Overview
Pathophysiology
Transmission
Animal-to-animal, animal-to-human, and human-to-human are all possible routes to transmit the disease. 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
Although most cases in 2022 were identified among men who have men with men, transmission of monkeypox via vaginal fluids or semen is still being investigated[2].
Genetics
- Monkeypox virus is a member of orthopoxvirus genus, which is a subdivision of Chordopoxvirinae that belongs to family Poxviridae[3].
- It is a linear double-stranded DNA virus that multiplies in the cytoplasm of infected cell[4].
- 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[5].
- 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[6].
