摘要
The recently re-emerged mpox(monkeypox)virus that causes mpox disease is a member of genus Orthopoxvirus and has unprecedentedly spread worldwide.Numerous studies have contributed to our understanding of its evolution,pathophysiology,and clinical manifestations.The current outbreak of the mpox virus depicts its novel route of transmission as a new variant.However,the exact reason for its transition from an epidemic to a pandemic remains unclear.Furthermore,other poxviruses such as vaccinia virus,variola virus,and cowpox virus,also belong to the same genus,Orthopoxvirus.In the present review,our objective was to summarize the evidence on evolution,pathophysiology,and clinical manifestations of mpox virus and its related poxviruses.The present review would aid in a better understanding of the current circulating mpox virus and its differences from other poxviruses.In addition,the shared genetic factors contributing to virulence in these Orthopoxvirus highlight their evolutionary connections and genetic similarities.While they exhibit differences in virulence,studying these genetic relationships is crucial for understanding their biology,pathogenicity,and the development of effective vaccines and antiviral therapeutics to curb mpox disease.
