Reported COVID-19 cases in Arizona rose slightly from the week prior, and the percentage of tests returning positive for the virus was at 11%.
Percent positivity, which refers to the percentage of COVID-19 diagnostic tests that are positive, varies somewhat based on how it's measured. It was high in the winter months, a sign of more community spread. Then it was much lower but began climbing upward in April, and then back downward in recent weeks.
The state's overall COVID-19 death and case rates since Jan. 21, 2020, still remain among the worst in the country. Arizona's rate of fully vaccinated people out of the total population was 63.5%, which was behind the national rate of 67.9%, There's a wide range of vaccine uptake across the U.S. About 85.5% of the total population of Rhode Island was fully vaccinated, which is the highest rate in the U.S. In Wyoming, which has the lowest rate, just 52.1% of the population was fully vaccinated, per the CDC.
