 This study developed an open-source and customizable tool to predict the impact of the expansion of COVID-19 on the level of preparedness of the health systems of different Latin American and Caribbean countries. The tool uses a deterministic epidemiological model to provide valuable information on the dynamics of transmission and how it could impact on health systems. It also allows policymakers to adjust the model's parameters according to the specific pandemic trajectory and policy context.
