Here, we report the emergence of a new mpox lineage, named B.1.6.1. This lineage is native to Peru and has been reported mainly in young and adult men with immunocompromised systems. It is characterized by 5 mutations: OPG019 (Q81stop), OPG025 (A21T, E34K), OPG121 (S65L), OPG064 (M424I) and OPG210 (S1590F).
Lizarraga et al. (Mon,) studied this question.
