I can only find the figure for 0-17 which is 258.
OK, so absolutely tragic for each and every one of those families, but not on the same scale as the number of children who have sadly passes away in Brazil.
I suspect that poverty is a major factor in explaining the difference. I sincerely hope that it isn't a case of the Brazilian variant being more dangerous for the young.
Either way, I feel terribly sad for all those families who have lost loved ones in this awful pandemic.
