A new study estimates that the number of people who have died of COVID-19 in the U.S. is more than 900,000, a number 57% higher than official figures.
Worldwide, the study's authors say, the COVID-19 death count is nearing 7 million, more than double the reported number of 3.24 million.
The analysis comes from researchers at the University of Washington's Institute for Health Metrics and Evaluation, who looked at excess mortality from March 2020 through May 3, 2021, compared it with what would be expected in a typical nonpandemic year, then adjusted those figures to account for a handful of other pandemic-related factors.
The final count only estimates deaths "caused directly by the SARS-CoV-2 virus," according to the study's authors. SARS-CoV-2 is the virus that causes COVID-19.
Researchers estimated dramatic undercounts in countries such as India, Mexico and Russia, where they said the official death counts are some 400,000 too low in each country. In some countries — including Japan, Egypt and several Central Asian nations — the Institute for Health Metrics and Evaluation's death toll estimate is more than 10 times higher than reported totals.
