Our schools are planning similar to the Italian schools, and our Covid rates are similar to the UK in my US state.
They will be streaming lessons from the classroom for the cohort that are home (they are allowing half the students to come into school at a time).
Teachers who can't come into school for health reasons will teach the students who choose online-only education.
Laptops have been provided to all students and teachers, and wifi hotspots or free internet to those who don't have internet already.
Masks being worn by everyone who can wear them.
The idea is that schools need to be kept as safe as possible, but also that they need a backup plan in place for if/when there are Covid cases in school that result in closure.
If these plans were not in place, I suspect most people would just not send their kids back to school.
For an example of what can happen when you do allow a lot of people to congregate without masking, there was a 65-person wedding reception in a very rural part of my state a few weeks ago.
So far nearly 80 people have been infected as a result, one person (who did not go to the wedding) has died, and Covid has got into a nursing home resulting in 6 infections there, and into a county jail resulting in 18 infections there. People infected have ranged from age 4 to 90.
That's the sort of thing we're trying to avoid.
