The Arizona Department of Health Services is reporting over 196,000 confirmed cases of COVID-19 as of Thursday morning.

According to ADHS, there are 196,280 cases and 4,684 deaths of the novel coronavirus in Arizona, up 723 and 50 from Wednesday, respectively. That marked the sixth straight day with under 1,000 daily new cases.

The number of cases could be higher because many people have not been tested, and some can be infected without feeling sick.

Maricopa County shows a case rate of 2,916 cases per 100,000 residents, using 2019 population estimates. The state rate is 2,697. Santa Cruz County has the highest at 5,830 cases per 100,000 residents.

As of Thursday morning, Arizona has the third-lowest R-naught in the nation at 0.84. The state previously had the lowest with a 0.77. Alabama currently has the lowest with 0.77. This is the average number of people who become infected by an infectious person. Less than 1.0 is ideal, officials say.

According to Johns Hopkins University data analyzed by The Associated Press, the seven-day rolling average of daily new cases in Arizona decreased from 2,082 new cases per day on Aug. 4 to 883 new cases per day on Aug. 18. The rolling average of daily deaths during the same period dropped from 62 to 47.

The coronavirus causes mild or moderate symptoms such as fever and cough for most people. The vast majority of people who are diagnosed with COVID-19 recover.

But for some — especially older adults and people with existing health problems — it can cause more severe illness including pneumonia, and death.
