aThree single infection for coronavirus OC43, one single infection each for human metapneumovirus (hMPV), parainfluenza virus (PIV)3, adenovirus, and human bocavirus (hBoV), and nine co‐infections (three RSV–hMPV, two RSV–RV, one RSV–hBoV, one RV–hMPV, one RV–hBoV, and one hBoV–PIV1).
bAge in months: p <0.05 for RSV vs. A/H1N1/2009, RV, and other virus/co‐infections, calculated with the Kruskal–Wallis test.
cFever (temperature ≥38.0°C).
dGastrointestinal symptoms: p <0.05 for virus‐negative vs. virus‐positive, calculated with the chi‐squared test.
eNegative TA: p <0.05 for A/H1N1/2009 vs. all other groups, calculated with the chi‐squared test.
