The COVID variants Pirola (BA.2.86) as well as Eris (EG.5.1) are spreading faster and faster. Especially Pirola which seems to be even more easily transmissible than all other Corona mutations.
SARS-CoV-2 variant biology: immune escape, transmission and fitness
In this Review, the authors summarize the literature on the relative transmissibility and antigenicity of SARS-CoV-2 variants, the role of mutations at the furin spike cleavage site and of non-spike proteins, the potential importance of recombination to virus success, and SARS-CoV-2 evolution in the context of T cells, innate immunity and population immunity.
