PROVIDENCE, R.I. (AP) — Dozens of detainees and several staff members at a Rhode Island jail have tested positive for COVID-19 this week, according to the facility’s warden.

Fifty detainees and seven staff members at the publicly-owned but privately-run Wyatt Detention Facility in Central Falls have tested positive, Warden Daniel Martin said in a statement Thursday.

The outbreak started when one detainee tested positive last week.

In response, the facility has stepped up testing.

“We have been in contact with the RI Department of Health on our existing COVID protocols which include testing and quarantining every incoming detainee for 14 days, mandatory mask usage for staff and detainees, and thorough sanitization of common areas/surfaces,” Martin wrote.

“We have added additional protocols based on RI DOH guidance which include ongoing, mandatory testing of detainees and staff, and not allowing detainees from different pods to come into contact with each other,” he said.

The facility houses many people being detained by federal immigration authorities.
