Cases grew exponentially in the following weeks, surpassing 4,000 cases a day by mid-October and hitting more than 12,000 a day by mid-November, while testing only increased incrementally. While testing in Illinois began to routinely top 70,000 per day in mid-September, daily new caseloads remained relatively low. is averaging nearly 190,000 new COVID-19 cases and more than 2,000 deaths daily – shattering the virus’s first wave records.Ĭontentions that more testing simply resulted in more cases undermine the crisis.
