FORT WORTH, Texas More than 500 women at a federal medical prison in Texas have tested positive for the coronavirus, in one of the largest confirmed outbreaks at a federal prison, the Bureau of Prisons said. Only the federal prison in Seagoville, also located in the Dallas-Fort Worth area, had more infected inmates, with 1,156 cases as of Tuesday. Three weeks ago, the prison had reported only three confirmed cases of the virus among inmates. Since April, many inmates have told the Forth Worth Star-Telegram that they were concerned the virus could spread through the prison. Inmate Sandra Shoulders said mattresses used by women who have tested positive are piled up in a TV room.
