You can't just conjure the necessary tests up from nothing. Japan has also had problems with testing. No one is trying to "deny testing". It is a work in progress and is indeed ramping up.

The states with "local outbreaks" (NY, CA, WA) are the ones that told the CDC to get bent and did it anyway. It's everywhere, the states with low case numbers just aren't testing for it.

This is what I can't get people around me to understand.
No cases near me simply means no one has been tested for it at this point.
On a phone call the day after the C.D.C. and F.D.A. had told Dr. Chu to stop, officials relented, but only partially, the researchers recalled. They would allow the study’s laboratories to test cases and report the results only in future samples. They would need to use a new consent form that explicitly mentioned that results of the coronavirus tests might be shared with the local health department.

The problem is it's ramping up to where it should've been weeks (months?) ago. We're way behind.
