Nine federal inmates at the Federal Correctional Institution in Danbury have tested positive for COVID-19, tied for the second most confirmed cases at a federal prison facility with Federal Medical Center Butner in North Carolina, according to data released Wednesday by the Bureau of Prisons. They lag behind only Federal Correctional Complex Oakdale in Louisiana, one of the hardest-hit states in the nation where cases have been rapidly increasing this week. Four staff members of the Danbury prison also have tested positive, according to the bureau.
