For months, as New York City struggled to start part-time, in-person classes, fear grew that its 1,800 public schools would become vectors of coronavirus infection, a citywide archipelago of super-spreader sites.

But nearly three weeks into the in-person school year, early data from the city’s first effort at targeted testing has shown the opposite: a surprisingly small number of positive cases.

As campuses across the country struggle to carry on amid illnesses and outbreaks, a determined minority are beating the pandemic — at least for the moment — by holding infections to a minimum and allowing students to continue living in dorms and attend face-to-face classes.

Being located in small towns, having minimal Greek life and aggressively enforcing social-distancing measures all help in suppressing the contagion, experts say. But one major thread connects the most successful campuses: testing. Extensively.
