The U.S. has granted emergency authorization for convalescent plasma, but experts say the science around the treatment isn't settled. University of Arizona College of Medicine – Tucson researcher and ICU medical director Christian Bime isn’t concerned about political pressure – out of confidence in the scientists embedded in the process. "I trust scientists to do the right thing," Bime said. "The stakes are too high and the consequences too dire for scientists to not follow best practice."

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.

"A thermometer that is cost-effective, reliable and easily cleaned between uses makes a thermometer good for families," said Dr. Farshad Fani Marvasti, director of the public health curriculum for the University of Arizona College of Medicine – Phoenix.

Arizona's COVID-19 reproduction number – a measure of whether a disease is spreading or contracting, also called R0 – is the lowest in the nation, by one count, just eight weeks after the state was in headlines as a coronavirus hot spot. But University of Arizona epidemiologist Purnima Madhivanan from the Mel and Enid Zuckerman College of Public Health, urged caution at the R0 news.

Arizona has seen a 20% increase in deaths in the first seven months of this year – and not all of them have been directly linked to the coronavirus. 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.

Deadly overdoses from all drugs have been on an upward trajectory in Pima County since March, the same month when the pandemic entered the forefront. The timing likely isn’t a coincidence, as Arizona 360 heard from Todd Vanderahan, head of the University of Arizona Department of Pharmacology at the College of Medicine - Tucson and serves as director for the UA’s new Comprehensive Pain and Addiction Center.

Classes and work are resuming, but many things have changed to make campus life as safe as possible.
