Again oracle, you are incorrect. To contract a disease [the over whelming majority of people] you have to take in enough above a critical threshold which is different according to different viruses. It is a factor in determining how contagious a disease is classified as being. Covid is highly contagious, including variants but in room the size of a supermarket with the degree of dispersion in the volume and the rapid dispersion due to air conditioning, the threshold is just not reached. What the air borne build up is specifically referring to is small enclosed spaces with long contact times. That is why the advice to open a window and ventilation was included in the advice very late in the day, in fact only a matter of weeks ago.
Concentrated dabs from the mask are way over the threshold for many carriers, especially those who put the mask on when they leave the hose, wear it driving to the supermarket, and inside. If that person also has spluttering symptoms, they are spreading highly concentrated dabs all over the place.
I believe the four hour survival refers to how long the virus was found to survive on the surfaces of cardboard boxes and other packages when the possibility of importing the virus on parcels was examined. Some countries which were processing hubs quarantined all incoming parcels until they were convinced the virus only lasted a few hours in the open on surfaces. It caused huge chaos and delays into the months for consignments that should have taken a couple of weeks. I remember it well.
It is all academic anyway. Nobody is listening to the real science, only to what is convenient for positions they have adopted and intend to stick by. It is madness, sheer utter madness what is going on now. Unlocking was the path to get past the mask wearing without anybody loosing too much face. But no, some are so scared of what will be revealed they want to impose masks in perpetuity. Madness. If all those deaths wasn't enough, no the entire travel and holiday sector will be demolished just so a few idiots can save face.
