2017–2019 Nigeria outbreak
According to the Nigeria Centre for Disease Control (NCDC), between 1971 and 1978, only 10 human monkeypox infections were reported in the country.In September 2017, human monkeypox re-emerged in Nigeria, 39 years since it had been last reported. The subsequent 2017–18 Nigerian human monkeypox outbreak was, at that time, the largest ever outbreak of clade II of the virus, with 118 confirmed cases. Unlike previous outbreaks of this clade, infection was predominantly among young male adults and human-to-human transmission appears to have readily occurred. Seven deaths (5 male, 2 female, case fatality rate of 6%) were reported, including a baby and four HIV/AIDS patients. Additionally, a pregnant woman in her second trimester had a spontaneous miscarriage due to monkeypox infection.The Niger Delta University Teaching Hospital reported that a substantial number of its young adult cases had concomitant genital ulcers, syphilis and HIV infection. Monkeypox spread around southeast and south Nigeria with some states and the federal government of Nigeria seeking ways to contain it. By December 2017 it spread to Akwa Ibom, Abia, Bayelsa, Benue, Cross River, Delta, Edo, Ekiti, Enugu, Imo, Lagos, Nasarawa, Oyo, Plateau, Rivers and Federal Capital Territory. The outbreak started in September 2017 and remained ongoing across multiple states as of May 2019. The Centers for Disease Control and Prevention reported cases of American travelers contracting Monkeypox upon return from Lagos and Ibadan.
Cases were also reported in travellers to Israel and Singapore. The UK saw further cases in 2019 and 2021.In June 2022, the World Health Organization announced that it would find a new name for the disease, in line with its policy to avoid misleading associations with specific regions or animals.On 31 July 2022, the first death from monkeypox was recorded in India: a 22-year-old man who had returned from the UAE died.
