I think too many people are uninformed and scared. You are right that people need to be responsible and help control the spread. Unfortunately you have too many people who refuse to do simple things like wear a mask.
I have continued to work at the hospital since the beginning of this. I have had several close co-workers who tested positive for covid. This was before masks and face shields were recommended. After the implementation of masks and face shields all spread at work has stopped. I have cared for patients who are Covid positive while simply using a mask and face shield without spreading covid.
My sons daycare has been open since the beginning of this, we had 1 teacher test positive and but did not have a single other kid or teacher test positive after exposure. They take temps every morning. They do not let any parents in the daycare, teachers all wear masks all day, they clean thoroughly at the end of every day and they wash hands frequently. Heck they even have my 5 year old practicing wearing a mask 6 hours out of the day.
School could reopen if they had teachers either stand behind a shield, wear a face shield, wear a mask or any combo of this. All students could wear masks or face shields. All I know is that if a daycare with 250 kids aging from 0-9 (counting before and after program) can successfully navigate this, I know the schools would be able to.
