More than 200,000 people in the United States have now died from COVID-19. But the death toll of the U.S. epidemic is likely much higher, according to a new, first-of-its-kind study from researchers at the University of Pennsylvania, Boston University, and the Robert Wood Johnson Foundation. Available as a pre-print on medRxiv ahead of peer-reviewed publication, the study estimates the number of ‘excess deaths,’ those that occurred from February through September 2020 above what would be expected in a normal year.
