For respiratory disease surveillance programs using qRT-PCR that aim to maximize sensitivity for a large number of viruses, collecting combined NP and OP specimens would be the most effective approach. To evaluate the comparative yields of NP and OP swabs in detecting key respiratory viruses by real-time RT-PCR (qRT-PCR), we conducted a prospective study using paired NP and OP specimens from patients at two respiratory disease surveillance sites in Kenya. NP and OP specimens from each patient were separately tested by singleplex qRT-PCR for eight viral pathogens: adenovirus, influenza A virus, influenza B virus, human metapneumovirus (hMPV), parainfluenza viruses (PIV) 1-3, and respiratory syncytial virus (RSV).	./cache/cord-260572-vd65ygtm.txt	./txt/cord-260572-vd65ygtm.txt
