Dr. Keith Jerome, head of the virology department at the University of Washington, is cautiously optimistic that, despite a newly identified sub-variant of omicron (BA.2), COVID-19 is reaching an endemic state.

The term “endemic state” refers to enough people gaining protection from COVID through a combination of vaccination and natural immunity, resulting in fewer COVID-linked hospitalizations and deaths.

鈥淭here’s every chance that this is the pathway toward getting to what we call an endemic state, where we all kind of live with this because everybody’s had the vaccine or a couple of bouts of infection, and even the people who decided to not get the vaccine now have their immunity 鈥� if they survive the infection,鈥� Jerome said on Seattle’s Morning News with Dave Ross and Colleen O’Brien.

鈥淪o where life gets a little bit back to normal, that’s certainly possible. But I do think that the people declaring that the end [of the pandemic] is nigh 鈥� might be a little premature.鈥�

The Washington State Department of Health confirmed the presence of the sub-variant of omicron in the state on Jan. 25.

鈥淏A.2 first started to get in substantial numbers in India and the Philippines,鈥� Jerome continued. 鈥淣ow, we’re seeing it grow in Europe — in places like Denmark ,the UK, and Germany. And we’ve seen it here. It seems to be growing.鈥�

The virologist addressed what the UW knows about the sub-variant of omicron, and just how dangerous it might be if contracted.

鈥淭he general sense is that BA.2 is probably even a tad more infectious than BA.1 (omicron). It will probably become the predominant version of omicron,” he said. “There鈥檚 no evidence right now that it’s any more severe, so that’s good news. But this is a super infectious virus that’s going to be more infectious.鈥�

He confirmed that modeling by UW Medicine predicts that the peak of, although the virology rate is still 鈥渦nprecedented,鈥� and the potential for a subsequent COVID variant could bring case levels back up, were it to arise.

鈥淭he idea is that the omicron peak has probably passed in many parts of the country,鈥� Jerome added. 鈥淚 think we’re maybe seeing a turn here.”

鈥淥ur positivity rates in the UW Medicine virology department are still over 30%, which is unprecedented in any other way.鈥�

鈥淪ome of the predictions say this is going to drop off, and we’re going to start to move toward this level of endemicity. I think that could certainly happen,” Dr. Jerome said. “I also know that biology is always hard to predict, and somewhere in the world maybe somebody with a smoldering, long-term infection is developing some new variant that we’re just not aware of yet. That’s the sort of thing that keeps me up awake at night. And that’s why we need to have as many people protected as we possibly can.鈥�
