OOPS, wrong place, but I can till ay youre fulla bird turds maxy.Perhaps youve been n another planet.(Or as I suspect you are just interminably denying that such research has NOT gone on anywhere in the world)
Earth to max
RESEARCH ON MASKS HAS BEEN DONE
They incorporated MATHEMATICS so you seem to only trust math and not experimental results of discovery .
Using guinea pigs en Mass, the researchers found that rats upgradient with the virus in their URS, would shed active virus particles to Target isolated cages downgradient.
1 Upgradient infected rats with No masks infected 100% of downgradient rats (They used fans to blow air from up gradient to down gradient at various distances downgradient)
2 when upgradient rats were outfitted with masks, an 85% protection was noted in the downgradient rat groups >AND the shed virus was of a much low concentration .(Infection level is a function of particle density, That was demonstrated also in steps 2
3when both upgradient rats (all shedding virus) AND downgradient rats were outfitted with masks, the downgradient rats had a 95% protection and a lower density of virus particles in the individual rats of several groupings of masked downgradient "target" rats. I think it was Lancet that published it (John Campbell lited the paper site but I didnt copy it down.
I sorta thought that we were all past the days when "reputable doctors" testified that cigarrettes DID NOT cause cancer.
MAx, youre not an epidemiologist. Neither am I. I liked the way the research was done and ,if you can find John Campbell's (epidemiologist whose been posting comment on daily infection , recovery, reserch, etc etc.
He was also showing pictures of the swimming pool party taken in Mo. No social distancing so masks would not have been any use without determining aerosol annd droplet distance when face to face.
Russian roulette uses rules of chance too,
Remember max , a mask is your caring about others not yourself. A mask interferes with YOUR droplets , so both parties must wear em to be effective to all.
Trumps insistance of NOT wearing a mask is the peak of uncaring during this times
