aAn episode can be codetected with ≥1 other virus(es).
bEpisode numbers (row percentage) for each type of infection that was detected with each enteric virus.
cSapovirus detection included genogroups I, II, IV, and V.
dNineteen of 23 (82.6%) human rotavirus–positive swabs were from live attenuated multivalent human-bovine reassortant vaccine strains (RotaTeq, Merck and Co) [23].
eSymptom diaries not recorded by parents at the time a PeV swab tested positive.
