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.
medical journal JAMA that examined excess mortality rates in the U.S. through December.
While that team similarly found the number of excess deaths far exceeded the official COVID-19 death toll, it disagreed that the gap could be blamed entirely on COVID-19 and not other causes.
"Their estimate of excess deaths is enormous and inconsistent with our research and others," said Dr. Steven Woolf, who led the Virginia Commonwealth team. "There are a lot of assumptions and educated guesses built into their model."
Other researchers applauded the UW study, calling the researchers' effort to produce a global model important, especially in identifying countries with small reported outbreaks but larger estimates of a true death toll, which could indicate the virus is spreading more widely than previously thought.
"We need to better understand the impact of COVID across the globe so that countries can understand the trajectory of the pandemic and figure out where to deploy additional resources, like testing supplies and vaccines to stop the spread," said Jennifer Nuzzo, an epidemiologist at Johns Hopkins.
Researchers at UW also released an updated forecast for the COVID-19 death count worldwide, estimating that roughly 2.5 million more people will die of COVID-19 between now and Sept. 1, driven in part by the dramatic surge of cases in India.
In the United States, researchers estimated roughly 44,000 more people will die of COVID-19 by September.
