Details and Analysis:
To date, the Johns Hopkins University & Medicine reports that there have been 4,511 confirmed cases of COVID-19 throughout the State of Arizona (up from 3,112 confirmed cases last week). This is a 45% increase in weekly confirmed cases, or an 6.5% average daily rise in confirmed cases over the last week. This represents a lower rate of rise of cases by ~25% in comparison to the previous week, and the rate of rise of cases has fallen for 3 consecutive weeks. The doubling rate of cases is 10.9 days, up from 8.1 days in the previous week, and is a sustained and favorable change. In comparison, there have been 706,856 confirmed cases of COVID-19 in the United States, up from 519,453 confirmed cases 1 week ago. This is a 36% increase in weekly confirmed cases, or an 5.1% average daily rise in confirmed cases over the last week, a lower rate of rise by ~50%, and a reduction in the average daily rise in confirmed cases in the United States for 3 consecutive weeks.
This data suggests that the rate of rise of confirmed COVID-19 cases in Arizona SUPERCEDES the national average, and reverses a previous trend.
There have been 127 recorded deaths in the State of Arizona due to COVID-19 (up from 71 deaths last week).

From the Arizona Office of the Governor:
On 31 March 2020, Arizona Gov. Doug Ducey (R) issued a Stay Home, Stay Healthy, Stay Connected Executive Order: Office of the Governor: Doug Ducey
“Keeping Arizonans safe and healthy as we slow the spread of COVID-19 remains our top priority. Arizona citizens and businesses are already responsibly responding to this crisis. This order builds on the state’s efforts to protect public health by reminding Arizonans to maintain healthy habits and find alternative ways to stay connected with friends and loved ones while spending time at home. Slowing the spread of COVID-19 will ensure we build capacity in our healthcare system, and help protect the lives of those we love most. It’s important to emphasize that there are no plans to shut down grocery stores. People should continue to buy what you need for a week’s worth of groceries. I’m grateful to everyone making adjustments to fight this virus and protect others. Arizona will get through this, and we’ll do it together.” — Arizona Gov. Doug Ducey (R)

As more schools announce closures and education administrators express staff shortages within their schools, now is the time to act. A statewide closure is the right thing to do. While this measure will not stop the spread of COVID-19, it will bring certainty and consistency in schools across Arizona.”— Arizona Gov. Doug Ducey (R)

While our state is not currently facing the number of cases we’ve seen in some other states, we are anticipating additional positive cases — and we’re not taking any chances. Arizonans should not panic — our approach will be calm and steady. This Emergency Declaration and Executive Order continue our effort to protect public health and save lives.” — Arizona Gov. Doug Ducey (R)
