Arizona numbers:

State hospitalizations and ventilators in use reach new highs.

Arizona reported another 4,057 COVID-19 cases and 75 more known deaths on Thursday as hospitals continue to see high numbers of patients.

Inpatient hospitalizations and ventilators in use by suspected and confirmed COVID-19 patients both hit new records on Wednesday, according to hospital data reported to the state. Emergency room visits and ICU beds in use hovered just short of the record high numbers reached on Tuesday.

Thursday’s dashboard shows 87% of current inpatient beds and 89% of ICU beds were in use, which includes people being treated for COVID-19 and other patients. Most people who get the disease are not hospitalized.

Identified cases rose to 112,671 and known deaths total 2,038, according to the daily report by the Arizona Department of Health Services. The state does not report the number of recovered cases, though it does report hospital discharges.

The 75 additional known deaths reported on Thursday represent the new deaths identified by the Health Department that day, but deaths could have occurred weeks prior and on different days.
