Having served with the US Army chemical corps short of MOP4 level personal protective equipment an airborne particle spread virus with proven formite transmission via particle settling and a fecal oral route there is little people with average protective skills and equipment can do other than avoid contact with an infected or an infected surface. Full face respirators with double silicone seals and filtering at a level of N99,or P100 would be the absolute minimum to effectively prevent inoculation in a challenged environment. Short of that level it’s kabuki theater.
My view of “The Science” is that a 528 ft. anti-social distancing would be pretty effective.
Indeed it is.
