The University of Arizona had its first day of in-person classes Monday as people on and off-campus worry that a rise in cases will inevitably follow students' return to Tucson. "We feel that we've done a very good job about creating an environment that's receptive to our students, staff and faculty returning in the increments we have explained. But they've got to adhere to those public health practices,” said Dr. Richard Carmona, head of the Campus Reentry Task Force and distinguished professor of public health.

Following a dramatic surge of coronavirus cases between June and July, numbers across the United States have largely decreased, which experts attribute to local mask mandates and other precautionary measures, like restaurant and bar closures.

Other states have seen a similar increase in deaths since the pandemic began, said Zhao Chen, a chronic disease epidemiologist and professor at the University of Arizona's Mel and Enid Zuckerman College of Public Health. Chen said Arizona's growing population could explain part of the increase in overall deaths, though she doubts growth is the only factor.
