  • Monkeypox, caused by the monkeypox virus, is a viral infection that spreads through close contact. It typically causes flu-like symptoms and can lead to pus-filled lesions on the body.
  • The virus belongs to the Orthopoxvirus genus in the Poxviridae family. It is an enveloped double-stranded DNA virus and is related to viruses like vaccinia, cowpox, and variola (smallpox).

    • Clade 1: More severe, with up to 10% mortality rate among those infected.
    • Clade 2: Less severe, with over 99% recovery rate. The 2022 outbreak was caused by Clade 2.
  • Variants:
    • The current outbreak in Congo started with an endemic strain known as Clade I.
    • A new variant, Clade Ib, has emerged, showing increased spread among children.
