Louisiana’s prison system this week began “mass testing” at a second state correctional facility.

The results show two-thirds of inmates who contracted COVID-19 between two prison facilities the agency considers “hot spots” tested positive without showing symptoms.

At the all-female prison facilities in St. Gabriel and Jetson, a total of 317 inmates tested positive, including 210 who were asymptomatic. The Louisiana Department of Public Safety and Corrections started testing all inmates at the facility where women are housed at Elayn Hunt Correctional Center weeks ago, after noticing it was a hot spot.

Two coronavirus-related inmate deaths stemmed from women’s facility in St. Gabriel.
