Oh yeah. The worry that kids spread to adults. Yeah, that's not happening either.
Certainly.
Per this article - https://www.wsj.com/articles/why-its-mostly-safe-to-reopen-the-schools-11596812466:
In The Netherlands (reopened schools in May with no masks or distancing requirements) – “In a study of 54 families with Covid-19 by the Dutch National Institute for Public Health and the Environment, no child under 12 was found to be the “index” patient—that is, the first patient in the family. These results, the institute concluded, “confirm the impression that children do not play a significant role in the transmission of the virus”.”
In Iceland (normal fall reopen)– “A similar study by Icelandic researchers across the entire country’s population was published in June in the New England Journal of Medicine, with similar results. Kári Stefánsson, one of the leaders of the research group, said, “We have not found a single instance of a child infecting parents”.”
In Germany (reopened schools in May with some size/mask protocols) – ““The dynamics of virus spreading have been overestimated….[and] schools did not become hot spots after reopening,” the university wrote. Reinhard Berner, chief of the department of pediatrics at the university’s hospital, said, “We are going into the summer vacation of 2020 with an immunity status that is no different from that in March 2020,” adding that “children may even act as a brake on infection”.”
In France (reopened gradually over May/June w/masks only in high school) – “A study by researchers at Institut Pasteur of students ages 6–11 found that “there was no evidence of onwards transmission from children in the school setting”.”
Finland locked down, Sweden did not - “”Finland has not shown children to be contributing much in terms of transmission” to adults, and in Sweden there was “no increased risk for teachers”.”
“The totality of the evidence makes clear the compelling case for reopening schools for younger children. “It is extremely difficult to find any instance anywhere in the world…of a child [under 15] transmitting to a teacher in school,” observes Mark Woolhouse, an epidemiologist at the University of Edinburgh. The experience of school reopenings has been positive in countries that started with the youngest children, like the Netherlands, and those that started with the oldest children, like Germany. It has been positive in countries that mandated strict physical distancing in schools, like Denmark, and also in countries that did not, like Sweden. And it has been positive in countries where the pandemic has been as deadly as in the U.S. and also in countries where it has not.
The article notes that “The case for reopening high schools, however, is less definitive and requires more caution….And in all age groups, we must still take seriously the risk that teachers and school staff will transmit the coronavirus to each other, as we would in any other workplace or gathering space”.”
