Climate change is a significant risk multiplier and profoundly influences the transmission dynamics, geographical distribution, and resurgence of vector-borne diseases (VBDs). Bangladesh has a noticeable rise in VBDs attributed to climate change. Despite the severity of this issue, the interconnections between climate change and VBDs in Bangladesh have yet to be thoroughly explored. To address this research gap, our review meticulously examined existing literature on the relationship between climate change and VBDs in Bangladesh. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, we identified 3849 records from SCOPUS, Web of Science, and Google Scholar databases. Ultimately, 22 research articles meeting specific criteria were included. We identified that the literature on the subject matter of this study is non-contemporaneous, with 68% of studies investing datasets before 2014, despite studies on climate change and dengue nexus having increased recently. We pinpointed Dhaka and Chittagong Hill Tracts as the dengue and malaria research hotspots, respectively. We highlighted that the 2023 dengue outbreak illustrates a possible shift in dengue-endemic areas in Bangladesh. Moreover, dengue cases surged by 317% in 2023 compared to 2019 records, with a corresponding 607% increase in mortality compared to 2022. A weak connection was observed between dengue incidents and climate drivers, including the El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). However, no compelling evidence supported an association between malaria cases, and Sea Surface Temperature (SST) in the Bay of Bengal, along with the NINO3 phenomenon. We observed minimal microclimatic and non-climatic data inclusion in selected studies. Our review holds implications for policymakers, urging the prioritization of mitigation measures such as year-round surveillance and early warning systems. Ultimately, it calls for resource allocation to empower researchers in advancing the understanding of VBD dynamics amidst changing climates.
气候变化是一个重要的风险倍增器，深刻影响着媒介传播疾病（VBDs）的传播动态、地理分布和再现。孟加拉国由于气候变化，VBDs 显著增加。尽管这个问题很严重，但孟加拉国气候变化与 VBDs 之间的联系尚未得到彻底探讨。为了解决这一研究差距，我们的综述仔细审查了孟加拉国气候变化与 VBDs 关系的现有文献。我们使用系统评价和荟萃分析（PRISMA）的首选报告项目，从 SCOPUS、Web of Science 和 Google Scholar 数据库中确定了 3849 条记录。最终，有 22 篇符合特定标准的研究文章被纳入。我们发现，关于本研究主题的文献是非同期的，68%的研究投资于 2014 年前的数据集，尽管最近关于气候变化和登革热关系的研究有所增加。我们指出，达卡和吉大港山区分别是登革热和疟疾研究的热点。我们强调，2023 年的登革热爆发表明孟加拉国登革热流行地区可能发生了变化。此外，与 2019 年的记录相比，2023 年的登革热病例增加了 317%，死亡率相应增加了 607%，与 2022 年相比。登革热事件与气候驱动因素之间观察到的联系较弱，包括厄尔尼诺南方涛动（ENSO）和印度洋偶极子（IOD）。然而，没有确凿的证据表明孟加拉国的疟疾病例与孟加拉湾的海表温度（SST）以及 NINO3 现象之间存在关联。我们观察到选定研究中很少纳入微气候和非气候数据。我们的综述对政策制定者具有启示意义，敦促优先采取缓解措施，例如全年监测和早期预警系统。最终，它呼吁分配资源，使研究人员能够在气候变化中增强对 VBD 动态的理解。
