MBB & WBB: New Covid Cancellations and Fan Restrictions From what I've read on these things, the more contagious a variant is, the less deadly it is, which is what we're seeing with Omicron. Makes sense because if it's more deadly, it kills people before it can spread as much. Less deadly means people don't get nearly as sick and therefore the virus can spread easier.
And that tracks with the stats movielover posted. Omicron cases shot up out of nowhere and in some places, have started to drop dramatically also. Hospitalization and death rates have been much lower than Delta. One thing I saw was that Omicron spreads in the upper respiratory system but not the lungs, which is where it does the most damage.
We'll have to see what the next variant brings though.
