When Trump gave the speech about Hydroxychloroquine, he also mentioned "sunshine" and disinfectants (nebulized hydrogen peroxide has been used to kill pathogens in the lungs).
Of course the media went all jihad on HCQ, as did the medical establishment, and some idiot (?) killed her husband with aquarium cleaner, and somehow all that got morphed into drinking bleach.
Sure it works. some sunshine and your body makes vitamin D. Unless, of course, you have Lupus which can be aggravated by sunshine, but you might already be taking Hydroxychloroquine then...
