Trump Muses About Light as Remedy, but Also Disinfectant, Which Is Dangerous (nytimes.com) 670
President Trump has long pinned his hopes on the powers of sunlight to defeat the Covid-19 virus. He returned to that theme at the White House coronavirus briefing on Thursday, bringing in a science administrator to back up his assertions and eagerly theorizing about treatments involving the use of household disinfectant that would be dangerous if put inside the body, as well as the power of sunlight and ultraviolet light. From a report: After the administrator, William N. Bryan, the head of science at the Department of Homeland Security, told the briefing that the agency had tested how sunlight and disinfectants -- including bleach and alcohol -- can kill the coronavirus on surfaces in as little as 30 seconds, an excited Mr. Trump returned to the lectern. "Supposing we hit the body with a tremendous -- whether it's ultraviolet or just very powerful light," Mr. Trump said. "And I think you said that hasn't been checked, but we're going to test it?" he added, turning to Mr. Bryan, who had returned to his seat. "And then I said, supposing you brought the light inside the body, either through the skin or some other way."
Apparently reassured that the tests he was proposing would take place, Mr. Trump then theorized about the possible medical benefits of disinfectants in the fight against the virus. "And then I see the disinfectant where it knocks it out in a minute -- one minute -- and is there a way we can do something like that by injection inside, or almost a cleaning?" he asked. "Because you see it gets in the lungs and it does a tremendous number on the lungs, so it would be interesting to check that." Experts have long warned that ultraviolet lamps can harm humans if used improperly -- when the exposure is outside the body, much less inside. The link between ultraviolet light and skin cancer is well established. Bleach and other disinfectants may kill microbes but they also can kill humans if swallowed or if fumes are too powerful. That is why bottles of bleach and other disinfectants carry sharp warnings of ingestion dangers.
