GG13, I have no special knowledge in this, just a scientific background in another area and an ability to read between the lines of news reports.
As growstuff says it doesn't matter who calls it what, but I know for sure that calling it "Deltacron" is more likely to cause alarm than calling it XYZ-123 or whatever its scientific name is.
I didn't see Bauld on TV, but I've got Sky on just now in case she comes on again. The only articles I have found online say that there are no large numbers of cases, there is no evidence that it is more or a concern than what we already have. We had a "deltacron" before, do you remember? Turned out to be nothing.
Now maybe this will be nothing and maybe it won't. But like Pantglas I'm a bit over the whole thing of "new variant, man the barricades!!" That's not putting my head in the sand, and its not ignoring the truth, its getting on with life.
