One of the things that we all need to keep in mind is that in the overwhelming number of cases COVID19 is not a killer. In fact, something under 20 or 15% experience sever reactions. Of those around 1% result in death. Add in the fact that the number of tests has increased by a factor in the thousands and we see numbers of infections that can be alarming. The reality is that yes, there are many people that are infected, but only a relatively low number will experience difficulty. That isn't much consolation for those that do react badly, but some consolation for the large majority that don't experience life threatening reactions.
I don't think it can be stopped, entirely, by "social distancing" but it sure can be slowed significantly. I felt bad for the folks stuck on cruise ships which were floating petrie dishes. Now we have a land based version with New York City. The pure concentration of population there makes it inevitable that a severe problem will happen there and is happening there. The same is true of all large population centers to one degree or another.
