Since March, The Marshall Project has been tracking how many people are being sickened and killed by COVID-19 in prisons and how widely it has spread across the country and within each state. Here, we will regularly update these figures counting the number of people infected and killed nationwide and in each prison system until the crisis abates.
This reporting was undertaken in partnership with The Associated Press.
By Aug. 25, at least 108,045 people in prison had tested positive for the illness, a 6 percent increase from the week before.
New cases among prisoners reached an all-time high in early August after slowing down in June. The growth in recent weeks was driven by big jumps in prisoners testing positive in Florida, California and the federal Bureau of Prisons as well as outbreaks in Arkansas, Hawaii and Oklahoma.
Cases first peaked in late April, when states such as Michigan, Ohio, Tennessee and Texas began mass testing of prisoners. Those initiatives suggested that coronavirus had been circulating among people without symptoms in much greater numbers than previously known.
There have been at least 108,045 cases of coronavirus reported among prisoners.
81,900 prisoners have recovered.

The first known COVID-19 death of a prisoner was in Georgia when Anthony Cheek died on March 26. Cheek, who was 49 years old, had been held in Lee State Prison near Albany, a hotspot for the disease. Since then, at least 927 other prisoners have died of coronavirus-related causes. By Aug. 25, the total number of deaths had risen by 4 percent in a week.
There have been at least 928 deaths from coronavirus reported among prisoners.

Given the huge differences in how many people are being tested in prisons for the virus, the effects of the pandemic have varied widely between different state prison systems. The first reported cases began popping up in Massachusetts and Georgia on March 20. In August, Hawaii, the last system whose prisoners had not gotten sick, reported its first confirmed cases of coronavirus. Here, you can choose to view the data for any state prison system and see how the numbers compare. For a summary of the number of cases in facilities run by the federal Bureau of Prisons, choose the “Federal” option.

While we know more about how prisoners are getting sick, another group of people is at risk in these facilities: correctional officers, nurses, chaplains, wardens and other workers. We know little about how coronavirus is affecting them, though they have the potential to carry it both into facilities and back out to their communities. It’s difficult to assess how prison workers are being affected because many aren’t being systematically tested.
In the most recent week, 18 states—Arkansas, Connecticut, Delaware, Florida, Idaho, Indiana, Kansas, Louisiana, Maryland, Mississippi, New Jersey, North Dakota, Pennsylvania, South Dakota, Tennessee, Texas, Vermont, West Virginia—released information on the number of their staff members tested for coronavirus. Where we do know about positive cases, most state corrections departments stress that the count includes only the employees who voluntarily report a diagnosis, often in the course of calling out sick.
While more than 24,055 prison staff members have tested positive, only 72 deaths have been publicly reported.
There have been at least 24,055 cases of coronavirus reported among prison staff.
17,026 staff have recovered.

We know very little about how many staff are tested, and in many states it’s not clear how many people are working in prisons right now. What we do know is that in several states prison employees began to get sick before the people they oversee. Using this tool, you can view the data for any state’s prison system and see how the numbers compare. For a summary of the number of cases in facilities administered by the federal Bureau of Prisons, choose the “Federal” option.

The Marshall Project will continue to track and publish data on coronavirus in our prison systems. If you have updates to the data to share or other comments, please contact us at info+covidtracker@themarshallproject.org.
We are publishing the raw data we have collected at data.world, in partnership with the Associated Press, and on Github. You can download the data to examine for yourself or to use in your research. If you do use our data, please let us know.
Since March 26, reporters from The Marshall Project and the Associated Press have been collecting data on COVID-19 tests administered to people incarcerated in all state and federal prisons, as well as the staff in those facilities. We request this data every week from state departments of corrections and the federal Bureau of Prisons; however, not all departments provide data for the date requested. These numbers have been grouped by the week the data was collected.
For six states with unified prison and jail systems—Alaska, Connecticut, Delaware, Hawaii, Rhode Island, Vermont—we count testing and case numbers from both detainees awaiting trial and sentenced prisoners. Similarly, in Maryland, several pre-trial facilities in Baltimore City are included in the figures.
To estimate the rate of infection among prisoners, we collected population data for each prison system before the pandemic, roughly in mid-March, and in April and June. Beginning the week of July 28, we updated all prisoner population numbers, reflecting the number of incarcerated adults in state or federal prisons. Prior to that, population figures may have included additional populations, such as prisoners housed in other facilities, which were not captured in our COVID-19 data. In states with unified prison and jail systems, we include both detainees awaiting trial and sentenced prisoners.
We calculate the rates of infection and death per 10,000 prisoners to allow for the easiest comparison with most prison systems. In early versions of this project, we had used a rate of 100,000 prisoners. An earlier version of the May 27 tables counting positives and deaths mislabeled the rate column with the wrong denominator and has been corrected.
The overall U.S. rate of infection was calculated using case counts from The COVID Tracking Project and population data from the U.S. Census Bureau.
To estimate the rate of infection among prison employees, we collected staffing numbers for each system before the pandemic, roughly in mid-March, and in mid-April. Where current data was not publicly available, we acquired other numbers through our reporting, including calling agencies or from state budget documents. In six states, we were unable to find recent staffing figures and thus did not calculate rates: Alaska, Hawaii, Kentucky, Maryland, Montana, Utah.
As with all COVID-19 data, our understanding of the spread and impact of the virus is limited by the availability of testing. Epidemiology and public health experts say that aside from a few states that have recently begun aggressively testing in prisons, it is likely that there are more cases of COVID-19 circulating undetected in facilities. Sixteen prison systems, including the Federal Bureau of Prisons, would not release information about how many prisoners they are testing.
Corrections departments in Indiana, Kansas, Montana, North Dakota and Wisconsin report coronavirus testing and case data for juvenile facilities; West Virginia reports figures for juvenile facilities and jails. For consistency of comparison with other state prison systems, we removed those facilities from our data that had been included prior to July 28. For these states we have also removed staff data, except in West Virginia, where staff for juveniles centers and jails cannot be disaggregated from the totals. Similarly, Pennsylvania’s coronavirus data includes testing and cases for those who have been released on parole. We removed these tests and cases for prisoners from the data prior to July 28. The staff cases remain.
Early weeks of data for Vermont included multiple tests of the same prisoner. Starting on May 13, the data now accurately reflect the number of individual prisoners tested in Vermont.
In Texas, updates to the data overcounted the number of employee tests for the weeks of May 13, May 20 and May 27 after the state redesigned its website and how it classified tests for employees. These figures have been amended.
Beginning the week of June 2, we moved our data collection up by one day. Data for that week represents a six-day count of cases between May 28 and June 2.
For the week of July 14, Michigan undertook an audit of cases and found duplicates that needed to be removed from its unique numbers. As a result, the number of cases dropped by 5 percent from the previous week. To estimate case counts for previous weeks, we have adjusted the original figures by that percentage. As an additional result of the audit, the prisoner test numbers fell by 717.
Starting with the week of July 21, South Carolina’s Department of Corrections began to report cases—but not testing counts—for prisoners held in “other locations,” such as county jails and hospitals.
The number of staff deaths in Maine for the week of July 21 was wrong. It should have been 0 and has been corrected.
In the week of Aug. 4, the Federal Bureau of Prisons began to report four deaths of people who had been released to home confinement, under the supervision of halfway houses. Their testing and case totals, however, do not include people on home confinement, and testing figures do not include private prisons.
In mid-August, Pennsylvania began reporting cases for prisoners and staff in community correction facilities. We have included these cases starting with numbers as of Aug. 18, and have updated inmate population figures to add individuals held in community corrections facilities. The number of individuals recovered among both staff and prisoners don't count individuals in community corrections facilities.
The total number of prisoner cases we reported dropped between Aug. 27 and Aug. 28, when we incorporated a data update from New Jersey that removed about 4 percent of cases in earlier weeks. New Jersey updated its prisoner case totals to remove cases where a prisoner tested negative for COVID-19 after initially testing positive. To estimate case counts for previous weeks, we have adjusted the original figures by that percentage.
