Additional information could have been gathered by the Copenhagen study. 1) To what degree was social distancing being practiced. 2) While slightly fewer (but not statistically significant) people wearing masks got sick, how severe was the degree of illness reached by the people in each group. If one was inhaling fewer viruses, then the body’s zinc would have a better chance to fight the virus and the body would not progress to severe symptoms. Since seafood is probably a common food in Sweden, I wonder what the body zinc levels are in that population. Elsewhere I have seen that one third of the Earth’s population is zinc deficient. Null and void, please be sure you are getting a lot of zinc, and if not HCQ, then Quercetin which you can get at health food stores. Also, perhaps Resviratrol.
I’ve got quercitin, zinc, vitamins C & D, NAC and beta carotene.
You have to be careful with supplemental zinc. I do take it (25 mg picolinate) but with 50 mg or more daily you can end up with copper deficiency. So if you combine a zinc supplement with a multivitamin with significant zinc you could be in the danger zone.
