Genotypic variations and clinical implications of JEV-associated peripheral nerve injury: a commentary on multicenter findings from high-endemic regions

We read with great interest the recent article by Wang et al. on peripheral nerve injury (PNI) associated with Japanese encephalitis virus (JEV) infection in high-endemic regions of China. The study provides important insights into the significant relationship between JEV infection and PNI, particularly highlighting clinical manifestations such as acute flaccid paralysis and respiratory muscle paralysis. While we commend the authors' work, we suggest caution in interpreting the findings due to several limitations. First, genotype-specific differences, notably between GIb and GIII strains, may influence disease severity, clinical progression, and prognosis, warranting further investigation for personalized management. Second, although adjustments were made for certain demographic and epidemiological variables, additional confounders such as vaccination status, environmental conditions, and socioeconomic factors should be incorporated to strengthen the robustness of future analyses. Third, reliance on surveillance data introduces potential biases due to incomplete or inaccurate reporting, especially in rural or underserved populations. Enhanced data collection methods, including digital health tools and standardized questionnaires, could improve accuracy and comprehensiveness. Beyond methodological considerations, the study underscores the importance of early diagnosis, biomarker development, and multidisciplinary collaboration in mitigating neurological complications of JEV. Strengthening vaccination coverage, particularly in remote regions, and expanding health education are also critical to reducing disease burden. Overall, this research advances understanding of JEV-associated PNI and highlights avenues for future studies to refine diagnostic, preventive, and therapeutic strategies that will improve long-term patient outcomes.
