Overview

Pathophysiology

Transmission

Monkeypox can be transmitted by[1]

  • Direct contact with body fluids or sores on the body of someone who has monkeypox
  • Direct contact with contaminated materials such as clothing or linens
  • Respiratory secretions when people have close, face-to-face contact

Genetics

  • Monkeypox virus is a member of orthopoxvirus genus, which is a subdivision of Chordopoxvirinae that belongs to family Poxviridae[2].
  • It is a linear double-stranded DNA virus that multiplies in the cytoplasm of infected cell[3].
  • All the proteins required for viral DNA replication, transcription, virion assembly, and egress are encoded by the MPXV genome.
  • The genes encoding for housekeeping functions are present in the central region of the genome, and the genes encoding the virus–host interactions are located in the termini region[4].
  • The nucleotide sequence within the central region of the monkeypox virus genome is 96.3% identical with that of smallpox virus. Nonetheless, monkeypox virus is not the direct ancestor of smallpox virus and is unlikely to naturally acquire all properties of smallpox virus[5].
