For clarity: there are multiple ways variants can emerge, and reducing virus circulation so the @#!! can't keep exploring the @#!! fitness landscape is great! But variants don't always come from "abroad": they can arise in single individual with long-term infection here as well.

That’s interesting & matches up intuitively for me since most people are only infectious during such a short period regardless of length of illness. My money is on the asymptomatic carriers.

this maps onto what
@BillHanage has been worried about no? -
Yes, a few papers on this. It just seems important to highlight this both for clinical practice (so such patients are followed-up appropriately) and also to remind people "over there" isn't necessarily the only problem/source for variants.
