Bats have been identified as reservoir hosts for an exceptional diversity of viruses, including multiple taxa of high zoonotic concern. Over a hundred bat species inhabit Vietnam, which, combined with significant biodiversity, carry high risk of zoonotic spillover due to dense human–animal interfaces, extensive wildlife trade, and proximity to recent outbreak epicenters. This review systematically synthesizes data on the bat virome in Vietnam and neighboring Southeast Asian countries, assessing viral diversity, host species involvement, and zoonotic potential. By prioritizing virus groups with established zoonotic capacity and pandemic potential, the systematic search identified studies reporting viruses from 32 families across 13 bat families. Based on the WHO 2024 risk classification, seven of these viral families were categorized as high-risk, three as medium-risk, and twelve as low-risk. The comparatively higher viral diversity reported in neighboring countries suggests that the current study likely represents an underestimation of the true virome present in Vietnamese bat populations. We emphasize the urgent need for expanded virological studies integrating metagenomic sequencing, serological surveys, and ecological modeling to improve early detection of emerging threats, as the comparatively higher viral diversity reported in neighboring countries suggests existing research likely represents an underestimation of the true virome present in Vietnamese bat populations. Strengthening regional collaboration is critical for establishing proactive pandemic prevention strategies in this high-risk zoonotic hotspot.
