IDPH: More than 127,000 children age 5-11 have received a COVID-19 vaccine dose

The Illinois Department of Public Health reported 236 breakthrough COVID-19 hospitalizations for the past week, and 46 breakthrough deaths. It’s a 15% week-over-week decrease in breakthrough hospitalizations and a 19% week-over-week decrease in breakthrough deaths.

The breakthrough hospitalizations week-over-week decline come as Illinois has seen a sharp rise in COVID-19 hospitalizations, eclipsing more than 1,600 total active hospitalized patients for the first time in more than a month.

There have been 981 total breakthrough COVID-19 deaths in Illinois.

Analysis of new hospital admissions for covid-like illness in the state over the past week put breakthrough hospitalizations at 22.3% of all COVID-19 hospitalizations in Illinois in the past week, down from about 32.4% the week before. This means those who are not fully vaccinated made up 77.7% of COVID-19 hospital admissions in the past week. Breakthrough deaths accounted for 34.8% of all COVID-19 deaths in Illinois last week.

COVID-19-like illness is defined as a if a patient presents with a fever and either cough, difficulty breathing or is given a diagnosis of COVID-19.
