[Human bocavirus and its current epidemic status in China].

Human bocavirus (HBoV) is classified in the family of parvovirdae, genus bocavirus. Besides parvovirus B19 and human parvovirus 4 (PARV4), HBoV isone of the parvoviruses currently known to infect and cause illness in human. So far, four different HBoVs (HBoV1-4) have been successively reported. The incidence of HBoVs infection varies widely, the clinical presentations of patients are different, and HBoVs are often co-detected with other pathogens. There are already quite a few report of HBoVs infection, and this article reviews and discusses the biological characters, epidemic characters, pathogenic mechanism, phylogenetic analyses of HBoVs and the epidemiological situation in China.
