How is it we're talking about this and not the concrete steps towards the millions of daily tests needed safely end social isolation?

I've received UVA and UVB phototherapies. To treat GVHD. Works great. Last I checked, no one really knows how or why.

UV is totally worth investigating.

It's totally inappropriate (dangerous) for the POTUS to speculate on TV during a pandemic. Especially while actively thwarting or malignecting actual proven useful treatments and mitigations.

Shame on media (and us) for the ongoing attempts to divine a coherent narrative from the blather of a madman.
