RSV distribution
Annual positivity rates of RSV infection varied across the study period. Positivity rates ranged from 1.2% (2006) to 22.9% (2010) with an overall prevalence rate of 11.8% (122/1036). The highest positivity rates were observed in 2010 and 2011, respectively. RSV infection was observed all throughout the year, however increased positivity rate among specimens collected during the second half of the year (June to December). The study showed that 58.2% (71/122) of the RSV positive specimens belonged to the subgroup RSV-A while 40.1% (49/122) to RSV-B. Co-infection between both RSV subgroups were observed in 1.6% (2/122) of the samples. Co-circulation between both subgroups were observed for the period of 2007-2015, with higher number of RSV-A related cases (50.0-100.0%).
