if you think the current Covid is the same as original Covid, then research more. It's not coincident that the Recovery:Death increasing everyday. (hint: D614G, parainfluenza type 4). The reason they dont care because you cant lock up people forever. Lets say you are good for now, how sure next flu season will be? if you are exposed for once, your t-cell will "remember" it, and herd community will be formed.
They re-close some states again, not because of the virus cases increase, its because of ICU is full of patients who have underline disease, or old age.
US got hit more severe because of China didnt stop flights out of its country + WHO didnt claim nation disaster. Remember, no where in the whole world has more ChinaTown compared to the US. if you know CHinese culture, you will know how important Lunar new year to them, and they come back their homeland every year for that ( around Jan). So they get hit more.
Currently, if you compare the peak of North states in US such as NY, NJ, ... they peak together with Europe, and now its over, the case is about the same as EU now.
Back in April, South States such as CA, FL,TX werent even starting yet. But now they are at peak. Compare the peaks, not the trough between regions.
I know its kinda nerdy comment, but i hope to add some knowledge to you.
