Respiratory Syncytial Virus Co-infection in the Era of COVID-19 Pandemic

ABSTRACT

Background:Respiratory syncytial virus (RSV), a known viral pathogen of paediatric age group is now an emerging cause of severe respiratory illness in adults. In the current pandemic, a new strain of Corona virus named SARS CoV -2, has emerged as the causative agent. Both these viral infections have similar clinical presentation and needs to be differenti- ated for appropriate management. Methods:In this cross-sectional study, nasopharyngeal swab samples from individuals with severe acute respiratory infections were tested for SARS CoV-2 and RSV A and B by multiplex real time polymerase chain reaction (PCR). Results:We analysed 100 consecutive samples collected from patients of SARI and the same were subjected to RT-PCR. SARS CoV2 was detected in 35% samples whereas 22% patients were found positive for RSV. 5% samples showed co-infection of RSV and SARS CoV2. RSV B (19%) found to be more prevalent than RSV A (2%). 17% symp- tomatic patients were detected with RSV but not SARS CoV2. [Formula presented] Conclusions:RSV infection in adults should not be under rated. The study highlights the importance of identifying other respiratory pathogens for specific management during current COVID-19 pandemic
