Hidden COVID cases in college crowds

Researchers recently checked how many university students carried COVID-19 without feeling sick. They picked a time when the virus was spreading slowly, so they could spot cases that might otherwise go unnoticed. The study wasn’t just about counting infections—it also looked at what put students at
