hRV-B sequenced by using nested PCR	56 (4.6%)	2 (0.2%)
hRV-C sequenced by using nested PCR	46 (3.7%)	3 (0.2%)

^∗Influenza A; influenza B; respiratory syncytial virus; parainfluenza viruses 1, 2, and 3; and human metapneumovirus. There were 8 samples that contained hRV and another virus, 5 of which were respiratory syncytial virus, and there were single occurrences of parainfluenza 1, parainfluenza 3, and metapneumovirus.
