Arizona has added over 700 new cases as of Friday morning.

According to the Arizona Department of Health Services, there are 204,681 cases and 5,171 deaths of the novel coronavirus in the state, up 728 and 41 from Thursday, respectively. Arizona had reported below 1,000 cases for nearly three weeks before the state added nearly 1,100 cases on Thursday.

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.

Maricopa County shows a case rate of 3,021 cases per 100,000 residents, using 2019 population estimates. The state rate is 2,812. Santa Cruz County has the highest at 5,959 cases per 100,000 residents.

As of Friday morning, Arizona has a R-naught of 1.01, according to rt.live. This is the average number of people who become infected by an infectious person. Less than 1.0 is ideal, officials say. Arizona had maintained an R-naught below 1.0 for weeks. Texas has the lowest with 0.84. West Virginia has the highest with 1.28.

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.
