Schools and children not a significant source of Covid

See Masks for Children, Muzzles for Covid-19 News: In the guise of combating ‘misinformation,’ YouTube again censors scientific debate over pandemic policy by Jay Bhattacharya. Excerpts:

"Florida reopened in May and declined to shut down again. Yet age-adjusted mortality is lower in Florida than in locked-down California, and Florida’s public schools are almost all open, while California’s aren’t."

"The scientific evidence is clear. Consider a study from Iceland conducted early in the epidemic when masking was uncommon. The study used a representative sample to track the source of Covid infections. The authors used contact-tracing methods paired with genetic sequencing analysis to establish precisely how the disease spread. The senior author of the study, Kari Stefansson, later told reporters that “even if children do get infected, they are less likely to transmit the disease to others than adults. We have not found a single instance of a child infecting parents.” Many studies in the scientific literature reach a similar conclusion: Even unmasked children pose less of a risk for disease spread than adults.

Consider also data from Sweden, published in the New England Journal of Medicine in February. Swedish primary schools have been open for in-person instruction throughout the epidemic, no masks required, even when cases were increasing. Of more than 1.8 million children in school in spring 2020 ages 1 through 15, not one died from Covid-19. This study also showed that teachers were at low risk for Covid; they contracted the disease at rates lower than the average of other Swedish essential workers."
