Covid, a study to understand how lethal it was for children

Covid infection is rarely fatal in children and adolescents, but quantifying the risk of death is difficult, because in the age group 0-18 when one becomes infected (the prevalence of infection in this group has been estimated between 4 and 6% in December 2020) it is very likely that you will not experience any symptoms. This means that, for children, current estimates of the lethality rate (ie the ratio of the number of deaths to the number of infected) are not reliable.
