Monkeypox virus is an enveloped double-stranded DNA virus that causes the viral zoonosis monkeypox. Monkeypox virus is a close relative of smallpox virus and causes symptoms similar to those of smallpox virus, with fever, headache and other flu-like symptoms appearing first after infection, followed by blisters on the skin of the face and limbs after a few days. Monkeypox caused by monkeypox virus infection is a self-limiting disease, there is no specific drug, there is no need for special treatment, generally 2 to 4 weeks after the disease can be cured, but serious cases can also lead to death. Monkeypox virus can be transmitted through a large number of respiratory droplets containing poison, or through direct contact with the body fluids of infected persons or objects contaminated by the virus, such as clothing and bedding. However, it is much less contagious than smallpox and smallpox vaccination is effective in preventing monkeypox virus infection. If you are suspected to be infected with monkeypox virus, it is recommended that you seek prompt medical attention to avoid delays in diagnosis and treatment.
