More than 150,000 Uncounted COVID-19 Deaths Occurred Early in the Pandemic, a Study Finds
Researchers used machine learning to uncover 150,000 unrecognized COVID deaths, mostly among marginalized groups, raising the 2020–2021 death toll to nearly one million in the U.S.
- On Wednesday, researchers published a study in Science Advances estimating between 150,000 and 160,000 unrecognized COVID-19 deaths on top of 840,251 officially reported fatalities in 2020 and 2021.
- Marginalized communities in Alabama, Oklahoma, and South Carolina experienced the highest undercounting rates, as testing barriers and fragmented death investigation systems prevented accurate diagnosis outside hospitals.
- Using machine learning to analyze death certificates, researchers estimated that for every five recognized COVID-19 deaths, one additional death went unmarked due to low testing availability early in the pandemic.
- Dr. Nahid Bhadelia, founding director of the Boston University Center for Emerging Infectious Diseases Policy and Research, said "This work is important because our ability to detect and correctly assign deaths" shapes pandemic response.
- Katherine Hempstead, senior policy adviser at the Robert Wood Johnson Foundation, called for standardizing death investigation, noting geographic variations reduced accuracy of national surveillance data and pandemic response.

The initial number of deaths from the COVID-19 pandemic was much higher than the official U.S. count, according to a new study highlighting the dramatic disparities in unaccounted deaths. In 2020 and 2021, around 840,000 deaths from COVID-19 were recorded on death certificates. However, a group of researchers, using artificial intelligence, estimates that there were probably up to 155,000 additional deaths not recorded outside hospitals during t…
As many as 1 in 5 COVID-19 deaths went uncounted during the pandemic's first 2 years, study finds
As many as 1 in 5 COVID-19 deaths went uncounted during the first two years of the pandemic, a new study found. Most that were missed were among minorities and vulnerable groups, researches said.
