Abstract:
Objective To investigate the status and clinical and epidemiological characteristics of human metapneumovirus (hMPV) and human bocavirus (HBoV) infections in children with acute respiratory tract infections (ARTIs) in Taiyuan. Methods A total of 549 children with ARTIs from November 2012 to May 2013 and November 2013 to May 2014 were recruited. The pharyngeal swab specimens were collected. The hMPV and HBoV were detected by using real-time PCR. Results In 549 children, 56 children (10.2%) were hMPV positive on swab specimens, 15 children (2.7%) were HBoV positive on swab specimens. The detection rates of hMPV and HBoV in November 2012 to May 2013 were 12.3%and 2.0%, respectively, and in November 2013 to May 2014 were 6.5%and 4.0%, respectively. The detection rate of hMPV was signiifcantly different between two periods (P<0.05), while the detection rate of HBoV has no signiifcant difference between two periods. In different months, the detection rate of hMPV and HBoV showed no signiifcant difference. The highest detection rates of hMPV and HBoV were all in children younger than two years old. The highest detection rate of hMPV was in children with asthmatic bronchitis or bronchiolitis. Conclusion In Taiyuan, during the monitoring periods, the ARITS are associated with childhood hMPV and HBoV infection especially in infants and toddlers. hMPV is one of the most important pathogens in infants and toddlers with wheezing.
