A new peer-reviewed study from the American Academy of Pediatrics found that in-school transmission of COVID-19 is “extremely rare.”

In a collaborative study between Duke University and the University of North Carolina-Chapel Hill, researchers discovered that among 11 school districts with nearly 100,000 staff and students, there were no instances of children passing the coronavirus to adults during in-person instruction. Researchers found just 32 cases of either kid-to-kid or adult-to-adult coronavirus transmission over nine weeks.
