From the Summary: "In the months since the COVID-19 [coronavirus disease 2019] outbreak was first diagnosed, it has spread to over 200 countries and all U.S. states. The pandemic has negatively affected global economic growth beyond anything experienced in nearly a century. Estimates so far indicate the virus could reduce global economic growth to an annualized rate of -4.5% to -6.0% in 2020, with a partial recovery of a rate of 2.5% to 5.2% in 2021. [...] The full economic impact of the pandemic likely will remain unclear until the negative health effects peak. This report provides an overview of the global economic costs to date and the response by governments and international institutions to address these effects."
