If you are the kind who says, “You know, I'd mask on flights if WHO or the CDC said I should,” I guess you can now start masking on flights.

WHO urges travellers to wear masks as new COVID variant spreads

Countries should consider recommending that passengers wear masks on long-haul flights, given the rapid spread of the latest Omicron subvariant of COVID-19 in the United States, World Health Organization (WHO) officials said on Tuesday.

@augieray I wear an N95 all the time in airports and airplanes now and will continue to do so. I actually wonder why I never did that pre-covid. It makes so much sense because airports are full of viruses from all around the world and masking is a very minor inconvenience. I use well-fitted and comfortable N95 masks and forget I have one on most of the time. Pre-covid I had caught head colds while travelling rather regularly but not once since masking. It just makes sense.
