The Monkeypox virus, commonly abbreviated as mpox, is a viral zoonosis that is experiencing a resurgence in prevalence. It is endemic to regions of West and Central Africa that are characterized by dense forested areas. Various measures pertaining to animals, humans, and the environment have been recognized as potential factors and catalysts for the spread of the disease throughout the impacted regions of Africa. This study examines the various factors contributing to the transmission of the virus in Nigeria, with a particular focus on the animal-human and inter-human modes of transmission in rural communities and healthcare facilities. The One Health approach was emphasized as crucial in the prevention and management of this issue. Literature suggests that preventing repeated zoonotic introductions could potentially halt the transmission of the mpox virus from animal to human hosts, leading to a potential decrease in human infections.

Over the years, the nations of the world have been plagued with several infectious diseases outbreak. With the continuous rise in the number of emerging and re-emerging infectious diseases such as monkeypox, it is high time we drew lessons and insights from past outbreaks to guide and effectively prepare for possible future outbreaks. Monkeypox, popularly known as the most important orthopoxvirus infection, is a viral zoonotic disease prevalent in Central and West Africa. There are 2 known genetic clades of the monkeypox virus reported so far, the Western African and the Central African clades. The human monkeypox though originated from Africa has grown to be a global concern with cases reported in the United States, United Kingdom, Israel, and Singapore. It is distinctively characterized by lymphadenopathy and systemic rash symptoms. Monkeypox has a low fatality rate (0-11%) with the highest rates occurring in children and young persons who were not part of the smallpox vaccinated population. Report suggests that consumption of bush meats could be a potential risk factor in the transmission of the infection or caring for an infected patient. Several factors have been responsible for the weak surveillance system of monkeypox including the current COVID-19 pandemic that has put more pressure on the fragile healthcare systems and infrastructures of most countries. This paper aims to guide global health policymakers on the impending danger of neglecting this disease. The discourse is concluded with the recommendation of strategies to effectively strengthen the disease surveillance system in combating this public health threat.

Nutritional immunity is a major facet of host defense, wherein the host immune system strategically limits pathogen access to critical nutrients, including iron, zinc, vitamins, lipids, and amino acids, to repress microbial proliferation and virulence. This review provides a comprehensive synthesis of the molecular mechanisms that power nutrient immunity, including metal homeostasis, nutrient competition, transporter modulation, hormonal regulation, and direct antimicrobial actions. We examine nutrient-specific strategies employed by the host, such as iron-withholding mechanisms, vitamin deprivation, and copper-mediated toxicity. We also explore how diverse pathogens, including extracellular, intracellular, and eukaryotic pathogens, adapt to these hostile nutritional landscapes through siderophore diversification, regulatory integration, and metabolic rewiring. Comparative genomic analyses reveal convergent evolution in nutrient acquisition systems, illuminating the dynamic arms race between host restriction and microbial evasion. We examine the immunological mechanisms that regulate nutritional immunity. Further, we discuss the translational potential of nutritional immunity, cutting across nutrient-based therapies, host-directed interventions, and emerging diagnostic biomarkers. Finally, we suggest future directions that synergize nutritional immunity with microbiome ecology, global malnutrition, and personalized medicine. By elucidating the interconnection between metabolism and immunity, this review highlights the therapeutic promise of starving or toxifying the pathogen to save the host.

The reemergence of the monkeypox (MPX) virus poses a serious threat to global health security. While the first human case was reported in Democratic Republic of Congo in 1970, a recent outbreak of this disease in May 2022 has gone ‘viral,’ spreading to most continents and occurring in nonendemic countries. Outside Africa, there have been reports of cases of MPX in countries such as Singapore in May 2019, Israel in September 2018, UK in September 2018, among others which have been traced back to importation of infected wild rodents from Africa. The Centers for Disease Control and Prevention (CDC) recommends that the standard laboratory facility to carry out MPX tests is Biosafety Containment Level (BSL)-2 working standards if the laboratory staff has taken smallpox vaccine within the last 3 years and BSL-3 working standards if the laboratory staff has not taken the smallpox vaccine. However, African countries have a shortage of BSL laboratories. Hence, there is a need to improve the integrated surveillance of the MPX virus, strengthen diagnostic capacity, capacity building of health workforce, public education programs, fund research, and development, among others. Leveraging a ‘One Health’ approach will offer fresh insight into the human–animal–environment interface and boost the understanding on the possibility and mechanisms of spillback and reverse zoonosis as well as disease severity and risk factors for severe disease as well as its epidemiology in various subpopulations. Not leaving Africa behind in the prevention, diagnosis, and management of MPX is important to stopping the spread and reemergence of this virus.
