There has been a global outbreak of mpox since 2022; this outbreak has been caused by the strain of mpox virus called Clade 2 and has affected around 116 countries worldwide. The current surge in cases is being driven by the rapid spread of a different strain – Clade 1b – which is predominantly affecting countries across the African region, particularly DRC, Burundi, Kenya, Uganda and Rwanda [1]. The guidance in this document applies to both Clades of mpox. WHO publishes a dashboard of updated cases globally here. Different Clades and Sub-Clades of mpox behave slightly differently to each other; WHO is monitoring for any significant differences between the Clades, including transmission routes. This guidance will be updated as more information becomes available on this issue.
