‘New ECDC guidance on testing for COVID-19 in schools says anyone who is in a “closed environment, such as a classroom, for more than 15 minutes” with a confirmed case is considered a close contact and should be tested’
So: kids catch the virus at the same rate, and transmit at the same rate as adults. They just don’t tend to become symptomatic as much as adults do.
This is a great article:
The outbreak has been studied comprehensively by scientists using genetic sequencing techniques. The index case, who was masked, spread the disease to co-workers in a radius of more than eight metres over three days of work shifts, they found. Transmission was aided by the confined area of the plant, where air was constantly recirculated and cooled to 10 degrees. Shared apartments, bedrooms or carpools did not play a major role in the initial outbreak.(Via Dee Gilhawley)
