Two years after the World Health Organization declared the coronavirus a global pandemic, new research suggests around 18.2 million people have died worldwide as a result. That toll is more than three times higher than the WHO's tally of nearly 6 million officially reported COVID-19 deaths through the end of 2021.
Some 1.13 million Americans have died due to the pandemic, the researchers estimate. By comparison, the current total of reported COVID-19 deaths in the U.S. stands at around 960,000
