A doctor arrives to carry out tests for tropical diseases: Evelyn scoffs at him from her bed in the infirmary. Dr Granger warns Erica that if Sally was the contact there could be an epidemic. No-one can explain how Lizzie became infected until Jim remembers that she'd brought Sally a meal when she was in sickbay. Georgie is forcibly removed from solitary for an examination and an injection of antibiotics. Dr Granger suspects typhoid and orders all food in the kitchen to be destroyed and that block H should be isolated from the rest of the prison. He also tells the officers they won't be allowed to go home. Judy reports back to Bea that she wasn't allowed to get out of the block to go to the library. Evelyn challenges the nurse, claiming that she could cure herself and refusing the injection. Sandra is moved out of isolation to make room for the female officers: when she finds out about the quarantine she begs Vera not to put her back with the other women. Georgie is put in Judy's cell.
