People in prisons and jails are disproportionately likely to have chronic health problems including diabetes, high blood pressure, and HIV, as well as substance use and mental health problems. Nevertheless, correctional healthcare is low-quality and difficult to access. It's also expensive: Astonishingly, most prisons charge incarcerated people a co-pay for doctor visits.
The downstream effects — for both incarcerated people and the general public — have been disastrous: Mass incarceration has shortened the overall U.S. life expectancy by 5 years.
Below is our key research into the public health effects of incarceration:
Reports and campaigns
Our report shows that over half a million cases of COVID-19 in the summer of 2020 — or 13% of all cases — were attributable to the passage of the virus into, through, and out of crowded prisons and jails.
We worked with the ACLU to evaluate — and score — all 50 states’ criminal justice responses to the pandemic. Most states have ignored both the obvious risks to incarcerated people and the warnings of public health experts.
In addition to our two major reports on COVID-19 in prisons and jails, we've published a list of policy recommendations, an explainer on social distancing behind bars, a powerful fact sheet, and much more. We're also tracking where pandemic-related policy changes are taking place.
At least 4.9 million people go to county and city jails each year, our national analysis shows. We find that people who go to jail - particularly those who go more than once a year - are more likely to have preexisting health problems.

Originally published in the April 2000 issue of Mass Dissent.
One of the worst criminal justice policy failures — responding to drug use with punishment rather than care — also puts public health at risk.
Tens of millions of people are dealing with the "collateral consequences" of punishment: effects such as homelessness that last long after someone has served their sentence. These harms also impact public health.
Visits and phone calls mitigate the harmful effects of prolonged isolation behind bars. But jails and prisons make staying in touch difficult, particularly for poor families.
