The First Felon’s speech at CPAC included the complaint that children are not back in school yet, adding a fillip implying that the reason is incompetence on the part of Joe Biden. But, according to Science magazine:
Keeping schools open in Sweden roughly doubled the risk that teachers would be diagnosed with the pandemic coronavirus in spring 2020, a study has found. It also raised the infection rate for their partners at home by 29% and for parents whose children attended in person by 17%, the authors reported on 11 February in the Proceedings of the National Academy of Sciences.
Children might not be so susceptible to the Coronavirus sickness as the adults who surround them, that is, but they clearly are efficient carriers.
It is too soon for schools to re-open.
