State prisons are isolating prisoners in their cells to limit opportunities for coronavirus to spread.
The Oklahoma Department of Corrections says the new measure, normally reserved to prevent prison violence, is aggressive but necessary. The prison agency says its staff will bring prisoners their food, medicine and other necessities to prevent groups of prisoners from gathering.
Last week, the agency discovered one of its prison staff members tested positive for COVID-19. An agency spokesperson wouldn't say when the employee last had contact with prisoners and other employees.
