@Decency, transmission is very clustered. A city or a country can be ok one day, and not OK another day.
I did not hear about any cases in the community for several months, but then one family visited relatives in NYC and sent multiple kids to several school next week. Everything closed down for a couple of weeks. How far transmission is going depends really on how close kids and parents were in contact with others.
So, if you are a member of similar community with not many cases and connections to general population, you can either be careful all the time, or establish an early warning system where people report cases and be ready with maybe 10-20 people getting sick and everyone else getting back to careless life in 2 weeks. Ask your Rav what is better,
