It's very important that we continue to monitor the genomics, the genomic sequencing, which is being done right now. The omicron virus continues to undergo evolution.
You've probably seen the various sublineages. In particular, right now we're monitoring three: the BA.2.12.1, the BA.4 and the BA.5, which have some immune escape properties as well as increased transmissibility.
Those variants could potentially cause an increase in activity. Even more importantly, we're watching out for some very different variants that may, just like omicron when it first started, have come from an immunocompromised host or even from animal sources. Those are even more concerning, and as yet we can't predict that, since it can happen by chance.
