As COVID-19 cases slowly started to tick up at Kettle Moraine Correctional Institution in early September, inmate Shun Warren was trying his best to stay healthy. He wore a mask, kept 6 feet away from his fellow inmates, tried not to touch his face and washed his hands as often as possible, he said. What Warren didnât expect was on Sept. 4 to be put in the same cell as an inmate who had just been exposed to COVID-19. The inmateâs old cellmate was sent to isolation the night before after testing positive for COVID-19, Warren said. Four days later, Warrenâs new cellmate also tested positive. Six days after that, Warren did too, he said.
