LANSING, Ill. (December 11, 2021) – Yesterday’s report from the Illinois Department of Public Health (IDPH) included 49,668 new confirmed and probable cases of coronavirus disease (COVID-19) in Illinois, including an increase of 266 deaths since December 3, 2021.

As of Thursday night, 3,257 individuals in Illinois were reported to be in the hospital with COVID-19. Of those, 662 patients were in the ICU and 299 patients with COVID-19 were on ventilators. Currently, IDPH is reporting a total of 1,884,744 cases, including 26,801 deaths, in 102 counties in Illinois.

A total of 18,007,906 vaccines have been administered in Illinois as of midnight Thursday, with 509,428 doses administered in the previous week. Approximately 70% of Illinois residents have received at least one COVID-19 vaccine dose, and more than 62% are fully vaccinated according to data from the Centers for Disease Control and Prevention (CDC). Approximately 41% of Illinois’ eligible adults have received a booster dose of vaccine.

IDPH recommends monoclonal antibodies therapy as a prevention and treatment option for COVID-19 illness for people who are non-hospitalized, explaining that it is a way to lower the chance of becoming severely ill. IDPH continues to encourage health care providers — including primary care offices, outpatient clinics, urgent care centers, infusion centers, dialysis centers, home health services, and hospitals — to assess their capabilities to provide this treatment to their patients quickly after a COVID-19 diagnosis, particularly when there is a risk for severe illness or hospitalization.

    • Eb, my guess is, that number is difficult to track because COVID manifests itself in so many different ways, with so many different symptoms, and so many different effects. Our reporter Carrie Steinweg, for example, is still feeling some effects of COVID a year after her diagnosis. Would she be considered “recovered” yet? And others are diagnosed but never have symptoms — are they considered recovered when a test comes back negative? I don’t know. Your question is a good one, but my guess is that the CDC and IDPH don’t provide those numbers in their reports because of the complications involved in gathering them.
