ABC News

Since the University of Arizona opened its doors, more than 9,000 students, faculty and staff had been tested for COVID-19 and everyone on campus was wearing a mask. The school had even begun sampling its wastewater to quickly detect a potential hot spot. But the centerpiece in the school's preemptive battle against COVID-19 was the "Covid Watch" smartphone app, which uses Bluetooth technology to send an alert to someone's phone if they are exposed to the virus. University of Arizona professor and BIO5 member Dr Joyce Schroeder, led a team to help customize the app to not only alert a user of exposure, but also to inform them if their level of risk from exposure is high or low.
