agreed , and add in other areas of need to kill pathogens(even before covid19)--agriculture, oil and gas...(gas will be a factor as I have read where trucks can convert to natural gas-cleaner burning)...we are at the start ... we just need the usa to open up for business-carefully, yes-yet open up ... 1 death is too many/60,000 died from the flu in 2017-18 and there is a flu shot...I got one--it does not cover all strains of the flu/my point-covid19 may spread more easily-true- medicines like hydroxychloriquine/with zinc and some that Israelis have shown to save people who were in very dire health from covid 19... need to be used-- masks etc. and safety protocol can be followed to insure safety--AND pctl-as they ramp up -will get noticed and used more and more...imo-EVERY BLDG. where people go should have the pctl system used for prevention--yes, even for the next pathogen that comes along-- imo-pctl would already be there for protection....best to use foresight now instead of what should have been done by gov't here/private business before this...

glta!
