36/gpc If I can simplify the science of SARS Corona Virus 2 (so far): (a)The virus comes out of an infected persons lungs & seems to accumulate in air till it& #39;s dispersed. (b) The severity of the infection seems to depend on the concentration of virus one breathes in? ....37/gpc
37/gpc (3) Anything which reduces concentration of virus near your nose reduces probability of infection & vice versa. So closed spaces with unfiltered, recirculated air & many unmasked people are worst, open spaces with breeze, low concentration of people wearing masks r safest
38/gpc (d) On supply side #TTQ reduces the likelihood of a random person you meet, having Covid & spewing virus in the air one is breathing. (e)Vaccination does the same, plus it #reduces the #probability of getting infected even if the concentration of virus in air is high.
39/gpc (f) The transmission of virus through material surfaces seems to be lower than thought earlier, but the solution is simple. Wash hands with soap if a stranger has touched something you are using, and/or let it sit in open air for a day
40/gpc In Indian summer w/o ACs, Air coolers which take fresh air from outside, cool it & blow it through room(s) & out of the windows, can help in reducing concentration of Viruses in air. In presence of strangers, Masks would still be needed & distancing while eating/drinking!
