Excess mortality caused by COVID-19, from March 1, 2020 to April 4, 2020.

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[1][2] and resulting deaths, so the early numbers were likely undercounts.[3][4][5][6] 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.[7] 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.[8] The CDC estimates that, between February 2020 and May 2021, only 1 in 1.3 COVID-19 deaths were attributed to COVID-19,[9] and the true COVID-19 death toll was 767,000 as of May 2021.[10]

The following numbers are based on CDC data, which is incomplete.

Measuring case and mortality rates

Deceased persons in a 53-foot "mobile morgue" outside a hospital in Hackensack, New Jersey on April 27, 2020

In early 2020, deaths from all causes exceeded the seasonal average,[11] and data from early 2020 suggest additional deaths that were not counted in official reported coronavirus mortality statistics.[12] Until February 28, 2020, CDC testing protocols allowed tests only for people who had traveled to China.[13] In most U.S. locations, testing for some time was performed only on symptomatic people with a history of travel to Wuhan or with close contact to such people.[14][15][16] The numbers were reported every Monday, Wednesday, and Friday and were split into categories: individual travelers, people who contracted the disease from other people within the U.S., and repatriated citizens who returned to the U.S. from crisis locations, such as Wuhan, where the disease originated, and the cruise ship Diamond Princess.[17]

By March 26, 2020, the United States, with the world's third-largest population, surpassed China and Italy as the country with the world's highest number of confirmed cases.[18] By April 25, the U.S. had more than 905,000 confirmed coronavirus cases and nearly 52,000 deaths, giving it a mortality rate around 5.7 percent. (In comparison, Spain's mortality rate was 10.2 percent and Italy's was 13.5 percent.)[19][20]

In April 2020, more than 10,000 American deaths had occurred in nursing homes. Most nursing homes did not have easy access to testing, making the actual number unknown.[21] President Trump established a Coronavirus Commission for Safety and Quality in Nursing Homes.[22][23] Subsequently, a number of states including Maryland[24] and New Jersey[25] reported their own estimates of deaths at nursing homes, ranging from twenty to fifty percent of the states' total deaths. A PNAS report in September 2020 confirmed that the virus is much more dangerous for the elderly than the young, noting that about 70% of all U.S. COVID-19 deaths had occurred to those over the age of 70.[26]

As of early August 2020, among the 45 countries that had over 50,000 cases, the U.S. had the eighth highest number of deaths per-capita. Its case fatality ratio, however, was significantly better where it ranked 24th in the world, with 3.3% of its cases resulting in death.[27] Several studies suggested that the number of infections was far higher than officially reported, and thus that the infection fatality rate was far lower than the case fatality rate.[28][29]

The CDC estimates that 40% of people infected never show symptoms (i.e. are asymptomatic),[30] although there is a 75% chance they can still spread the disease. And while children have a lower risk of becoming ill or dying, the CDC warns that they can still function as asymptomatic carriers and transmit the virus to adults.[30] The American Academy of Pediatrics's weekly report[31] from when states started reporting to September 17, 2020 tracked 587,948 child COVID-19 cases, 5,016 child hospitalizations, and 109 child deaths.[32]

Epidemiologists depend on accurate reporting of cases and deaths to advise government response,[33] and some have questioned the reliability of the numbers of confirmed cases.[34] Rates differ among U.S. states, and there are also racial and economic disparities.[35][36][37] After a group of epidemiologists requested revisions in how the CDC counts cases and deaths, the CDC in mid-April 2020 updated its guidance for counting COVID-19 cases and deaths to recommend that U.S. states report both confirmed and probable ones, though the decision is left to each state.[38]

On September 25, 2020, The Lancet published the largest study at the time to measure COVID-19 antibody levels in the US population, finding that less than ten percent of the U.S. population had been exposed.[39][40][41] The study was published at a time when, according to Newsweek, "some U.S. officials have floated the concept of herd immunity as a possible strategy to manage the national outbreak,"[42] and according to the lead author of the study, Stanford Center for Tubulointerstitial Kidney Disease director Shuchi Anand, "this study does not support that there is herd immunity."[43] The research also uncovered racial and economic disparities in populations with COVID-19 antibodies[44][35] and highlighted the need for public health intervention to address the disparities.[36][37] At the time of the publication of the study, Anand announced that researchers would monitor the study participants for months to help determine the effectiveness of COVID-19 mitigation tactics.[42][44][40]

On April 14, 2021, the Centers for Disease Control estimated that, as of March 2021, there had been 98.5–134.3 million infections in the United States.[45]

According to the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University as of 19:21 Eastern Standard Time (EST) on 7 August 2021, the total COVID-19 cases in the US has crossed the 35.73 million mark, with the death toll reaching 616 712.[46]

Death projections

On March 31, 2020, the CDC projected that eventually 100,000–240,000 Americans would die of coronavirus.[127] The lower end of the estimate was reached within two months after the CDC made its projection,[128] and the upper end was surpassed in November 2020.[129]

The CDC uses an ensemble forecast, meaning it receives predictions from multiple sources and aggregates them to make its own forecast. As of December 2020, the CDC included 37 modeling groups in its ensemble forecast and was predicting the death toll 4 weeks in advance.[130]

Examples:

  • At the end of May 2020, the CDC correctly projected the death toll would surpass 115,000 by June 20.[131][132]
  • At the end of July 2020, the CDC correctly projected the death toll would surpass 168,000 by August 22.[133]
  • In mid-October 2020, the CDC correctly projected the death toll would reach 230,000–250,000 by mid-November.[133]

In mid-February 2021, when the death toll had already reached 470,000,[134] the IHME projected that the death toll would reach 600,000 by June 1.[135] However, the death rate dropped during this time period and the total death toll on June 1 was not as high as expected, having reached only about 592,000.[136] The total of 600,000 was reached two weeks later.[137]
