Dengue is one of the most widespread and fatal arboviral infections in the world. Early detection of dengue virus (DENV) is essential to prevent the spread of the disease and provide an immediate response. The lateral flow immunoassay (LFIA) systems are low-cost, rapid, sensitive, targeted, and straightforward detection, which is an ideal early detection candidate for point-of-care testing (POCT) in dengue-affected areas. However, current commercial LFIA kits cannot fully satisfy the sensitivity, specificity, serotype differentiation, and multiplex detection requirements. Therefore, various strategies have been applied to optimize the LFIA for DENV detection, including label material improvement, optical enhancement and novel structure design. In this review, we comprehensively presented the snapshot of dengue, the principle of LFIA, and recent progress in the LFIA optimization for dengue diagnoses. Furthermore, this review also discusses insights into the prospect of LFIA dengue diagnostic methods, such as microfluidics, multiplex design, nucleic acid-typed probes and smartphone-assisted result analysis.

侧向层析免疫测定法 (LFIA) 用于登革热诊断的最新进展与展望
登革热是世界上分布最广、最致命的虫媒病毒感染之一。早期发现登革热病毒 (DENV) 对于防止疾病传播和提供即时应对措施至关重要。侧向层析免疫测定 (LFIA) 系统具有低成本、快速、灵敏、靶向和直接的检测方法,是登革热受影响地区即时检测 (POCT) 的理想早期检测候选者。然而,目前的市售 LFIA 试剂盒不能完全满足灵敏度、特异性、血清型鉴别和多重检测要求。因此,已经应用了各种策略来优化 DENV 检测的 LFIA,包括标记材料改进、光学增强和新颖的结构设计。在这篇综述中,我们全面介绍了登革热的快照、LFIA 的原理以及 LFIA 优化登革热诊断的最新进展。此外,本综述还讨论了对 LFIA 登革热诊断方法前景的见解,例如微流体、多重设计、核酸型探针和智能手机辅助结果分析。
