transmission, meaning that it seems to be extending in the air for longer periods of time, for longer distances. it is more measles like than flu-like in terms of the transition pattern. there are two new varieties circulating in new york that seem to be more contagious than the b2 that we ve seen. there s this b6 mutation that seems to give the virus more ability to defeat the vaccines, at least the antibody response induced by existing vaccines. it is unclear if they will spread here. they have other mutations that make them less transmissible so it is unclear how transmissible these will be. this virus is evolving ways to make it slightly more contagious each time we get a new version of the omicron strain. again, the fact that the mutation is happening within the omicron lineage, that s what we thought would be the end game
