The CDC publishes official numbers of COVID-19 cases in the United States.
In February 2020, at the beginning of the pandemic, a shortage of tests made it impossible to confirm all possible COVID-19 cases and resulting deaths, so the early numbers were likely undercounts. Another 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. From March 1, 2020 through the end of 2020, there were 522,368 excess deaths in the United States, which is 22.9% more than would have been expected in that time period. The CDC estimates that, between February 2020 and May 2021, only 1 in 1.3 COVID-19 deaths were attributed to COVID-19, and the true COVID-19 death toll was 767,000 as of May 2021.
The following numbers are based on CDC data, which is incomplete.
Confirmed coronavirus cases in the U.S. crossed 200,000 on Thursday, but experts agree the actual number of infected people is much higher. The lack of reliable data—a persistent problem since the pandemic began—has made it impossible to determine the actual size of the outbreak, hampering the U.S. response.
