ABSTRACT

Studies on the transmission of coronavirus disease 2019 (COVID-19) indicate that geo-environmental factors played an important role in the global pandemic. However, there has been no systematic review of the impact of geo-environmental factors on the global transmission of COVID-19 in the geographic context. As such, we reviewed 49 well-chosen studies to reveal the impact of geo-environmental factors (including the natural environment and human activity) on the global transmission of COVID-19, and to inform strategies for intervention that could mitigate the global effects of the pandemic. . Existing studies frequently mention the impact of climatic factors (eg temperature and humidity); in contrast, a more decisive influence can be achieved through human activity, including human mobility, health factors and non-pharmaceutical interventions (NPIs). The results above exhibit distinct spatio-temporal heterogeneity. The related analytical methodology consists of sensitivity analysis, mathematical modeling and risk analysis. For future studies, we recommend highlighting geo-environmental interactions, developing geographic statistical models for multiple waves of the pandemic, and investigating NPIs and patterns of care. We also offer four implications for the practice of addressing the global transmission of COVID-19.
