If you're from Seattle, then the recent research of Trevor Bedford (Fred Hutchinson Cancer Research Center) and the Seattle Flu Study group might be relevant - they've posted a quick summary on https://twitter.com/trvrb/status/1233971278735761409 while there's still the weekend; but in essence they've done genetic analysis of the Covid-19 strains in Washington sate, and it suggests the following worrying things:

1. their analysis (virus mutations / differences in individual patients?) suggests it has been spreading in Washington state for some 6 weeks already;

2. "Our best current expectation is a few hundred current infections" (that's about WA only! not the entire USA) - it's not confirmed and identified cases, but the number suggested by virus variation; it's not like there's 6 patients who have all been "imported" or form a single clear cluster, they have been infected by some patients who have not been identified, have not been isolated, and have been spreading it in the cummunity.

To me the situation in Washington State seems very similar to where Italy was a week ago.
