Mona points out that we manage the pendemic with a medical mind set instead of an engineering mind set. And as michael mina points out, that may be part of the problem. I would also extend that to the drinking blech hoax? How do you get that drinking bleach hoax? Well, when trump was speculating about, can you do something to insert a disinfectant into the lungs, he was talking about light. He he started the conversation telling you it was about light, and then he brought it back to light. That's sort of an engineering approach to a medical problem.
