Not really. There are 20M people in the metro area and 421 positive tests so far. Assume (reasonably conservatively) that those tests reflect about 10% of the active infections, and that there are about 2x as many contagious but asymptomatic cases as sick people (both the doubling rate and the incubation period seem to be about 5-6 days). That's one potential transmission event per ~2500 people right now. You'd have to be on a lot of subway cars to be within infection distance of that many people.
It's close enough to be worried, but not at "going in public will make you sick" yet.
(Edit: covidtracking.com just pushed some new numbers, and NY is at 524 cases. Up 25% in a day is freakout territory -- a doubling period of just a little over 3 days. We have to hope this is an artifact of more testing capability or just a data burp.)
