PITTSBURGH (WPXI) — A second employee at Rivers Casino has tested positive for COVID-19. Officials said the employee last worked on June 13, but they didn’t specify where at the casino they work. Rivers has had heavy guidelines to limit the amount of exposure to the virus, as most of southwestern Pa. moved into the green phase. Casino officials said all employees and guests that were in close proximity to that employee will be notified by the Allegheny County Health Department. Rivers also will begin temperature checks for guests in addition to employees. Anyone with a temperature above 100.4 degrees will not be allowed to access the gaming floor.
