My sister's an ER doc in Baltimore and they're getting one mask per 12-hour shift. That quantity doesn't protect them from anything or their patients
I saw someone else post this on HN... Worth a look. http://www.imcclinics.com/english/index.php/news/view?id=83
They're also not getting eye protection at all so she's taken to wearing her glasses instead of contacts. Not as good as actual eye protection, but it's better than absolutely nothing.
In short, they don't have what they need.
