The CDC publishes official numbers of COVID-19 cases in the United States.
The CDC estimates that, between February 2020 and September 2021, only 1 in 1.3 COVID-19 deaths were attributed to COVID-19. The true COVID-19 death toll in the United States would therefore be higher than official reports, as modeled by a paper published in The Lancet Regional Health – Americas. One way to estimate COVID-19 deaths that includes unconfirmed cases is to use the excess mortality, which is the overall number of deaths that exceed what would normally be expected.
