Background: Human monkeypox was a neglected zoonotic disease considered endemic to rainforests of rural parts of Central and Western Africa, until a global outbreak in May 2022.
Methods: This review describes the epidemiological characteristics of human monkeypox.
Results: Since the first confirmed case in the United Kingdom on 13 May 2022, and up until 19 September, more than 62,000 cases of human monkeypox were reported in 104 countries in the world (among them 97 countries where the monkeypox virus was not endemic). Up to today, 20 persons have died in this global outbreak. This outbreak predominantly affects men self-identifying as gay or bisexual or other men who have sex with men, and for now, there is no sign of continuous transmission of the disease in other populations. Today, the monkeypox outbreak is increasing alarmingly in many countries and presents a new challenge and a large issue for public health worldwide. The World Health Organization declared the global monkeypox outbreak a public health emergency of international concern on 24 July 2022. Before this outbreak, health professionals in many countries had a knowledge gap and a lack of experience in the management of monkeypox.
Conclusions: Advances in the comprehension of the epidemiology of human monkeypox are necessary for effective prevention and outbreak response.
