Molecular characterization of respiratory syncytial viruses circulating in a paediatric cohort in Amman, Jordan.

ABSTRACT: Respiratory syncytial viruses (RSVs) are an important cause of mortality worldwide and a major cause of respiratory tract infections in children, driving development of vaccine candidates. However, there are large gaps in our knowledge of the local evolutionary and transmission dynamics of RSVs, particularly in understudied regions such as the Middle East. To address this gap, we sequenced the complete genomes of 58 RSVA and 27 RSVB samples collected in a paediatric cohort in Amman, Jordan, between 2010 and 2013. RSVA and RSVB co-circulated during each winter epidemic of RSV in Amman, and each epidemic comprised multiple independent viral introductions of RSVA and RSVB. However, RSVA and RSVB alternated in dominance across years, potential evidence of immunological interactions. Children i
