PHOENIX (AP) — Arizona reported nearly 900 additional COVID-19 cases on Saturday, the largest reported daily increase in several weeks.

The Department of Health Services reported 894 additional cases and 13 additional deaths as the statewide case total increased to 224,978 and the death toll rose to 5,759.

Additional cases and deaths are added to statewide tallies as they are reported to health officials after occurring in days and weeks beforehand.

The 894 additional cases reported Saturday were the largest daily increase since Sept. 17-18 when those days' counts ballooned to 1,753 and 1,281, respectively, as the state changed its counting methodology and each day added hundreds of past antigen test results.

The state reported over 800 additional cases on Tuesday and Thursday and over 600 additional cases on Wednesday and Friday.

According to Johns Hopkins University data analyzed by The Associated Press, Arizona's seven-day rolling average of new cases has risen over the past two weeks, rising from 489 on Sept. 25 to 617 on Friday.

The state's seven-day rolling average of new deaths dropped from 19 to 8 during the same period.

The number of infections is thought to be far higher because many people have not been tested, and studies suggest people can be infected with the virus without feeling sick.

Gov. Doug Ducey's office tweeted Saturday that the number of COVID-19-related hospitalizations and COVID-19 patients' use of incentive care beds and ventilators in Arizona remained far below last July when Arizona was a national hot spot.

COVID-19-related hospitalizations in Arizona steadily dropped until mid September and then leveled off before increasing slightly more recently.

For most people, the new coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death. The vast majority of people recover.
