The SA variant case that seeded these cases probably arrived many weeks ago. Remember the first Kent variant case was traced back to mid September.
The good news is that the SA strain is unlikely to be more infectious than the Kent variant so is unlikely to take over for now. When we approach herd immunity the SA variant might takeover however as the Kent variant is more vulnerable to the vaccine.
Could it just be that there were some cases of the SA variant, but they were contained?
This news seemed to be cases which couldn't be linked, and thus would secondary infection from (probably) asymptomatic people?
