History
Monkeypox was first identified as a distinct illness in 1958 among laboratory monkeys in Copenhagen, Denmark.
Agam Rao, a medical officer in the Division of Pathogens and High Consequence Pathology at the CDC, said that since 2018 all cases reported outside Africa have come from Nigeria.In a 2021 article Oyewale Tomori pointed out that the number of monkeypox infections in Nigeria through 2021 was likely to be under-represented, because much of the Nigerian population had been avoiding healthcare facilities due to fear of contracting COVID-19.In May 2022, the Nigerian government released a report stating that between 2017 and 2022, 558 cases were confirmed across 32 states and the Federal Capital Territory. The Rivers State was the most affected by monkeypox followed by Bayelsa and Lagos. There were 8 deaths reported, making for a 3.5% Case Fatality Ratio.
