We know coronavirus is transmitted by 1) droplet in air 2) touching a physically contaminated object by a coronavirus patient and then touch our face or mouth.

Now New York City got hit so hard, what is the primary transmission? 1) or 2) from above?

Also, let's say you pass a coronavirus patient in the supermarket, and he does not wear mask. What you can do to protect yourself?

    Does this answer your question? Actually what is the main way COVID-19 spreads? Have you bothered to look at any recent questions before asking your own? Mar 30 '20 at 4:28
  • The reason NY got hit so hard was because NY has the one of highest density of people living in the world, higher than HK, and it's a major international hub. And because they were not testing for community transmission so they got hit by a tsunami of community acquired infections. Mar 30 '20 at 5:53
