📍NEW “BA2” SUB-VARIANT—@UKHSA has designated a #Omicron sub-lineage, known as BA.2, as a new “variant under investigation”. 53 in 🇬🇧 but 2,093 sequences of BA.2 recorded from 22 countries. Unclear yet—but “possibility it could be more transmissible.” 🧵 https://t.co/EPpktbuqzR— Eric Feigl-Ding (@DrEricDing) January 21, 2022
Yeah they're different things, with a causative link. Immune evasion causes higher transmissibility.
It makes things worse because more people get infected, and because people who were immune to the previous variant can now be infected and damaged again by the new variant.
More infections also creates more opportunity for more dangerous mutations.
