Human parvovirus B19 (B19 virus) is one of the two parvoviruses that cause human diseases. As an important pathogen to humans, it causes infectious erythema in children, acute aplastic anemia, fetal edema and death. In this review, we focus on the recent advances in the molecular virology of B19V, such as viral genotypes, viral receptor, genomic features and viral replication, viral transcription and post-transcription regulation, viral nonstructural and structural protein features and functions, viral diagnosis and antiviral agents, to provide reference for further study of B19 pathogenesis mechanisms, treatment and diagnostic strategies.
人细小病毒 B19 (Human parvovirus B19，简称B19 病毒)，是目前为止已知能够感染并引起人类疾病的两种细小病毒科成员之一。B19 病毒作为一种重要病原，能够引起如儿童传染性红斑、急性再障危象、胎儿水肿甚至死胎等疾病。文中从B19 病毒基因型、病毒受体、基因组结构特点与复制、病毒转录与转录后调控、病毒非结构和结构蛋白特点与功能以及病毒诊断及抗病毒药物研究策略6 个方面来综述B19 病毒的最新研究进展，以期为B19 病毒致病机制的深入研究与治疗诊断策略的制定提供参考。.
