Since the emergence of 2022's monkeypox virus (MPXV) outbreak, it has been the heading of news and research articles that MPXV is being involving non-endemic areas after about its 80-year presence in endemic areas. Efforts are concentrated on understanding how MPXV has evolved to cause an epidemic. The book provides a comprehensive compendium of chapters on poxviruses in different domains. It concludes that the main problem we should deal with is not to address how MPXV has overcome the distance between non-endemic and endemic areas, but it is the non-cooperativity of logistics, research, and science in managing poxviruses' outbreaks.
