locally, here in the tucson area, (pima county), the county has about 1 million residents. and in the age group 0 thru 20 there have been No deaths. None. from covid.
yet some local leaders act as though they are afraid to open schools, and they need to protect kids. yes, kids can get sick from covid, but their mortality rate is nothing to worry about.
when it comes to covid, you only need to worry about the older teachers.
