and if it's already been discussed before, forgive me, there are a lot of posts on here lately.

Why is 10 the number of people that is ok to have together?

Is it that with 10 people, the chance of one of them being infected is lower, and if they are infected they only give it to at most 9 other people at that gathering?
Is it that it's easier to keep something sanitized after they leave?
Is 10 random people a different risk than 10 people who are planning to get together?

I support any measure that will help us get through this with the fewest deaths. I support it even more when it seems balanced with keeping the economy going. I support it fully when it makes sense to me.

So if anyone can help me understand why 10 is the number, I'd appreciate it.
