Abstract
- Objective. To describe the epidemiology of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) in Colombia from 2000-2011, including seasonal trends. Methods. Nasopharyngeal aspirates and/or throat swabs from 14 870 patients with acute respiratory infections (ARI) were studied. Two subgroups were analyzed using molecular biology techniques. The first consisted of 264 RSV indirect fluorescence assay (IFA)-positive samples, the second of 264 RSV IFA-negative samples. RSV and hMPV were detected using reverse transcription polymerase chain reaction (RT-PCR). Results. 2 799 samples (18.8%) contained a respiratory virus. RSV was detected by IFA in 1 333 samples (8.9%). RSV was detected by RT-PCR in 192 samples from the RSV IFA-positive subgroup and in 25 samples from the RSV IFA-negative subgroup. hMPV was detected in eight samples from the RSV IFA-positive subgroup and in 11 samples from the RSV IFA-negative subgroup. Among the RSV infections, subtype A was dominant in two-year intervals, subtype B was dominant in one-year intervals. 85.3% of RSV and 74% of hMPV infections occurred in children younger than 5 years old. RSV and hMPV infections were associated with rainy seasons. Co-infection with RSV A and RSV B was detected in two patients. Five cases of co-infection with RSV and hMPV were detected. Conclusions. This report is the first to examine the epidemiology of ARIs in Colombia, with an emphasis on RSV and hMPV. The samples studied here were obtained over a 12-year period and represent all age groups and both genders. [ABSTRACT FROM AUTHOR]
