The staff member at the Rochester Federal Medical Center who tested positive for COVID-19 has not been inside the prison since July 7, according to a Federal Bureau of Prisons spokesman.

The staff member left the state and tested positive upon their return, the spokesman wrote in an email.

"Additional isolation and quarantine of staff and inmates is unnecessary as the staff member is not at the institution," the spokesman wrote.

The positive test was posted Friday, July 31, as part of the previous day's update. This is the second time an FMC staff member has tested positive for the coronavirus. In both instances, the staff member had not been in the facility in the weeks before their positive test result.

According to BOP data, 122 inmates have been tested at FMC Rochester. Of that number, results for 24 of the tests are still pending.
