The HEat and HEalth African Transdisciplinary (HEAT) Center

The HEat and HEalth African Transdisciplinary (HE2AT) Center is a five-year project funded by the National Institutes of Health, Common Research Fund. It was launched in 2022 and consists of a data science and analytics platform that helps understand how extreme heat affects vulnerable groups in Africa.

The consortium includes trans-disciplinary researchers from South Africa, Côte d’Ivoire, Zimbabwe and the US, who range from climate scientists and data scientists to medical doctors and communication experts. The Center includes two sub-projects. In the first we collate data from around 200 longitudinal studies across Africa in an Individual Participant Data meta-analysis that documents the heat impacts on pregnancy outcomes. The second project investigates the Urban Heat Island effect in Johannesburg and Abidjan, Côte d’Ivoire, using data sources from satellites on the natural (e.g., vegetation) and the built environment, combined with weather, air pollution, and health outcome data.

We draw on health data from around 40 clinical trials and cohorts done by Research Units at Wits. Analyses inform design of an Early Warning System that uses a machine learning algorithm to predict an individual’s risk during extreme heat, taking into account forecasted weather, and characteristics such as age, geolocation and gender.
