Introduction
In general, monkeypox virus is a DNA virus. In daily life, precautions should be taken to avoid contact with animals that may carry the monkeypox virus, as well as their secretions and excretions. If one has been exposed to individuals with monkeypox or potentially contaminated items, prompt personal hygiene and disinfection are essential. If symptoms such as fever or rash—suggestive of monkeypox—increase, immediate medical attention should be sought, and exposure history must be disclosed to prevent further spread of the virus.

Under normal circumstances, the monkeypox virus is a DNA virus. The detailed analysis is as follows:

The genetic material carried within monkeypox virus particles is deoxyribonucleic acid (DNA). In terms of viral classification, the monkeypox virus belongs to the genus Orthopoxvirus in the family Poxviridae. Viruses in this genus generally use DNA as their genetic material, with a double-stranded linear DNA genome that has relatively stable structure and a more robust error-correction mechanism during replication—this fundamentally differs from viruses that use RNA as their genetic material. Additionally, when replicating inside host cells, the monkeypox virus relies on its own DNA polymerase to complete DNA replication, rather than depending on the host cell's RNA-based replication system, further confirming its identity as a DNA virus.

In daily life, it is important to avoid contact with animals that may carry the monkeypox virus, as well as their secretions and excretions. If you have been exposed to individuals with monkeypox or potentially contaminated items, promptly perform personal hygiene and disinfection. If symptoms such as fever or rash appear, seek medical attention immediately and inform healthcare providers of your exposure history to prevent further spread of the virus.
