Sweden left their schools open. No children died and their parents could go to work. From Arjun Walia at lewrockwell.com:
What Happened: A letter to the editor published in the New England Journal of Medicine titled “Open Schools, Covid-19, and Child and Teacher Morbidity in Sweden” has found that “Despite Sweden’s having kept schools and preschools open, we found a low incidence of severe Covid-19 among schoolchildren and children of preschool age during the SARS-CoV-2 pandemic…No child with Covid-19 died…Among the 1,951,905 million children who were 1 to 16 years of age, 15 children had Covid-19, MIS-C, or both conditions and were admitted to an ICU, which is equal to 1 child in 130,000.”
Sweden was one of the few countries that decided to keep schools open. The study points out that the number of deaths from any cause among the 1,951,905 children in Sweden (as of December 31, 2019) who were 1 to 16 years of age was 65 during the pre-Covid-19 period of November 2019 through February of 2020 was 65, and 69 during 4 months of exposure to Covid-19 between March and June of 2020. The data shows that there was no significant difference here.
