1: Numbers in parenthesis are percentage of total nasopharyngeal aspirates.
2: Only one virus detected. Numbers in parenthesis are percentage of positive samples for that virus.
3: Numbers in parenthesis are percentage of samples positive for the specific virus in the column co-infected with the virus(es) in the rows.
4: Previously-tested by immunofluorescence assay.
5: Previously-tested previously by nested-PCR.
6: Including previously-tested by immunofluorescence assay (Influenza A, RSV, PIV, adenovirus) and nested-PCR (hMPV).
