Inmates do a deep cleaning in a cell pod to prevent the spread of COVID-19 at the San Diego County Jail in April 2020. A new study says crowded jails may have contributed to millions of COVID-19 cases across the United States.

If the U.S. had done more to reduce its incarceration rate, it could have prevented millions of COVID-19 cases.

That's the conclusion of researchers who conducted what they say is the first study to link mass incarceration rates to pandemic vulnerability. Many of those preventable cases, they add, occurred in communities of color.

The U.S. jail and prison system acts as an epidemic engine, according to the study from researchers at Northwestern University and the World Bank.

That engine is driven by a massive number of people who, despite some counties' efforts to trim jail populations, have been cycling between cramped detention facilities and their home communities.

After analyzing data from 1,605 counties, the researchers linked an 80% reduction in the U.S. jail population to a 2% drop in the growth rate of daily COVID-19 cases.

Such a substantial drop in the incarceration level could have been achieved by instituting alternatives to jail for nonviolent offenses, according to the researchers Dr. Eric Reinhart of the Northwestern University Feinberg School of Medicine and Daniel Chen of the Toulouse School of Economics and the World Bank.

That 2% reduction is a conservative estimate, but it still represents a dramatic potential shift, Reinhart told NPR.

When compounded daily, Reinhart said in a Northwestern news release about the study, "even just a 2% reduction in daily case growth rates in the U.S. from the beginning of the pandemic until now would translate to the prevention of millions of cases."

Tens of thousands of deaths could also have been prevented, he said.

The U.S. has long had the world's highest incarceration rate among industrialized countries reporting such statistics. During the pandemic, it has also reported more COVID-19 cases and deaths than any other country despite having less than 5% of the global population.

The new research, published Thursday in the journal JAMA Network Open, suggests those circumstances are directly related.

On average, U.S jails currently host some 650,000 detainees every day, according to Reinhart. The dynamic also includes more than 220,000 full-time jail staff, who commute back and forth from their homes each day, the study said.

Many of those detainees are held in custody for only short periods of time as they either await trial or serve short sentences. The U.S. jail population has a 55% weekly turnover rate, according to the study.

"This jail churn effectively produces epidemic machines that seed outbreaks both in and beyond jails, undermining public safety for the entire country," Reinhart said.

Citing crowded conditions and poor health care in jails and prisons, a summary of the study from Northwestern said the U.S. facilities "have effectively become infectious disease incubators," putting the country at a higher epidemiological risk.

The link between prisons and public health is one of the reasons Black and Hispanic communities have been disproportionately harmed by the coronavirus, the study's authors said.

The spread of the coronavirus between jails and communities "likely accounts for a substantial proportion of the racial disparities we have seen in COVID-19 cases across the U.S.," Reinhart said.

"Ultimately, this also harms all U.S. residents regardless of race, class or partisan affiliations, as disregarding the health of marginalized people inevitably causes harm albeit unevenly to everyone else in a society, too," he added.

The benefits of cutting the jail population would be magnified, Reinhart and Chen wrote, in counties with high proportions of Black residents as well as in urban areas with above-average population density.

The study's findings are based on data from jails that reduced their populations at rates from 20% to 50% during the pandemic in response to health risks from COVID-19.

The researchers sought to predict what the results would look like if the U.S. dropped its jail population by 80%, which would bring the country closer to the average rates seen in peer nations.

The study relied on data gathered at the county level from January 2020 to November, representing 72% of the U.S. population.
