Confused by COVID case counts? Here's why numbers vary, says public health official

If you’re confused about the discrepancies in daily COVID-19 case reporting by the University of Illinois and the Champaign-Urbana Public Health District, you’re not alone. But there’s an important reason the daily totals don’t match, according to a public health official. Take Sept. 4, for example: That was a day the University of Illinois reported 104 new positive saliva tests on campus on the same day the Champaign-Urbana Public Health District reported 88 new positive cases for all of Champaign County.
