CSRV common seasonal respiratory virus, Ev/Rh Enterovirus/rhinovirus, hMPV human metapneumovirus, ADV adenovirus, BCV bocavirus, RSV respiratory syncytial virus, hIV human influenza virus, HPiV human parainfluenza virus, HCoV human coronavirus, URTD upper respiratory tract disease, LRTD low respiratory tract disease, P1 period 1, P2 period 2, P3 period 3.
aThe percentages of each CSRV episode were calculated using the total number of CSRV isolated as denominator.
