From the Summary: "The COVID-19 [coronavirus disease 2019] viral pandemic is an unprecedented global phenomenon that is also a highly personal experience with wide-ranging effects. On September 20, 2021, U.S. viral deaths surpassed the 675,446 total from the 1918 Spanish flu, the previous worst U.S. pandemic-related death total on record. The pandemic has disrupted lives across all countries and communities and negatively affected global economic growth in 2020 beyond anything experienced in nearly a century. Estimates indicate the virus reduced global economic growth in 2020 to an annualized rate of around -3.2%,with a recovery of 6.0% projected for 2021. Global trade is estimated to have fallen by 5.3% in 2020, but is projected to grow by 8.0% in 2021. According to a consensus of forecasts, the economic downturn in 2020 was not as negative as initially estimated, due in part to the fiscal and monetary policies governments adopted in 2020. In most countries, economic growth fell sharply in the second quarter of 2020, rebounded quickly in the third quarter, and has been mostly positive since. Although lessening, the total global economic effects continue to mount. [...] This report provides an overview of the global economic costs to date and the response by governments and international institutions to address these effects."
