I noticed this statement in the article:
“Because omicron is so contagious and
I imagine we have more contagious variants in our future,..." (italics mine).
So, they are talking about it becoming endemic. It will be like getting a cold or the flu.
Reading the whole article, IMO they were addressing primarily people who have not been vaccinated, saying, you can't dodge it, and the effect could be very serious if you are unvaxxed. It's the same message that is being given by all the US officials from Biden on down, to try to increase vaccination rates.
However, there are predictions that a significant portion of the population will catch it: "we could be having a million cases a day if we're not really attentive to all of those mitigation strategies," the outgoing National Institutes of Health Director Frances Collins told NPR
Omicron is now the dominant COVID strain in the U.S., making up 73% of new infections
A wave of 3-4 months, peaking at 1 million cases per day, that could be 50 million cases (assuming far fewer people will get tested if their symptoms are mild). The current total cases in the US is 52 million.
