Aytu is partnering with Cedar-Sinai hospital testing a device that will safely 'inject' UV light right into the lungs to treat Covid19 (and I would imagine other lung infections in the future) check out a video demo of it here. Sadly after the President mentioned UV light therapy in a presser Twitter suspended this publicly traded biotech companies account and Google/YouTube and Vimeo deleted this video.
