Useita sars-cov-2 variantteja löytyy vielä ja muutamia ihan lähimailta Ruotsista, esim BA.5.2.20 alavarianttia

 https://github.com/cov-lineages/pango-designation/issues/1251

Tämä on pieni klusteri ja sillä ei ole vielä designaatiota, mutta se kuuluu BA.5 ryhmään ja  on BA.5.2.20 alalinjan  alalinja.  (GITHUB asia #1251 on käsittelynalainen, klusteri vielä pieni)

Sublineage of BA.5.2.20 with S:N148S, S:K150E, S:N334K, S:K444T, & ORF1a:E726K (9 seq) #1251

Evidence
It looks like a mini-saltation from BA.5.2.20 led to this lineage, most likely from a long-term infection in one individual. One of the nine sequences is placed earlier in the tree, without K444T, but it has zero RBM coverage, so it almost certainly belongs with the other eight, meaning all nine sequences here are identical. This suggests rapid growth, though numbers are too small to be sure about anything yet.

Six of the sequences here are from Stockholm, but three of the most recent four have been from Skane. Skane appears to be a county in the extreme south of Sweden, over 300 miles away from Stockholm, so it seems there has already been some geographic spread here.
