DETROIT – Detroit’s coronavirus (COVID-19) testing center will be moved from the fairgrounds to the Joseph Walker Williams Center starting Tuesday. The people who will be working at the testing center helped plan the transition. The reason the testing site will be moving from the State Fair Grounds is because colder temperatures are on the way. There will be 13 patients at a time able to fit inside of the location for testing. The center hopes to be able to maintain its clean record as far as the employees go.
