My bet is the .gov found the "leaker".
-001 mentioned some things I was concerned could compromise him.
The .gov is clamping down hard on all Ncov info and rumor is all social media will be forced to delete all Ncov related info/posts very soon.
As -001 said, the gov knows what is coming and are doing everything they can to prevent panic as long as possible.
Locking down info is crucial in that aspect.
