‐six percent of symptomatic members were positive for rotavirus antigen as compared with 4.5% of asymptomatic close contacts. Positivity of stool samples correlated inversely with the number of days elapsed after onset of illness until the sample was obtained. Serologic studies carried out on acute and convalescent sera of symptomatic and asymptomatic subjects further supported a rotavirus etiology for the outbreak. RNA profiles of stool sample extracts obtained by polyacrylamide gel electrophoresis and silver staining indicate that one electropherotype may have been responsible for the outbreak.
