More than 1,800 inmates housed at an Ohio correctional facility have coronavirus, a report said Sunday.

A total of 1,828 detainees at the Marion Correctional Institution in Marion, Ohio have tested positive for the illness, and 108 staff members have also been infected, according to the Ohio Department of Rehabilitation and Correction.

Of the sick inmates, 38 were being treated at an outside hospital. A total of 667 inmates were being quarantined at the facility. The jail houses about 2,500 inmates.

“Because we are testing everyone — including those who are not showing symptoms — we are getting positive test results on individuals who otherwise would have never been tested because they were asymptomatic,” the Ohio Department of Rehabilitation and Correction said in a statement.

“Also, our comprehensive testing approach of staff and inmates has assisted us in identifying asymptomatic individuals who have tested positive who can now be isolated from others in order to prevent further spread,” the statement read.

There have been 471 deaths in Ohio due to the coronavirus outbreak. More than 11,600 have tested positive for the illness in the state.
