Can COVID testing keep high school sports and classes running?

Imagine trying to keep high school sports seasons alive and classrooms open during a pandemic. Schools in Utah tried something straightforward: they tested students for COVID-19. From late 2020 into early 2021, they tested nearly 60,000 high schoolers. About 3 out of every 100 students tested positive, which helped identify cases and likely prevented some spread. The big picture result? An estimated 95% of athletic events were completed, and schools saved over 100,000 student-days of in-person learning that might have been lost to quarantine. This is a real-world look at what happened when schools made testing available. It's important to remember this was an observational study—it simply recorded what occurred. The report doesn't compare these schools to others that didn't test, so we can't say for certain that the testing programs were the sole reason these activities continued. It shows a promising association during a difficult time, but more evidence would be needed to confirm a direct cause-and-effect relationship.
