BACKGROUND & OBJECTIVES: Dengue is a climate-sensitive infectious disease. Climate-based dengue early warning may be a simple, low-cost, and effective tool for enhancing surveillance and control. Scientific studies on climate and dengue in local context form the basis for advancing the development of a climate-based early warning system. This study aims to review the current status of scientific studies in climate and dengue and the prospect or challenges of such research on a climate-based dengue early warning system in a dengue-endemic country, taking Malaysia as a case study.
We reviewed the relationship between climate and dengue derived from statistical modeling, laboratory tests, and field studies. We searched electronic databases including PubMed, Scopus, EBSCO (MEDLINE), Web of Science, and the World Health Organization publications, and assessed climate factors and their influence on dengue cases, mosquitoes, and virus and recent development in the field of climate and dengue.
RESULTS & DISCUSSION: Few studies in Malaysia have emphasized the relationship between climate and dengue. Climatic factors such as temperature, rainfall, and humidity are associated with dengue; however, these relationships were not consistent. Climate change projections for Malaysia show a mounting risk for dengue in the future. Scientific studies on climate and dengue enhance dengue surveillance in the long run.
It is essential for institutions in Malaysia to promote research on climate and vector-borne diseases to advance the development of climate-based early warning systems. Together, effective strategies that improve existing research capacity, maximize the use of limited resources, and promote local-international partnership are crucial for sustaining research on climate and health.
登革热是一种受气候影响的传染病。基于气候的登革热预警可能是加强监测和控制的简单、低成本且有效的工具。基于当地气候和登革热的科学研究是推进基于气候的预警系统发展的基础。本研究旨在回顾气候与登革热相关的科学研究现状，以及在登革热流行国家建立基于气候的登革热预警系统的此类研究的前景或挑战，以马来西亚为例。
我们回顾了从统计建模、实验室测试和实地研究中得出的气候与登革热之间的关系。我们检索了电子数据库，包括 PubMed、Scopus、EBSCO（MEDLINE）、Web of Science 和世界卫生组织出版物，并评估了气候因素及其对登革热病例、蚊子和病毒的影响，以及气候与登革热领域的最新进展。
马来西亚的几项研究强调了气候与登革热之间的关系。温度、降雨量和湿度等气候因素与登革热有关；然而，这些关系并不一致。马来西亚的气候变化预测显示，未来登革热的风险将增加。从长远来看，关于气候和登革热的科学研究可以加强登革热监测。
马来西亚的各机构必须促进气候与虫媒传染病的研究，以推进基于气候的预警系统的发展。有效的策略对于维持气候与健康研究至关重要，这些策略包括提高现有研究能力、最大限度地利用有限资源以及促进本地-国际合作。
