The causative agent of monkeypox is a virus belonging to the poxvirus family. It was first isolated in 1958 from sick monkeys. It is similar in structure and properties to the human pox virus. Studies have shown that monkeypox virus is antigenically more similar to variola virus than to vaccine and vaccinia viruses. It grows well and multiplies in the shell of chicken embryos. Monkeys are the source of the infection, but there have been cases when the infection was transmitted from humans. Basically, this disease is diagnosed in patients under the age of 16 years.

The total duration of the disease is 2-3 weeks.
