Maybe not surprising news but some bad news relating to re-opening schools... (I think the second study was already mentioned here)
“In one study, published last week in the journal Science, a team analyzed data from two cities in China — Wuhan, where the virus first emerged, and Shanghai — and found that children were about a third as susceptible to coronavirus infection as adults were. But when schools were open, they found, children had about three times as many contacts as adults, and three times as many opportunities to become infected, essentially evening out their risk.
Based on their data, the researchers estimated that closing schools is not enough on its own to stop an outbreak, but it can reduce the surge by about 40 to 60 percent and slow the epidemic’s course.
The second study, by a group of German researchers, was more straightforward. The team tested children and adults and found that children who test positive harbor just as much virus as adults do — sometimes more — and so, presumably, are just as infectious...
They also estimated that closing schools can lower the reproduction number — again, the estimate of the number of infections tied to a single case — by about 0.3; an epidemic starts to grow exponentially once this metric tops 1...
A new study by the National Institutes of Health may help provide more information to guide decisions in the United States. The project, called Heros, will follow 6,000 people from 2,000 families and collect information on which children get infected with the virus and whether they pass it on to other family members.“
