That's good information, but do we have actual tests that can determine this variant from others that are being deployed at scale?

In other words, do we have any good reason to believe that the estimates of this variant prevalence compared to the other/original strains have any degree of accuracy and weren't just pulled out of someone's ass?

From my understanding we don't even have a particularly reliable test for the original SARS 2 coronavirus, that can distinguish it from other viruses or even false positives. Seems unlikely that we would have a test in mass circulation that can tell one variant vs the others.

Yes and no.

Any researcher worth the money could design a test specific to the Delta variant in about 20 minutes and have the reagents to run it in a day or two. Some group has obviously done this because not only do we know about the variant, we have the whole genome sequenced.

The PCR test that is currently used for the original Covid19 will also work for the Delta variant. If they run it out past 32 cycles, there will be massive false positives just like before. I know. I've done it.

The crux comes from telling the difference between the original and Delta. I would bet that the test for the Delta variant is not in wide-spread use. I don't actually know, but that seems like something the media would have a field day with. The fact that we haven't heard about it is telling. I suspect that the original PCR test is still being used with sporadic testing for the Delta variant specifically to confirm the outbreak.
