It's likely too early in the history of BA.2 to know what it is going to do to people. For example, today I just learned that Omicron kills people much faster than Delta did and it appears we are losing just in the U.S. an average of 2200 people a day now to Omicron. Though Cases are decreasing in the northeast likely the number of deaths in the north east are just now peaking from omicron. So, for example, in California the death peak likely will be 2 to 4 weeks from now with around 50,000 a day getting Omicron now in California that are tested.
