It won't go away from just quarantining. It's impossible to get the contact rate low enough to prevent the spread of the virus to the extent where it would just cease to exist. Opening anything up will just repeat in cases rising again, there's no way around it.
It's either
1) Quarantine till vaccine comes out (queue epic economic meltdown, mass suicides, mental illness going through the roof and people losing everything)
2) Continue reopening shit slowly and re-close until necessary until vaccine comes out. Enforce mask-usage in high density locations and actually get information out there rather than having retarded news outlets like CNN, Fox and other bias networks put out horseshit that is politically motivated. Never imagined a fucking virus being politicized eh.

USA sits at #1 in testing with ~35m tests.
The number of people infected worldwide is exponentially higher, just the USA is testing a fuck ton more than any other country.
