What usually is the most lucrative time of the year for retail businesses along the U.S.-Mexico border could become another nail in the coffin for owners who already were grappling with a decrease in shoppers crossing from Mexico and other impacts from COVID-19.

Dr. Daniel Derksen, University of Arizona Health Sciences associate vice president, said he encourages every Arizonan to “take a look, shop and compare” coverage plans available through the ACA.

Since launching its COVID-19 exposure notification app in August, the University of Arizona claimed Thursday that its high usage rates have reduced “the average number of people infected on campus” by as much as 12%. “A 12% reduction in transmission doesn’t just mean you have a reduction in that next wave of cases but every subsequent wave of cases,” Mel and Enid Zuckerman College of Public Health professor Kacey Ernst said in a press release. “If one in eight can benefit from this, that’s pretty good.“
