Abstract
The Alongshan virus (ALSV), classified within the Flaviviridae family and belonging to the Jingmenvirus group, is a segmented RNA virus that was first identified in China in 2017. Since then, it has been reported in several Eurasian countries. Although no confirmed fatal cases have been documented, the potential public health risks associated with ALSV are significant and warrant serious attention. The emergence of ALSV has not only broadened the array of tick-borne diseases but has also enriched the research landscape surrounding segmented flaviviruses. Despite these advancements, our understanding of ALSV is still nascent, and its complex infection pathways remain largely unexplored. This review seeks to offer an in-depth examination of ALSV, addressing its biological properties, molecular features, epidemiological data, clinical presentations, and diagnostic methodologies. Our objective is to promote progress in the formulation of preventive, diagnostic, and therapeutic measures for this emerging segmented flavivirus.
