UST, unsubtypeable and presumed novel H1N1; Adeno, adenovirus; coronaviruses 229E, NL63 and HKU-1; E/R, enterovirus/rhinovirus group; hMPV, human metapneumovirus; P1, parainfluenza virus 1; P2, parainfluenza virus 2; P3, parainfluenza virus 2; RSV, respiratory syncytial virus. A total of 2715 samples were tested by xTAG RVP assay. Number (%): number identified as positive for virus (percentage of total specimens). Mixed infections: virus (number detected).
