My daughter attended SBISD here in Houston where masks were optional the last couple of years and no teacher, administrator or janitor died because of infection due to Covid. None of the kids wore masks and they were always in person classes, no online. Only a handful even had it. I can only speak from our experience here. Your area may of been different/worse.
Here is the results of 2 years of studying covid infections of kids in Ontario (from the Government of Ontario):
* Children account for 12.9% of the 545,398 confirmed COVID-19 cases reported in Ontario, yet
they account for 18.7% of the Ontario population.
* The cumulative rate of infection among children is approximately 1.6 times lower (2,523.7 per
100,000) than adults (3,932.0 per 100,000). Among children, rates were highest (3,367.6 per
100,000) for 14 to 17 years olds.
* The most frequently reported acquisition exposure type among cases in children was close
contact with a confirmed case (53,103 cases, 75.7%). In contrast, the proportion of children
reporting a link to an outbreak setting was low (6,239 cases, 8.9%).
* The proportion of severe outcomes, including hospitalizations, ICU admission, deaths and
complications are much lower among cases in children compared to adults. Two deaths have
been reported in children compared to 9,255 deaths reported among adults.
