There are reports. Yet via FOIA request they cannot actually be provided when requested.

The top link I shared below the first image goes into detail on how they provide the isolate that they do provide to the labs.

Keep in mind Mike Adams has been arguing against people making the claim about it not being "isolated" up until this point. He was also one of those talking about the virus that would be named COVID for a couple of months before the CDC or WHO said anything about it.
