A new study suggests that reopening college campuses for in-person instruction may have fueled tens of thousands of additional coronavirus cases in the U.S. Researchers from several universities estimated that more than 3,000 new daily cases nationwide, on average, could be linked to colleges offering face-to-face classes, beginning around two weeks after instruction started. Campuses nationwide have attempted to bring students back this fall, but outbreaks have forced some to quarantine students or send them home and return to virtual courses.
