Tick-Borne Encephalitis Virus (TBEV): Epidemiology, Diagnosis, Therapeutic Approaches and Some Molecular Aspects—An Updated Review

Tck-borne encephalitis virus (TBEV) is a significant public health concern, particularly in rural regions, like the Caucasus, where tick-borne diseases are prevalent. The review contains comprehensive data on TBEV circulation in the Caucasus region, demonstrating TBE cases in the North Caucasus and Georgia, as well as the identification of new endemic foci in Armenia and Azerbaijan, highlighting the need for further epidemiological studies and surveillance in the region. This review provides an updated overview of TBEV, encompassing its status, subtypes, life cycle and circulation in nature, epidemiology, new approaches to TBE treatment and diagnostics, and recent insights into molecular aspects. Understanding the complexities of TBEV transmission, clinical manifestations, and advancements in diagnostic techniques is crucial for effective management and control strategies. Furthermore, exploring the molecular mechanisms underlying TBEV pathogenesis and host interactions can offer valuable insights for developing novel therapeutics and preventive measures. This comprehensive review aims to consolidate recent research findings and enhance our understanding of TBEV, ultimately contributing to improved public health interventions and patient outcomes.
