There are few if any, issues that have taken over the entire planet and affected so many aspects of life on Earth as climate change. Its effects are widespread and mind-blowing, impacting everything from the weather to biodiversity. But one of the areas with the most far-reaching effects is public health: changes in where certain diseases appear, how often and how hard they hit us, all have their roots at least partly in the climate change crisis. The recently held Kigali Summit on ‘Disease in the Climate of Change’ brought together scientists, policymakers, and patients for an open dialogue on how our warming planet changes disease, and how to predict and protect against the consequences. This article provides an overview of the discussions, identifying key elements where climate change and disease interplay, and the environmental starting pieces.
The Intersection of Climate Change and Disease
Climate change affects disease dynamics through various mechanisms, including:
- Temperature changes: As temperatures rise, many pathogens and their vectors – such as mosquitoes – can spread to new locations.
- Patterns of Precipitation: Changes in rainfall create breeding grounds for vectors of disease and lead to outbreaks of waterborne illnesses.
- Increased frequency of extreme weather events such as floods and droughts – especially when sanitation infrastructure is disrupted – can enhance conditions for disease outbreaks.

The Kigali Summit confronted the complicated nature of linking infectious diseases and climate change using a wide-ranging panel of experts. The summit included emerging priorities and actions, among which were:
1. Climate-Driven Shifts in Disease Patterns
Migrations of infectious diseases due to climate change was one of the major items on the summit agenda: Climate change is likely to fundamentally shift the pattern of diseases. Among the points in this regard are:
- Tackling vector-borne diseases Like the other topics discussed here, shifts in temperature and precipitation are altering vector habitats, such as the range and habitat of mosquitoes, ticks, and flies. Malaria and dengue fever once limited to tropical regions are now appearing at higher altitudes and in formerly cooler areas. The summit explored ways that increased surveillance and adaptation could help.
- Waterborne diseases: more intense and frequent rains and flooding lead to contamination of water sources, increasing the risk of cholera, typhoid fever, and other diseases. The summit highlighted the need to strengthen water, sanitation, and hygiene (WASH) infrastructure.
- Zoonotic Diseases: In addition to malaria, climate change can also influence the spread of ‘zoonotic diseases’, where the transmission jumps from animals to humans. Migratory animals shifting habitats through changing climates can be a source of new pathogens, like Ebola and Hantavirus.
2. Vulnerability of Communities
The summit underscored that the worldview of climate change on disease is not uniform, its burden falling more heavily on vulnerable communities. Discussion points included:
- Health Inequities: Low-income and marginalized communities have limited access to health care and are most vulnerable to climate change. At the summit, groups advocated for ‘equity-focused programming’ aimed at protecting the most vulnerable while enhancing equitable access to health tools.
- Community Adaptation Measures: Communities will face a changed disease environment. To reduce their risk of disease, it is important to develop early warning systems for diseases and establish better mechanisms of vector control. Local health infrastructure also needs to be scaled up.
3. Integrating Climate and Health Policies
Effective interventions to climate-related health problems need coordinated policy solutions that combine responses to climate change and public health. Among the actions proposed were:
- Coordinating policy: The summit called for health and climate agencies to better coordinate their policies at both the national and international levels. Coordinated policies can help avoid duplicated efforts and ensure that climate change is taken into account in the planning of health efforts, and vice-versa.
- Investment and Support: Strong and effective climate-resilient health systems require adequate finances. The summit outlined increased investments in research, infrastructure and capacity needs to support health and climate activities.
- Data and research: The summit focused on improved data collection and research as the key to understanding the link between climate change and disease. Strong data is essential to provide a basis for policy decisions and intervention strategies.
4. Community-Based Approaches
Community engagement is key to mitigating the effects of climate change on health. The summit featured a series of community-driven strategies:
- Education and Awareness: It is possible to raise awareness among the population and communities that are most at risk of the health consequences of climate change. This will empower them to take steps that might prevent the spread of such consequences before they happen. For example, it is quite possible to educate communities and people on the best ways to avoid the spread of vector-borne and waterborne diseases.
- Local Solutions: Local communities may be best placed to find local solutions to climate-related health challenges. The summit described and supported some successes of community-based initiatives, and encouraged their scaled-up replication.
- Engaging Local Leaders: massive mobilization for community action and advocating for health and climate policies needs local leaders The summit focused on the important role that local leaders can have in mobilizing community action and advocating for policies that promote health and climate.
Innovations and Best Practices Discussed
In addition, the Kigali Summit demonstrated novel and best practices in tackling climate change and health:
1. Climate-Resilient Health Systems
- Figure 1: Integrating climate risk assessments with health planning and infrastructure design can lead to building climate-resilient health systems
- Strengthening Health Infrastructure: By ensuring that health facilities are protected from the impacts of extreme weather events and are equipped to address climate-related health issues.
- Investing in Early Warning Systems: Setting up systems to detect, and respond to, the impacts of disease outbreaks owing to changes in climate (such as increased rainfall or temperature spikes).
2. Nature-Based Solutions
Nature-based solutions involve leveraging natural processes to address climate and health challenges. Examples include:
- Rehydrating Wetlands: Restoring wetlands is an important adaptation strategy for dealing with floods and reducing breeding habitats for vectors of disease.
- Urban Green Spaces: Vegetation interventions within or around urban areas can increase evapotranspiration, improve air quality, and reduce temperatures to reduce heat islands in the built environment, which can help modify vector populations and public health.
3. Technological Innovations
Technological advancements are playing a role in improving disease monitoring and response. Examples include:
- Remote Sensing: Using satellite data to monitor environmental changes and predict disease outbreaks.
- Mobile Health Applications: Deploying mobile apps for real-time disease surveillance and health education.
Success Stories and Case Studies
The summit that’s in the headlines emphasizes some bright spots where new and emerging innovations are making a significant dent in climate-related health threats:
1. Malaria Control in Ethiopia
An intervention in Ethiopia integrated vector control, climate modeling, and community engagement to reduce malaria. The use of climate data for malaria forecasting and intervention targeting improved the program’s reach and impact.
2. Cholera Prevention in Bangladesh
These include the vast floods of Bangladesh, where a robust early warning system and community-based interventions have reduced flooding-related cholera outbreaks from near-epidemic proportions to manageable spikes. Early warning systems and modernized wastewater infrastructure have helped to mitigate the risk of rising sea levels.
3. Heat Health Interventions in Europe
For example, many European cities have developed ‘heat health action plans’ to protect vulnerable populations in the event of a heatwave, including interventions such as cooling centers, public information, and health alerts that show examples of effective adaptation responses to the high-temperature extreme.
The Path Forward
To make headway on this front, five major steps are needed: 1) Streamline and coordinate actions to mitigate climate change and enhance health.
1. Strengthening Policy Frameworks
Integrated policy development and delivery, to combat climate change and prioritizing health, is crucial. Climate-resilient health systems need to be at the forefront of policies, and climate consciousness needs to be incorporated into all health planning.
2. Investing in Research and Innovation
The intricate link between climate change and disease requires further study and innovation to discover solutions. Being willing to invest in new technologies, data, and research will help us overcome these challenges.
3. Promoting International Collaboration
When it comes to global challenges, global solutions are often the answer. International cooperation in sharing knowledge and expertise, resources, and in scaling up best practices is critical if we are to improve global health in the face of climate-related impacts.
4. Empowering Communities
Encouraging individual communities to become active in addressing these events and minimizing the health impacts of climate change is crucial. About 11,068 deaths of Americans under age 65 in 2006 were attributed to air pollution. We can achieve better and more effective public health and community health by supporting community-based approaches, creating local solutions, and improving access to educational resources aimed at strengthening resilience.
The Kigali Summit on climate change and disease also provided some important insights, demonstrating the urgent need for cohesive strategies, and reinforcing the imperative to integrate disease research into the broader context of addressing climate change impacts on human health.
Their frank exchanges and recommendations highlight the need for committed collaboration, sustained research, and community engagement to manage the climate health challenges that are still to come. The Kigali Summit has connected climate and health in the minds of thousands of people and will continue to do so as the world grapples with what the future has in store for both.
