Since it's all reactive in the US, and strong measures only go into effect once an outbreak has started, it's no surprise that it's hard to contain the virus. And at this rate, infections will just keep doing a tour of America, wandering from one area (say Florida) where they belatedly start getting an outbreak reduced, to neighboring Georgia and Mississippi which weren't doing enough until cases rise and it's again late in the day to lock down and mandate masks.
When you see an outbreak starting in NYC, NJ should immediately stop bridge and tunnel traffic, and trains to NJ. Once an outbreak gets large in Florida, Georgia and Alabama/Miss should seal off their states and do lockdowns, tests, mask mandates, contact tracing. You start early, success isn't that difficult. You start late and it's a hot mess.
I thought this was obvious.
China locked down the whole of Hubei Province, instituted provincial lockdowns of varying degrees, and would up with 50K cases total outside of Hubei. 50K of 1.3B Chinese. The US is experiencing 50K cases per day 6 months into the epidemic.
