I'm moving to Portland oregon to a small neighborhood of fourteen autistic people in June. How likely am I to get Covid-19 from them?

Much more likely than if they had been to China. Covid-19 is much more common in the U.S. than in China.

The vast majority of cases are outside China at this point.

If they have a good setup in place, you wear a mask, and you frequently wash, you probably won't get it.

I literally jsut saw a facebook post about a  young white woman who apparently is itoa  doctor who ahs tested positive/ How could she ahve gotten it from, then? Everyone who has it has been in contact with someone who was in contacted with someone who who got it rom someone who ate a bat in China, right?
