Features of the Emergence and Re-Emergence of Infectious Diseases, Geopolitics and Gain-of-Function Research

In recent decades, there have been exacerbating outbreaks of infectious diseases with grave emergence and reemergence worldwide. These incorporate the severe acute respiratory syndrome coronaviruses ^{1, 2}, swine flu, Middle East respiratory syndrome coronavirus, the Zika virus and the Ebola virus disease disseminating across international boundaries; thus, ushering in an era of unprecedented climate, demographic and technologic spatiotemporal variations ¹ in both rural and urban precincts with escalating threats to hunger/food security, environment, health and socioeconomic activities ^{1, 3, 4}. These pose grave threats which require countries with vast resources and conscionable geopolitical imperatives to contribute and enhance global health and environmental security to stem the increased risk in the emergence and reemergence of novel infectious diseases ^{5, 6, 7}.

All nations continue facing the threats of an avalanche of emerging and reemerging infectious disease epidemics and pandemics. These have resulted in widespread escalating global concerns due to their excruciating and debilitating effects ^{1, 8}; with the inextricable linkage of infectious diseases and geopolitical stability without an iota of consideration for international boundaries or borders.

Understanding geopolitical determinants and gain-of-function research will enhance evidence and imperatives for the improvement of preventing and treating emerging and reemerging infectious diseases globally. Protagonists of international health, policy and security have perspicuously enhanced health perspectives and interventions in association with political stability and gain-of-function studies to address the disproportionate global perturbations and impact of the SARS-CoV-2 Omicron variant and other microbial variants as they reflect on strategies to balance public and medical modalities in the pandemic devoid of stigmatisation regarding the origin(s)/source(s) as in HIV/AIDS controversies ⁹.

Gain-of-Function research is capable of exposing perspicuous mutation occurring in defined viruses, permits easier community surveillance, and identification of the genesis of the mutations, contemporaneous production of compatible and veritable vaccines ^{6, 7} and feasible treatments. Thus GoF research connotes the serial presentation of microorganisms whereby their host tropisms, immunogenicity and virulence are augmented via the inducement of specific pressure to a defined culture ¹⁰. CRISPR, a gene editing technology is feasible coupled with selective serial passaging in the investigation of the functionality of defined genes on protein expression and roles of organisms as well as the biological mechanisms undergirding the transmission and replication of viruses ¹⁰. Nascent SARS-CoV-2 variants having mutations in the spike glycoprotein emanated independently in numerous locales within ostensibly significant functionalities. These aggregated mutations in the 501Y, K417N and E484K were detected in the receptor-binding domain, RBD including mutations in the N-terminal domain, NTD ¹¹. The nascent SARS-CoV-2 or COVID-19 Omicron variant, B.1.1.529 (Nu, Xi) was detected through genomic sequencing.

Exploration of vaccines and treatment modalities as well as trending strategic scenarios in the context and perspective of erstwhile epidemics and pandemics provides valuable applications for the prevention, control and treatment of emerging and reemerging infectious diseases. This means an upward review for inter alia compulsory application of face masks, practical sustained manual hygiene, social distancing, assembly in well-ventilated ambients and other pertinent non-pharmacological interventions, compliance to preventative strategies to restrict the dissemination of the newfangled variants ^{6, 7} per gain-of-function research and geopolitical interventions. Statistical equivalence tend to indicate that vaccines have been protective against the presenting coronavirus variants. The mRNA vaccines by Moderna and Pfizer-BioNtech are more effective than the Astrazeneca variety. Animals are liable to contract SARS-CoV-2, and viral reservoirs can revert same to humans. However, the pharmaceutical industries are faced with paucity of data in the choice of viruses for immunization. A newfangled oral antiviral drug, Molnupiravir for the effective treatment of the COVID has been produced by the Merck and Ridgeback Biotherapeutics ¹², and it is incumbent on developed countries with abundant resources to distribute these vaccines to poorer countries and vulnerable populations worldwide ^{6, 7}.

Due to emerging variants, the COVID-19 pandemic has placed the production of a veritable vaccine in an intricately complex situation as the pharmaceutical industries have limited data for the immunization against any particular coronavirus. It is considered that the gain-of-function research whereby there is certain genetic manipulation culminated in more deleterious delta variant of SARS-CoV-2, the etiologic agent of COVID-19 ^{6, 7}. Although, this remains speculative, the gain-of-function standard on the conspiracy and collaboration of China and the NIH of USA will be protracted even as the source, origin, socioeconomics, geopolitics and legal implications of SARS-CoV-2 are sustained or controverted by gain-of-function research of concern, GOFROC as a discretionary term ¹³.

With regard to pharmaceutical drugs, Ibuprofen, also called Advil and Motrin is a common non-steroidal anti-inflammatory anti-pyretic therapeutic agent, additionally used for pain mitigation, fever, swelling and redness ¹⁴. It was suggested that ibuprofen was an inappropriate treatment for certain symptoms in COVID-19 patients because SARS-CoV-2 was detected to bind to target cells through ACE2 in the respiratory apparatus ¹⁵. Thus, it was suggested that ACE2-stimulating drugs, ACE inhibitors and ibuprofen aggravate the risk in the severity of morbidity and mortality of COVID-19 ¹⁶; and, as such, not amenable in COVID-19 suspected cases ¹⁷. However, it has not been proven that ibuprofen is associated with symptom derangement, prolongs illness, or that resultant or concomitant inflammations mask COVID-19 severity, interfere in certain immune response or elevate the viral infection ¹⁴. These controversies that ibuprofen and other NSAIDs are not veritable choices in the treatment of symptoms in COVID-19 patients may be related to bias of retrospective short-term studies. Armchair scientists, researchers and medical practitioners are liable to misinterpret, misrepresent, omit or mislead authentic bioinformatics and spatiotemporal variations ^{1, 14} geopolitical activities and gain-of-function in SARS-CoV-2 or COVID-19 emerging and reemerging variants. The unpredictable and unprecedented accelerated dissemination of these nascent problems present novel challenges and opportunities for the production, formulation, administration and regulation of vaccines and other therapeutic pharmacological and non-pharmacological approaches ^{6, 7, 14, 18}.

Socioeconomic, natural, anthropogenic and other related constructed systems, such as geopolitics and gain-in-function research modalities have contributed to deleterious effects of certain microorganisms including the HIV/AIDS and COVID-19 or SARS-CoV-2 pandemic. These have impacted on the environment, social welfare, wellbeing and quality of life, biodiversity, ecological systems, governmental policy, governance ¹⁹, ecosystem cadastre ³, primary healthcare structure ^{20, 21} with concomitant social hysteria ²² in this COVID-19 pandemic era. These are presenting expansive effects of epidemics and pandemics across domestic and international borders or boundaries of countries or regions which have altered the trajectories of emerging and reemerging infectious diseases. The eradication or mitigation of upsurge in variants of infectious diseases may discontinue ecological interference of diverse epidemics and pandemics, such as HIV/AIDS, coronavirus, Cryptosporidium, Cystoisospora, Acanthamoeba, Ebola virus, Lassa fever, and yellow fever infections and infestations ¹. Contributing factors to emerging and reemerging infectious diseases include expansive increase of human population, migration, rapid increases in internecine conflicts, hunger ²³, geopolitical situations, deforestation, and abuse of pharmacological agents ^{24, 25} as well as the complexity of interactive events of anthropogenic and natural interplay in the emergence of novel microbial agents, and reemergence of erstwhile infectious diseases presumed to have been eradicated. Natural occurrences and anthropogenic activities have expansively contributed to facilitate the emergence, reemergence and dissemination of infectious diseases both locally and globally with their extant constraints and challenges as they fit into the environmental, public health, sociological, economic, salient and latent spatiotemporal and pecuniary burdens ²² associated with developmental and geopolitical activities.

Researchers tend to agree that within the past four decades, there have been remarkable global perspectives in taking cognizance and responding to threats of infectious diseases and harmful microbiota, especially since the SARS outbreak of 2003 ^{1, 26, 27}. The geopolitics of the presenting COVID-19 pandemic intersects in an inextricably complex global and transboundary trajectory that challenges global governance, policy and international cooperation. The COVID-19 pandemic has exposed the inherent dangers in the frailty and fragility of international cooperation of discrete and disparate national boundaries and territorial integrities or other collective responsibilities for sharing and distributing public health supplies, deciding on local and global strategic issues, excoriating and exacerbating pressures on food security ²⁸, vaccines ^{6, 7}, scarce resources ^{29, 30}, disruption of population density and climate change, especially in the least developed countries. These also pertain to the developed countries with the hardest hit of the COVID-19 pandemic exposed to environmental perturbations, such as poor atmospheric/air quality, public health and climate issues or challenges for coordinated response in a multidimensional strategy ³¹.

The immunodeficiency syndrome is a presentation of relatively inextricably-linked severe disorders due to the human immunodeficieny virus, HIV-1 ⁹. AIDS is mainly a disorder in erstwhile healthy persons without perspicuous underlying iatrogenic etiology. Controversies have been enmeshed in the origin ³², incidence anD prevalence of HIV, the social implications ⁹ and legal status have been extensively debated ³³. Devoid of effective and efficient vaccination, there will be incessant dissemination of the AIDS virus across international boundaries worldwide, there is no extant conclusive evidence that the AIDS virus emanated from sub-Saharan Africa, or that the progenitor virus was extant in Central Africa ⁹. Even by 2030; the African region may not terminate the AIDS scourge as a public health threat because the continent continues to fall short of the pertinent 75% dimunition in nascent HIV infections and 81% 2020 dimunition in AIDS-associated mortality ³⁴. These are evident, although, a vast majority of persons are aware of their HIV status and treatment schedules or rates. Nascent HIV infections and AIDS-associated mortality are not concomitantly diminishing. The African continent, and especially, the sub-Saharan Africa sub-region cannot afford to be detracted in the urgent quest and focus to curb the inequities which conduct AIDS, other epidemics and pandemics. Despite the challenges and issues, it is evident that remarkable progress has been achieved or achievable against HIV in recent decades and in the future regarding the decrement of morbidity and mortality rates in the entire continent due to ardent and strigent measures as well as consumption of antiretroviral drugs. It is imperative to employ equitable access to treatment, uninterrupted services, global sharing and solidarity which constitute essential ingredients to harness and curb HIV/AIDS, COVID-19 or SARS-CoV-2 and other emerging and reemerging deleterious microbiome.

The Cryptosporidium parasite with the ensuing infection of cryptosporidiosis continues unabated to constitute both environmental and public health problems in the category of emerging and reemerging diseases globally ^{35, 36}. The correlates of protective immunity and the parasitosis of the Cryptosporidium spp in both humans and animals have ostensibly confounded policy makers and researchers alike; and its prevention has involved configuring disparate or converging modes of research and policies which may have impacted, and continue to impact on geopolitics and gain-of-function issues not yet unravelled in the public domain. These tendencies are invariably manifest in cystoisosporiasis, erstwhile referred to as isosporiasis ³⁷. Globally, especially in tropical and sub-tropical ambients, the infection due to the etiologic agent, Cystoisospora belli, C. belli is common in immunocompromised persons, such as HIV-infected/AIDS patients. Cystoisosporiasis, HIV/AIDS and SARS-CoV-2 patients exhibit clinicopathological correlates pertinent to elucidate associated comorbidities and mechanisms of these disorders. Geopolitics and gain-of-function tinkering are liable to obfuscate or mask the contracting and dissemination of these diseases resulting in gross neglect of the disparate pathological influences and manifestations among vulnerable populations ³⁷. Cystoisoporiasis and several other protozoal infestations and infections, such as microsporidiosis exclusively or in comorbidity with AIDS ³⁸ are emerging and reemerging infectious diseases ¹ prevalent in low- and middle-income countries, LMICs than in high income countries.

Amongst other protozoal infections, cystoisosporiasis patients may not be more susceptible to SARS-CoV-2/COVID-19 but the probable geopolitics and gain-of-function trajectories with resultant variants pose dimensions of concern. The epidemiology and clinicopathological features of C. belli are significant for routine surveillance of the parasite in immunosuppressed patients ³⁷ for sustainable geopolitics and gain-of-function of concern as well as related anthropogenic interventions in gain-of-function research. Thus, in the ocular apparatus, SARS-CoV-2, otherwise alluded to as the coronavirus 2019 or COVID-19 has precipitated health repercursions of perturbing unprecedented magnitude or dimensions ^{39, 40} with deterioration of the ophthalmic system. It has caused susceptible individuals suffering from Acanthamoebic keratitis to seek cogent healthcare due to increased risk of COVID-19 infections via wearing of contact lenses ⁴¹. There are stringent efforts to prioritize community capacity in the surveillance and curbing of Acanthamoeba keratitis in the environ ⁴² to avoid severe ophthalmic diseases, such as anterior uveitis and conjuctivitis as well as the attendant consequences of geopolitical and gain-of-function issues.

The alleviation or eradication of local and global poverty as well as hunger ⁴³ with adequate health provisions, sustainable development and environment is a daunting task in the face of epidemics and pandemics of emerging and reemerging infectious diseases as depicted, for intance, in the scourges of the swine flu, HIV/AIDS, Ebola virus, SARS-CoV-2 or COVID-19. This is more so as we take into cognizance the UN's 17 Goals in the face of constricted resources and bourgeoning human populations inhabiting Planet Earth. With current abject poverty and hunger amongst vulnerable populations in tropical and sub-tropical Africa, Asia including Latin America in contrast to ostensibly resource-endowed North America and Europe, there are greater extant socioeconomic and healthcare deprivations and diminished wealth acquisition and resource control in the COVID-19 pandemic ^{29, 30}. The SARS-CoV-2 or COVID-19 variants have configured or undergone gain-of-function to expose local and universal geopolitics with resultant excruciating hunger ²². Indubitably, the COVID-19 pandemic with other emerging and reemerging, and non-comparatively salient infectious diseases have exposed the non-pragmatic preparedness, conscience and justice in the imposed geopolitics of local and global institutions driven by inter alia the disruption, and dimunitive capacity of small- and medium-sized enterprises. It is pertinent to predict the impact and resurgence of epidemics and pandemics of infectious diseases and their variants of concern in order to rescue the human population and businesses from extreme dissipation.
