[Epidemiological, clinical characteristics, prevention, and control of monkeypox].

The World Health Organization officially declared that monkeypox was public health emergency of international concern on July 23, 2022. Current research shows that the clades of monkeypox virus are still Clade Ⅱ in multiple countries in 2022. Monkeypox cases are mainly males, with a wide range of ages. Compared with the population in previous studies, the reported population in 2022 had an increased median age, and the proportion of men who have sex with men increased. Monkeypox is usually a self-limited disease, with fever and rash as the primary clinical symptoms. Studies had shown that compared with before 2022, the proportion of fever in 2022 decreased, and the leading site of rash changed from cheek to genital mucosa. Asymptomatic monkeypox cases were first reported in 2022. Although there are no monkeypox local cases in China and imported risk is low, with the deepening of trade exchanges between countries in the world and frequent personnel exchanges, China should pay attention to the progress of the international epidemic and make efforts on emergency response, to prevent the possible occurrence and spread of cases.
