“…Two clades of mpox (previously known as monkeypox) virus, a member of the genus Orthopoxvirus in the family Poxviridae , caused until recently only limited zoonotic outbreaks in Africa [Elsayed et al, 2022; Gessain et al, 2022; Huang et al, 2022; Mitjà et al, 2022; Rabaan et al, 2022]. Currently, mpox viruses considered as clade IIB (occasionally also as clade III, consensus on the nomenclature is still developing) are spreading for the first time by sustained human-to-human transmission outside of Africa [Elsayed et al, 2022; Gessain et al, 2022; Huang et al, 2022; Mitjà et al, 2022; Rabaan et al, 2022]. This ongoing outbreak was classified as a ‘Public Health Emergency of International Concern’ by the WHO on 23 rd July 2022 [Elsayed et al, 2022; Gessain et al, 2022; Huang et al, 2022; Mitjà et al, 2022; Rabaan et al, 2022] and has at the time of writing (29th December 2022) affected at least 110 countries, accounting for 83,539 documented cases and at least 72 deaths [CDC, 2022].…”
