my Sonicare toothbrush has a chamber where you place the brush head that bathes it with UV light to disinfect it. I've had this for years so when President Trump made the comment on UV light I knew it was already proven to work to kill germs.
It was only a matter of getting the light into the body to make it effective. Looks like this Respiratory Catheter answers the question on how to get the UV inside the body where the virus resides.
suck it DUmmies, you were wrong again
