“…Most confirmed cases were concentrated in the southern zones, which are characterized as natural ecologic niches of monkeypox because of swamps and rain forests (2,4). Satellite imagery during 2000–2016 shows a substantial increase in built-up areas and farmland in southern Nigeria, created at the expense of these forested areas ( 28 ). This expansion of developed areas increases the likelihood of reservoir animals, such as rodents, rabbits, and primates, being displaced from their natural habitat and living among humans, thus increasing interspecies contact ( 29 ).…”

A monkeypox outbreak in Nigeria during 2017–2020 provides an illustrative case study for emerging zoonoses. We built a statistical model to simulate declining immunity from monkeypox at 2 levels: At the individual level, we used a constant rate of decline in immunity of 1.29% per year as smallpox vaccination rates fell. At the population level, the cohort of vaccinated residents decreased over time because of deaths and births. By 2016, only 10.1% of the total population in Nigeria was vaccinated against smallpox; the serologic immunity level was 25.7% among vaccinated persons and 2.6% in the overall population. The substantial resurgence of monkeypox in Nigeria in 2017 appears to have been driven by a combination of population growth, accumulation of unvaccinated cohorts, and decline in smallpox vaccine immunity. The expanding unvaccinated population means that entire households, not just children, are now more susceptible to monkeypox, increasing risk of human-to-human transmission.

, Nigeria has been experiencing the largest monkeypox outbreak in the country's history. As of November 2019, the country had reported 183 confi rmed cases across 18 states (1). This outbreak is also the largest recorded that has been caused by the West Africa clade of the monkeypox virus (MPXV). Beyond its scale, this outbreak is an illustrative case study for emerging zoonosis because of its epidemiologic characteristics. Preliminary genetic analysis suggests multiple zoonotic introductions from animal reservoirs into

“…Some of these states have, over the years, become the largest epicenter of confirmed cases in Nigeria (Figures 2 and 3) and serve as a natural ecological niche of monkeypox [10]. Satellite imagery has shown that there is increasing development in the southern region of Nigeria, which is made at the cost of these forests [17]. The increase in the development of these areas also increases the chances of animal reservoirs, such as rodents, rabbits, and primates, having lost their natural habitat to have increased contact with humans [18].…”

The emergence and reemergence of infectious diseases caused by viruses continue to be a major public health concern globally, affecting both humans and animals. One such disease is monkeypox, a zoonotic infection caused by the monkeypox virus (MPXV) that has recurred in sub-Saharan Africa over several decades. Notably, the 2022 outbreak of monkeypox in Nigeria follows a deadly outbreak in 2017, which was preceded by the disease’s first recorded outbreak in 1978. Epidemiological investigations in 2017 showed no apparent link between human monkeypox cases and the outbreak that year, indicating the potential existence of multiple sources of the virus and limited human-to-human transmission. This underscores the presence of an alternative ecological niche in humans. Furthermore, in some communities in Nigeria, monkeys are regarded as sacred and not hunted or consumed, leading to their proliferation and increased likelihood of MPXV transmission. This mini-review focuses on the occurrence, epidemiological distribution, geographical distribution, endemicity, and possible solutions to reduce the spread of human monkeypox in Nigeria. The implications of this reemergence and the need for effective public health measures to prevent and control outbreaks of monkeypox are also discussed.
