title: Prevalence and clinical profile of human bocavirus in children with acute gastroenteritis in Chengdu, West China, 2012-2013.
abstract: Viral acute gastroenteritis (AGE) is a major cause of mortality in childhood and leads to hospitalization in developing countries. Human bocavirus (HBoV) is a newly described virus associated with gastroenteritis. However, little is known about the clinical and epidemiological profile of human bocavirus (HBoV) in pediatric population in Chengdu, China. Between January 2012 and December 2013, 346 fecal samples from children admitted to hospital with acute gastroenteritis were tested for the presence of HBoV as well as other gastroenteritis viruses. Additionally, laboratory test results, clinical features and epidemiological characters were also collected to assess the correlation between HBoV and acute gastroenteritis in pediatric patients in Chengdu, China. Of the 346 tested fecal samples, 60 (17.34%) were positive for HBoV. The rate of co-detection of HBoV with other gastroenteritis viruses was 43.33% (26/60). HBoV was most detected in the summer/early fall months. Sequence analysis of the VP1/VP2 gene showed that both HBoV1 and HBoV2 circulated in Chengdu, China. No obvious difference was found between the clinical features of the HBoV1 mono-detected patients and HBoV2 mono-detected patients. Besides, in diarrheic children, positive correlation was found between detection of HBoV and diagnose of respiratory disease. Furthermore, blood cells were detected more frequently in fecal samples of patients with HBoV mono-detected. Though HBoV was detected frequently in Children with diarrhea in Chengdu, no statistical association was found between HBoV and disease severity.
