It probably is working, but it also seems likely that locking everyone in their houses reduces spread -- so three weeks after lockdown, there are fewer sick people to find each day. It actually is likely that the decrease in cases is more dramatic than the numbers show -- now that the acute pressure on the healthcare system in New York has abated, they're probably detecting a higher percentage of their cases. (And on top of that, testing has begun increasing again -- we tested 127,000 people today, up from 107,000/day just 6 days ago.)
