on Climate and Health for Africa | 22-25 May 2023

About the meeting

The Program Committee of the Chapman on Climate and Health in Africa has been working to create the most inclusive meeting that brings together scientists and policy makers from across Africa and North America.

Due to health and safety concerns, restrictions on international travel and visa restrictions for entry into the United States, we have made the decision to move the dates of the onsite conference in Washington, DC to 22-25 May 2023.  We hope that this change will enable researchers from around the world to participate in person in this important conference.

The Program Committee continues its work on the conference and will provide updates, including opportunities for the community to get together online in advance of the meeting, as information becomes available. New abstract submission deadlines and other timing will also be announced in the near future.

We look forward to coming together to connect as a community in May 2023.

It has been well established that extremes in the climate system have significant impact on human health, including infectious diseases and heat related illnesses. This conference aims to bring together climate scientists, health scientists and professionals, policy makers, and program managers to address the current status and future potential of climate-informed forecasts. Participants will discuss the extent to which the climate and health community can work together to advance health early warning systems.

Meeting goals

The overarching goal of the conference is to take advantage of advances in weather and climate forecasting and in climate-informed disease modeling, early warning, and predictions to enable decision support services in human health. The objectives are: (1) to review the state of the knowledge of the influence of climate on infectious diseases and non-communicable diseases, especially heat related illnesses; (2) to stimulate discussion between researchers, practitioners, and policy makers to advance climate-based health early warning; (3) to work collaboratively with program managers and decision makers on identifying best approaches to enable the use of climate information to reduce disease risk and benefit the public health.

Global Climate-Based Chikungunya Risk Mapping

Global Climate-Based Chikungunya Risk Mapping and Early Actions

Description: Chikungunya is a viral disease transmitted to humans by infected mosquitoes. Symptoms vary and can include fever, muscle or joint pain, and rash. Death from chikungunya is rare. The global chikungunya monitoring and forecasting (CHIKRisk) provides a platform for mapping occurrences of Chikungunya worldwide. This 60-minute-long panel will discuss Chikungunya vectors and ecology, global surveillance of chikungunya outbreaks, modeling framework and forecasting of chikungunya risk, dissemination, application, and preventive measures. Each panelist will give a brief 5-minute introductory remark and presentations will be followed by a Q&A session.

Chapman Conference Format Overview

Each theme will feature two oral sessions, a poster session, and a panel. Posters are strongly encouraged to foster discussions that lead to recommendations towards advancing health early warning systems. The panel and selected oral presentations will feature invited speakers. Contributed abstracts are welcomed for the poster sessions on all three themes. A small number of submitted abstracts will be selected for oral presentations, in consultation with the contributing authors.

    How Climate Impacts HealthOur current understanding of how climate affects health is presented in this session to provide a foundation for the subsequent sessions discussing actionable climate-informed forecasts. All aspects of the climate-health connection are covered, including both disease and stressors such as heat and humidity.

    Actionable climate-informed forecasts of infectious disease: achievements and needsIncorporating climate drivers explicitly in infectious disease models provides an important avenue for forecasting incidence and disease risk from sub-seasonal to seasonal to interannual time scales. This is the case for vector-borne, water-borne, and some directly transmitted airborne infections. Presentations will address the current achievements and challenges of producing such climate-informed forecasts for the African continent, for different classes of infectious diseases and at different temporal and spatial scales. Different modeling approaches and their advantages/disadvantages will be considered, from statistical to process-based, to forecasting ensembles. Climate information can be included in disease models based on observations or forecasts.

    Actionable climate-informed forecasts of heat related illnesses: achievements and needsExtreme heat in Africa remains a significant threat to human health. Greater action is required to support preparedness and adaptation in order to mitigate its impacts across communities as well as health systems. This session aims to provide a constructive and informative dialogue to highlight scientific achievements and discuss the continued need to shape and inform scientific efforts, which support and improve the health sector services with regards to extreme heat.
