But what’s unusual about the surge is what’s happening in Chicago in particular, and how people in the city are getting infected with the virus at higher rate than anywhere else in Illinois. According to the data as of Christmas Day, the rate of COVID-19 infection in Chicago was 1,323.3 per 100,000 people, with the second highest rate being suburban Cook County with 1,175.5 per 100,000 people and the Will-Kankakee County region ranking third with 1,056.2 per 100,000.
