The Illinois Department of Public Health (IDPH) today, Thursday, October 15, 2020, reported 4,015 new confirmed cases of coronavirus disease (COVID-19) in Illinois, including 53 additional confirmed deaths. On September 4, 2020, IDPH reported 5,368 new cases of COVID-19 after a slowdown in data processing delayed reporting of some additional aggregate numbers. Cases not reported in the previous several days were included in the September 4, 2020 total. The slowdown did not affect the reporting of positive or negative results to individuals in any way.

Currently, IDPH is reporting a total of 331,620 cases, including 9,127 deaths, in 102 counties in Illinois. The age of cases ranges from younger than one to older than 100 years. The preliminary seven-day statewide positivity for cases as a percent of total test from October 9 – October 15 is 4.9%. Within the past 24 hours, laboratories have reported 67,086 specimens for a total of 6,531,009. As of last night, 1,932 people in Illinois were reported to be in the hospital with COVID-19. Of those, 388 patients were in the ICU and 147 patients with COVID-19 were on ventilators.

Starting today, Thursday, October 15, 2020, IDPH is including both molecular and antigen tests in the number of statewide total test performed in Illinois. Previously, due to the limited number of antigen tests and limited information about antigen test accuracy, antigen tests were not included in the total number (which comprised less than 1% of total tests performed). Antigen tests, like BinaxNOW™, are now becoming more readily available, therefore, IDPH will include both molecular and antigen tests in its total number of tests starting October 15, 2020.

Following guidance from the Centers for Disease Control and Prevention, IDPH is now reporting separately both confirmed and probable cases and deaths on its website. Reporting probable cases will help show the potential burden of COVID-19 illness and efficacy of population-based non-pharmaceutical interventions. IDPH will update these data once a week.

Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19)
