I'm a physician but had forgotten my medical history (silver was used extensively prior to modern antibiotics). Maybe making a comeback given pervasive development of antibiotic resistance:
I remember I saw another company selling Silver based solution to be used internally. Maybe it didn't much sense to pursue this avenue before, but with the Covid - it should be pursued. Of course, they should just supply the SDC and let some pharmaceutical company do all the heavy lifting like testing and marketing. That would be a cherry on the pie.
