*URI, upper respiratory tract infection.
†Data are presented as no. of physician visits/child. Because of our prospective study design, many children had >1 URI episode during the follow-up period, and some had >1 physician visit/URI episode. One nasopharyngeal swab sample was taken at each physician visit.
