specifically primary and secondary school, although university is an issue as well

i put this in a comment but:

i think the school issue is difficult. if you go back to school, you will have massive increases in cases and deaths. if you go online only, you put enormous pressure on parents - schools are responsible for feeding many children and often act as daycare. if you do a “hybrid” approach you’ll get the worst of both worlds, except it’ll likely be primarily lower-income children going to school and getting sick, plus more pressure on teachers.
