Respiratory syncytial virus (RSV) is a common cause of acute respiratory disease worldwide, especially in young children. The World Health Organization (WHO) has initiated an RSV Surveillance Pilot program that aims to perform worldwide RSV surveillance, requiring the development of reliable and rapid molecular methods to detect and identify RSV. A duplex real-time RT-PCR assay developed for simultaneous detection of both A and B subtypes of RSV was included as part of this program. This duplex assay targeted a conserved region of the RSV polymerase gene and was validated for analytical sensitivity, specificity, reproducibility and clinical performance with a wide range of respiratory specimens. The assay was highly specific for RSV and did not react with non-RSV respiratory pathogens, including the SARS-CoV-2 virus.
