Project Summary / Abstract Dengue, a potentially life-threatening disease, has increased 30-fold in the last 50 years. In Indonesia, 1 in 3 children have had a dengue infection by 5 years old. Islands in the Indo-Pacific are highly vulnerable to climate change and water insecurity, two key drivers of arbovirus spread. Predicting and mitigating arbovirus transmission in the Indo-Pacific is critical to addressing the increasing risk of arboviruses in the U.S. In the next several decades, half the U.S. may have habitat suitable for Aedes aegypti and Ae. albopictus, mosquitos which spread dengue, chikungunya, Zika, and yellow fever viruses. Revitalizing Informal Settlements and their Environments (RISE) is a cluster randomized control trial evaluating the benefits of upgrading local water infrastructure in urban slums in Indonesia and Fiji. The RISE intervention is a prototype for future slum upgrading to address climate change and water insecurity throughout the Indo- Pacific. Although the World Health Organization recommends permanent environmental modification as an arbovirus control strategy, this has never before been rigorously tested. RISE provides an important opportunity to evaluate whether this model decreases or inadvertently increases arbovirus transmission. In addition to evaluating a new paradigm for mitigating arbovirus transmission, RISE is an ideal platform to assess gaps in knowledge about environmental drivers of arbovirus transmission. My hypothesis is that modifiable environmental conditions drive arbovirus transmission in these communities. To test this hypothesis, I will leverage the RISE platform to study arbovirus risk factors in this region and evaluate the impact of permanent environmental modification on arbovirus transmission in urban slums. I will also create a mathematical model to simulate arbovirus transmission in this region under a range of climate change and intervention scenarios. I have developed a customized career development plan that aligns with my proposed research. It incorporates both formal and informal training under the mentorship of Drs. LaBeaud and Luby. This training plan draws upon my existing expertise in global health, tropical medicine, and epidemiology; it will enhance my expertise in laboratory diagnostics, geospatial analysis, and mathematical modeling. The planned didactics and technical training included here will provide the foundation necessary to achieve my goal of becoming an academic physician focused on mitigating the spread of infectious diseases in the era of climate change.

项目总结/摘要 登革热是一种可能危及生命的疾病，在过去50年中增加了30倍。在印度尼西亚，三分之一 儿童在5岁时感染登革热。印度-太平洋岛屿极易受气候影响 气候变化和水不安全是虫媒病毒传播的两个关键驱动因素。预测和减轻虫媒病毒 在印度-太平洋地区的传播对于解决美国日益增加的虫媒病毒风险至关重要。 几十年来，一半的美国可能有适合埃及伊蚊和Ae的栖息地。白纹伊蚊 传播登革热、基孔肯雅热、寨卡和黄热病病毒。 振兴非正式住区及其环境（RISE）是一项随机对照试验， 印度尼西亚和斐济城市贫民窟当地水基础设施升级的好处。RISE干预 是未来贫民窟改造的原型，以解决整个印度的气候变化和水不安全问题， 太平洋是如此虽然世界卫生组织建议将永久性环境改造作为一种 虫媒病毒控制策略，这是以前从未经过严格测试。RISE提供了重要的 有机会评估该模型是否会减少或无意中增加虫媒病毒的传播。 除了评估减轻虫媒病毒传播的新模式外，RISE还是一个理想的平台， 评估在虫媒病毒传播的环境驱动因素方面的知识差距。我的假设是 可改变的环境条件促使虫媒病毒在这些社区传播。为了验证这个假设， 我将利用RISE平台研究该地区的虫媒病毒风险因素，并评估 对城市贫民窟虫媒病毒传播的永久性环境改造。我还将创建一个 数学模型，以模拟在一系列气候变化下该地区虫媒病毒传播， 干预情景。 我已经制定了一个定制的职业发展计划，与我提出的研究相一致。而纳入 在LaBeaud博士和吕比博士的指导下进行正式和非正式的培训。该培训计划吸引了 在我现有的全球卫生、热带医学和流行病学方面的专业知识基础上， 实验室诊断、地理空间分析和数学建模。计划的教学和技术 这里所包含的培训将为我实现成为一名学者的目标提供必要的基础 在气候变化的时代，医生专注于减轻传染病的传播。
