Impact of COVID-19 on foodborne illness in Africa - A perspective piece.

Food safety investments in Africa, through international donors or national programs, were primarily focused on the formal market sector. However, increasing consumer food safety concerns about foods sold in the growing informal food markets, the rising foodborne disease burden in Africa, and the emergence of COVID-19 have all made food safety a major concern and ultimately brought it to an inflection point in Africa. In addition, Data on foodborne disease outbreaks revealed a scarcity of reported cases before and during the pandemic. The lack of information on foodborne disease reporting in Africa translates into one of the reasons why food safety in Africa is becoming a rising subject matter. This perspective discusses the situation of food safety in Africa before and after the COVID-19 pandemic. Finally, challenges confronting ongoing efforts to improve food safety in the post-COVID era in Africa are summarized and highlighted.

Preventing the Next Pandemic through a Planetary Health Approach: A Focus on Key Drivers of Zoonosis

The ever-increasing global health impact of SARS-CoV-2-the etiological agent of coronavirus disease 2019 (COVID-19)-coupled with its socio-economic burden, has not only revealed the vulnerability of humanity to zoonotic pathogens of pandemic potential but also serves as a wake-up call for global health communities to rethink sustainable approaches towards preventing future pandemics. However, since the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) convened experts have declared that future pandemics are likely to be zoonotic in origin, it is imperative that we understand the key drivers of zoonosis such as biodiversity loss, climate change, wildlife consumption, and population mobility, as well as the scientific evidence underpinning them. In this article, we underscore the correlations of these drivers with the emergence and re-emergence of zoonosis. Consequently, we highlighted the need for multidisciplinary collaboration under the planetary health approach between researchers across the fields of environmental and human health to fill the knowledge and research gaps on key drivers of zoonosis. This is to prevent or limit future pandemics by protecting the natural systems of the Earth and its resources and safeguarding human and animal health.

Zoonotic Spillover in an Era of Rapid Deforestation of Tropical Areas and Unprecedented Wildlife Trafficking: Into the Wild

Rapid deforestation and unprecedented wildlife trafficking are important factors triggering the rate of zoonotic spillover from animals to humans. Consequently, this leads to the emergence and re-emergence of zoonotic infectious diseases among the human population. Deforestation is an important ecological disruption that leads to the loss of biodiversity. The loss of biodiversity results in the persistence of highest-quality hosts of zoonotic pathogens dominating the low-diversity communities, a process termed the dilution effect. Activities like intensive farming and logging that resulted in deforestation bring vulnerable people in close contact with these highest-quality reservoir hosts (wildlife). As a result of this vulnerability, there is an increased risk of spillover, leading to zoonotic infection in humans and eventually disease outbreaks during human–human transmission. One prominent example of a disease of wildlife origin is the ongoing SARS-CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus 2), even though the original source has not been found. Another important factor facilitating the risk of spillover and emergence of zoonotic infectious diseases is wildlife trafficking. This involves illegal hunting and trading of wildlife and their products, which increases the risk of spillover as a result of exchange of bodily fluids and bloodmeals between humans and wildlife during the hunting and butchering of animals' carcasses. Consequently, little or no hygiene protocol and poor handling practices during the wildlife-trade chain expose poachers, consumers, and local market sellers to the risk of zoonotic diseases. Despite the interventions on deforestation-induced spillover and wildlife trafficking-associated spillover, there are still knowledge and research gaps that need to be addressed towards preventing the outbreaks of future zoonotic infectious diseases. In response to this, there is a need for interdisciplinary and intersectoral collaborations among researchers from various fields as well as sectors in minimizing the risk of zoonotic spillover driven by deforestation and wildlife trafficking at the human–animal–environmental nexus. In addition, there is a need for integrated and unified evidence-based policy formulation that puts an end to deforestation and wildlife trafficking, especially in tropical areas such as Africa and Asia.

The Need to Prioritize Prevention of Viral Spillover in the Anthropopandemicene: A Message to Global Health Researchers and Policymakers

Increased anthropogenic activities including changes in land use and unrelenting ecosystem services related to animal husbandry, wildlife trade, and deforestation are driving the emergence of viral zoonosis. This is primarily due to human–animal interaction which is facilitating the spillover of viral zoonotic pathogens from animals (domestic and wildlife) to humans that could result in epidemics or pandemics. Scientific reports so far have revealed that viral epidemics and pandemics in recent years such as H1N1 Swine Influenza, H5N1 Avian Influenza, Ebola, Zika, Severe Acute Respiratory Syndrome (SARS), and the ongoing SARS-CoV-2 were all zoonotic, and their emergence has been linked with spillover events arising from human–animal interaction. This increased interaction and the increased spillover event could facilitate future pandemic risk, and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, 'IPBES';, has declared this 'the era of pandemics';. Furthermore, since future pandemics would be triggered by anthropogenic activities, we have called this 'anthropopandemicene';, i.e., an era of pandemics driven by anthropogenic activities. To minimize the risk of future pandemics, it is important to prioritize the prevention of viral spillover events. Here, we outline five priority areas for global health researchers and policymakers. These areas include improvement of biosecurity at livestock farms, imposing a moratorium or strictly banning wildlife trade that poses a public health risk, conservation of biodiversity by halting deforestation, investing in community-based research for infectious disease control, and strengthening community healthcare systems in precarious ecosystems and infectious diseases hotspots. Finally, we acknowledge the efforts of other renowned global and legally binding frameworks such as IHR, the Paris Agreement, and CITES with regard to addressing the public health risk of infectious diseases, and we provide recommendations for their improvement.
