ABSTRACT
Human bocavirus (HBoV) is a parvovirus whose association with respiratory disease is currently under investigation. OBJECTIVE:
To determine HBoV prevalence in children with lower acute respiratory infection.METHODS:
We investigated HBoV in 433 nasopharyngeal aspirates collected in 2007-2009 from children 0 to 5 years old hospitalized with bronchiolitis or pneumonia in Córdoba, Argentina.RESULTS:
The general prevalence of HBoV was 21.5 percent and the positive cases (HBoV+) were more frequent during winter and spring. The mean age of HBoV+ patients was 6.9 months, with 87.1 percent of the detections corresponding to infants less than 1 year old (among which the prevalence of HBoV was 26.3 percent in patients < 3 months of age, 22.1 percent in 3 to 6 months, 25.3 percent in 6 to 9 months, and 18.8 percent in 9 to 12 months). The sequence analysis of the NP1 coding region of 15 isolates showed that all isolates from Cordoba were HBoV1 which exhibited a homology of nearly 100 percent both among themselves and with the originally discovered virus from 2005.CONCLUSION:
Overall, our results indicate that HBoV is a significant pathogen that contributes to acute respiratory infection both on its own and during coinfection with other viruses.
