Main Article

Figure 1

Geographic distribution of countries in Africa considered endemic for mpox caused by monkeypox virus clades I and II. Clade I (blue dot) and clade II (green dot) indicate historic imported mpox cases linked to mpox-endemic areas through known travel before 2022. Geographic separation of clades in Cameroon is approximate.
