This document summarizes a presentation on research priorities for investigating the connections between COVID-19, the environment, and health. It introduces the HERA project, which aims to develop a European research agenda on these topics. The presentation outlines three main research goals: examining environmental drivers of SARS-CoV-2 emergence and spread; understanding the health impacts of COVID-19 in relation to environmental stressors like climate change and air pollution; and analyzing the integrated socioeconomic, political, and health implications of COVID-19 and different intervention strategies.
