Well over 20K confirmed cases in NYC alone but I suspect that number will pass 50K within two weeks. Being that it's likely only those who develop serious symptoms have been confirmed, probably over two million have it or have had it but did/will have mild symptoms. We still would need to flatten the curve though so the remainder of the population gets it over a period of months, rather than weeks, in order to not overwhelm hospitals. Assuming this scenario (i.e. that maybe 5 or 6 million people here get it) we'll probably have herd immunity sometime in the summer. At that point, there's no sense staying in lockdown, at least in NYC. However, it will still be making its rounds elsewhere, so travel within the US should remain highly restricted. I'm curious what the percent of mild/moderate cases will be in NYC? Being that the city is filthy, especially the subways, many of us probably have great immune systems. It wouldn't surprise me if moderate/mild cases here are well over the 95% seen elsewhere.
By the way, there's a possibility I already had it. When I went to the store on Friday March 9, a little girl coughed on me as I passed by. A few days later my urine smelled terrible, which has happened before when I've come down with something bad. Then I was nauseous for a few days, ran a low-grade fever, and had stomach discomfort. Maybe it was a mild case of COVID-19, maybe not. I appear to be better now, and my mom seems fine. Being that it seems my mom has a better immune system than me, she may well have had it and not had any symptoms. Hopefully in the coming weeks they start testing large numbers of people for antibodies. No point keeping people who already had it, and got over it, at home.
