Did COVID-19 spread fast on a college campus despite safety rules?

Imagine a university doing everything it's supposed to do to keep students safe from COVID-19. This report from a campus in North Carolina shows that even with measures in place that matched CDC guidance for colleges, the virus still spread quickly. The report doesn't tell us how many people got sick or exactly how fast it moved, but the clear finding is that transmission happened rapidly. Because this is an observational report—not a controlled experiment—we can't pinpoint what caused the spread or compare it to campuses that did things differently. It serves as a sobering reminder that in dense, social environments, containing this virus remains incredibly difficult, even with recommended precautions.
