How many children have died worldwide from covid? The figure in Australia is 0.
If you take Sweden, which has had a pretty heavy case count and highly reliable numbers on deaths and hospitalizations.
Total pop ca 10.4 mio. Confirmed case count so far is just north of 1 million. Actual number much higher. Antibody testing suggests that rougly 20% of the population has had Covid afaik, so that would indicate actual case count bit over double the number of confirmed cases in Sweden.
For 0-9 years they have 26k confirmed cases
For 10-19 years they have 128k confirmed cases.
0.6% of ICU patients are aged 10-19. (43 out of 7341)
0,4% are 0-9 years old. (32 out of 7341).
8 people aged 0-9 have died and 5 aged 10-19. Total deaths 14.217.
Don't know if they have changed their mind now, but if I recall correctly our folks said the regular flu was more dangerous for small children than covid-19 but that's a while back and they might have adjusted their take on it.
Not seen hospitalization data (ex-ICU) broken down by age group for Sweden so no idea on that.
