Anti-body tests a few months ago showed that about 25% of NYC residents already had the virus. I expect that percentage is even higher now. That's not the percentage needed for full herd immunity, but it's enough to substantially slow the spread if someone does have it. If the goal is to prevent any person from ever getting it again, then there's probably nowhere safe to reopen, but if we stick to the original goal of flattening the curve and spreading the infection rate over a longer period of time to prevent the healthcare system from getting overwhelmed, New York is in great shape and there's no reason we can't reopen. Granted, reopening in the city is tough because everyone rides public transit and so many places are tightly packed, but at a certain point we have to consider the long term health of the city, both medical and economic. Restaurants that have been there for 100 years are closing, crime is way up, and there's a looming eviction crisis that could devastate the poorest New Yorkers. I'm honestly concerned that NYC will go back to being what it was in the 70's and 80's if we don't reopen soon. As long as the healthcare system can handle an uptick in cases, which I think it definitely can at this point, we have to balance minimizing coronavirus against other priorities, like making sure more people don't lose their homes, their livelihoods, and their healthcare.
