The Alongshan virus: A comprehensive review of its pathogenic characteristics, epidemiology, and detection strategies

Abstract

Alongshan virus (ALSV) is an emerging tick-borne segmented RNA virus belonging to the Flaviviridae family, first identified in Northeastern China in 2017. ALSV is currently classified within the Jingmenvirus group, which includes other segmented flavi-like viruses. Since its discovery, ALSV has been detected in various regions, including China, Russia, and several European countries, highlighting its expanding geographic distribution. This review summarizes the latest research progress on ALSV, focusing on its pathogenic characteristics, pathogenicity, epidemiological features, and detection methods. ALSV exhibits a segmented genome, unique structural and nonstructural proteins, and potential neurotropism, with clinical symptoms resembling other tick-borne diseases. Detection methods, including nucleic acid detection and high-throughput sequencing, have advanced ALSV research, though challenges remain in standardization and clinical application. Understanding ALSV's ecological characteristics, transmission mechanisms, and public health impact is crucial for developing effective prevention and control strategies. This review provides valuable insights for healthcare institutions and policymakers to mitigate ALSV's risks.
