Report from Mexico
Have been in Puerto Vallarta, Cuernavaca, and Mexico City since December 18. Very little Covid here, although it's on the rise, as everywhere else. According to the New York Times map, Mexico currently has an average of 3.3 cases daily per 100,000 population, versus 120 in the United States. (But many probably unreported.) Most Mexicans are vaccinated with Astrazeneca, from what I can gather, and with two, not three vaccinations. Almost universally they wear masks, even in the open air, and even in cars. And 95 percent vaccination rate in Puerto Vallarta (pop. 220,000), where my wife's brother, a doctor, said they had had NO hospital admissions in three weeks (as of a week ago).
I customarily wear an N-95, either 3M make or Harley Commodity, both of which seem perfectly snug. Flying home tonight from Mexico City to Chicago on Aeromexico. Not anticipating any belligerent passengers starting fistfights.

trip with connections right when they should be. But keep the camera handy, just in case.
