沙粒病毒(Arenaviruses,下称沙病毒)是一组RNA病毒,包括10种形态相似、血清学相关的病毒,现已发现有4种可引起人类疾病(表1)。由于沙病毒引起的疾病与流行性出血热有些相似,尤其是拉沙热尚可在人群中传播,因此对沙病毒的研究具有一定的意义。本文将近年来有关沙病毒及其引起的疾病的研究进展综述于下。 Arenaviruses are a group of RNA viruses, including 10 morphologically similar, serologically related viruses, and four have been found to cause human disease (Table 1). Due to SARS-like diseases and epidemic hemorrhagic fever is somewhat similar, especially Lassa fever can still be spread in the crowd, so the research on the sand virus has some significance. In this paper, recent progress in research on sand-borne virus and its related diseases is summarized below.
