COVID-19 cases linked to outbreaks on college campuses in Wisconsin increased rapidly in August 2020, and were followed by outbreaks at long-term care facilities, correctional facilities, and colleges/universities. From May 13–September 2, long-term care facilities (2,850 cases; 21%) and manufacturing or food processing facilities (2,672 cases; 20%) accounted for the largest number of outbreak-associated cases, and restaurants and bars (1,633 cases; 12%) and other workplaces (1,320 cases; 10%) accounted for an increasing proportion of outbreak-associated cases until mid-August. From September 3–November 16, 2020, daily confirmed cases rose at a rate of 24% per week, from a 7-day average of 674 to 6,426.
