The person may have been vaccinated - other cases of this strain where in people who were fully vaccinated but got it anyways. (A lot of people who are fully vaccinated let their guard down. Although it doesn’t matter how careful you are, if the people around you aren’t.)
I also kind of wonder if this is a selection bias issue - that maybe they were specifically testing travelers from Southern Africa for the variant, and found it in one of those travelers, but they’re ignoring all the people who might have gotten infected domestically, or brought it in from somewhere other than Africa. It would be dumb if that’s what they’ve been doing, given the odds are significant that it didn’t originate in South Africa - they found some cases that are weeks old in Europe, they simply hadn’t been doing the genetic analysis and testing that South Africa has been, and weren’t looking for it until S.A. brought up the issue. They traced cases in Israel back to the UK.
@Mangochin
It’s so fast it’s going back in time. They’re retroactively discovering new cases around the world (i.e. that they simply hadn’t been aware of at the time).
