COVID-19 and Excess All-Cause Mortality in the US and 18 Comparison Countries

COVID-19 and Excess All-Cause Mortality in the US and 18 Comparison Countries: The US has experienced more deaths from coronavirus disease 2019 (COVID-19) than any other country and has one of the highest cumulative per capita death rates. An unanswered question is to what extent high US mortality was driven by the early surge of cases prior to improvements in prevention and patient management vs a poor longer-term response. We compared US COVID-19 deaths and excess all-cause mortality in 2020 (vs 2015-2019) to that of 18 countries with diverse COVID-19 responses.
