South African variant

[springisintheair2021]

I've been contacted by Public Health England to notify me that I have had the SA variant of Covid. Lots of questions about my contact were asked etc. I'm in an area where there have been no other SA variants diagnosed apparently.
The person who it's believed I contracted this from has also been contacted but I know little more.
My question to more informed people is will this variant have come from someone with the same variant or can it mutate from the Kent variant?

I think the answer is no, but there's a similar mutation that has happened to the Kent variant. You might like to post on the Data and Analysis coronavirus thread, someone there will know (and be interested to hear about your experience!).

Hope you remain(?) well OP.

Thanks I'll post there
I was terribly unwell for around 10 days but fortunately made a complete recovery despite being late 50's. ( I have no underlying health conditions but used to smoke quite heavily)
It's not an experience I'd want to have again!
