I just flew from SC to NY yesterday. I entered the Savannah airport not knowing which way the local rules would tip, but it was as follows: Very few people working (gate agents, TSA, staff) were wearing masks. Most passengers were not. Some in each category were, but it was the minority. Pilot announced that masks were no longer mandatory, and nearly everyone clapped/cheered. Once I got to Dulles for connection, the number of people masking was much higher, perhaps around 65%. I think compliance will largely follow regional tendencies.
During a trip to HI in January I had the pleasure of meeting a traveling immunologist. We discussed the stringent mandates in HI, and the effectiveness of masking. I had to ask her opinion. Her take was as follows: "When I'm asked to mask, this is what I use (and she holds up a beaded fashion mask, clearly not medical grade). It satisfies the 'requirements', as nearly all the mask mandates are ineffective unless it's true N95+ with zero contact with another surface (e.g. hands, so no removal/re-use etc). The only thing truly effective is your immune system as this virus mutates to something less lethal, so either get the vaccine or get covid and let your body deal with it". I thought it was interesting as I always prefer to get information from something other than media. I also know a respiratory therapist who specifically was sent in to NY to help deal with COVID cases during the heat of the crisis, and HE won't even get vaccinated. My point here is not what to do/not to do, but that as much as there are varying statements of "fact" from outside sources, there are differing opinions on what works/doesn't even from those deep in the trenches of working with the virus. I think as this unfolds further people should have the right and feel comfortable doing what is in their best interests to protect themselves.
