Thank you for the question.
I think, yes, the number of tests—and by that, I mean PCR tests—being done around the country has been reduced, but of course rapid tests have come into play. We don't have samples from those rapid tests in order to look for variants or sequencing, but there are quite a lot of samples being done every day from which we can do sequencing.
We are still sequencing at quite a high rate—at a rate at which we can detect more rare variants—but we need to keep this up. Of course, at the wastewater surveillance, we can actually, on top of doing viral copies, use metagenomics to look at variants in the wastewater.
