I've seen some very interesting treatments. The malaria drug hydrochloroquine and paired with azithromycin. Considering one is immunosuppressive anti-parasite. The other is antibacterial. They actual seem to be working.
Intravenous vitamin C also has some solid data behind helping patients in critical condition.
Plasma transfusions with people who've recovered from covid19, for their antibodies is underway right now. Will be exciting to see how this works.
Besides those 3 I'm not very familiar with any that sound promising or show signs of success. Please list what your aware of or might reccomend.
I've recently found out there's a microbiome in our lungs. I would like to see if there's any breathing treatments or lung bacteria transplants that could help.
