Dear Friends,I read the following article https://scitechdaily.com/social-distancing-isnt-enough-to-prevent-infection-how-to-detect-covid-19-super-spreaders/ regarding Corona Virus aerosol transmission. One aspect of COVID19 infection management I have seen no reference to is the measurement of the amount of virus per volume of air. Is there no technology that will enable determination of virus, in both confined and unconfined spaces?[Mister] Bob FreedmanTucson, AZ
