Age-specific differences in influenza A epidemic curves: do children drive the spread of influenza epidemics?

abstract：:During the period from September 8 to October 2, 1970, 44 of the 120 children and 78 of 141 adults questioned at the Children's Asthma Research Institute and Hospital experienced gastroenteritis characterized by nausea, vomiting, and fever and/or chills. Diarrhea was rare in children (4.5%) and common in adults (74%)....
