The potential risk is high, the actual risk is not there yet. There are 3 confirmed cases in Western PA. I'm not drastically altering my life yet for those odds.
I'm not worried about this personally (most shouldn't be). For sake of clarity though - the "confirmed" case numbers are demonstrably inaccurate. Testing is so limited in the US and across most of the world that only very specific people, and wealthy/influential people are being tested. Which is why there is a what would seem to be inordinate amount of high profile people infected. Celebrities, athletes, politicians, government workers are able to be tested outside the normal parameters and are frequently found to be infected despite no recent travel to an outbreak epicenter, a cruise, or even being fully symptomatic.
The point to all of that - there are millions of people infected right now, the true mortality rate is likely around typical flu - 0.1 to 0.2%.
So, unless this mutates, there really is nothing to be concerned about. It would be nice if someone other than Angie Merkel said this - you know, the WHO or CDC.
Only in South Korea and to a smaller extent China, did tests become available without such rigorous criteria. South Korea found thousands of people infected who would not be eligible for a test in Europe or N. America - a reason their mortality rate is just under 1% whereas Italy is 8%.

I work in a hospital - we are having about 75 people a day presenting with COVID (so they think and some are likely correct). We are testing only those who meet the high CDC criteria (exposure to confirmed case, travel to one of the 6 prime countries, or on the Grand Princess ship in last few weeks). So, we are testing 1-2 of 75 potential cases a day.
You should assume everyone around you is infected - most will show zero to very mild signs. You really should only be concerned if you have contact with folks over 70 and/or people with significant respiratory or kidney diseases. There is reason to be smart and cautious, but nothing beyond that.
