I am going to stick with this bit of your link
But the science is far from settled. The
US Centers for Disease Control and Prevention says kids “can still pass this virus onto others who may be at higher risk, including older adults and people who have serious underlying medical conditions.” And
other studies show children continue to display similar transmission abilities as adults, leading experts to caution against trusting kids not to spread the disease
It makes no sense what you say about it not being the kids but parents picking them up from school,we won't learn everything based on primary schools alone ,what about all the other age groups at school,if I go with kids not transmitting it then what about when they get to 15/16, more adult than children
