COVID cases remain on a plateau across Arizona. For the week ending May 2, cases dropped for the first time since the week ending March 21, with 4,946 people testing positive, according to Dr. Joe Gerald, an epidemiologist and professor in the UA Zuckerman College of Public Health who has been tracking the virus for more than a year. That means an estimated 68 Arizonans per 100,000 residents are testing positive. The state hit a low of 38 cases per 100,000 people on Sept. 8, 2020, between the summer and winter waves, and a low of 54 cases per 100,000 people on March 23 following the winter wave, with cases rising since then.
