The original concept was that a face cover thwarts propellents from travelling as far when expelled from the person. Thereby reducing the likliehood of droplets making it more than say, 2 feet (or less). And with another person standing say 4 feet away it meant viral load would not actually travel far enough to reach another person. Alpha, Beta, Delta…whatever.
Has this new variant somehow magically managed to become like smoke and just woft through the air despite the physical barrier of a face cover catching moisture droplets?
Has the CDC suddenly discovered (gasp) that inoculation or not it travels from person to person? That despite their best efforts, a large slice of the population does not have direct access to said inoculation? Particularly the disenfranchised community where many have to walk everywhere they go?
I still see about a 50/50 ratio of folks wearing face covers nearly everywhere I go. The troubling aspect is how many wear one while crossing the parking lot only to remove them when they arrive indoors. It's not uncommon to see people (alone) drive up and park their car wearing a face cover, walk to the building wearing the cover then removing it once they are in the congregate setting. That is completely backwards. But it's pretty common here where I live.
Viral load for
delta is immensely greater than the
alpha strain that was previously dominant, which combined with its tendency to produce breakthrough infections means that the vaccinated can spread it around even if asymptomatic.
The initial guidance on mask usage was - as we could easily deduct
then and know
now for certain - a gambit to keep citizens from snapping up all the medical-grade PPE before it could be diverted to the healthcare system. First the guidance was masks aren't necessary, then the slow pivot towards cloth/surgical masks, finally the obvious admission that superior media performs better than inferior filter media - even if worn imperfectly - but please please don't horde ≥N95 PPE.
Plenty of
logistical barriers to getting vaccinated - transportation as you have mentioned but also lack of internet access, lack of a smartphone, and the devilishly difficult task for many of taking time off work both in terms of securing permission and the pain of lost wages. That's in addition to the
conceptual hurdles that a large slice of the populace is facing.
Apparent mask usage is perhaps 10% in the small slice of the DFW area I roam around - and most of that is
establishment staff. Maybe it's the region's miserable heat ~6 months of the year, but pretty much no one is walking across parking lots with a mask on.
