Introduction: Recent decades have seen a growth in multisectoral and transdisciplinary approaches to improving global health, particularly across human, animal and environmental health-related sciences that advocate for participatory, systems-based perspectives to understanding and promoting health and well-being in the context of social and ecological interactions. For several issues, including human health, animal health and food security, researchers have highlighted the need for transdisciplinary One Health approaches to assess the sustainability of interventions. To understand the current thinking and conceptualisation of sustainability across One Health disciplines, we present a protocol paper for an umbrella systematic review study planned in 2024.

The integration of human, animal, and environmental health in the One Health framework is crucial for tackling complex health and environmental issues. Governance structures in One Health initiatives are essential for coordinating efforts, fostering partnerships, and establishing effective policy frameworks. This systematic review, registered with PROSPERO, aims to evaluate governance architectures in One Health initiatives.

Background: National Bridging Workshops (NBW) are a tool for reviewing collaboration gaps between line ministries relevant to the One Health framework.

Methods: The NBW for Somalia was held on November 11-13, 2023 in Nairobi, Kenya with support from WHO and WOAH. Participants included representatives from the Somali government both national and sub-national (including Ministry of Health; Ministry of Livestock, Forestry and Range; Ministry of Agriculture and Irrigation; and Ministry of Environment and Climate Change).

Changes in the epidemiology and ecology of H5N1 highly pathogenic avian influenza are devastating wild bird and poultry populations, farms and communities, and wild mammals worldwide. Having originated in farmed poultry, H5N1 viruses are now spread globally by wild birds, with transmission to many mammal and avian species, resulting in 2024 in transmission among dairy cattle with associated human cases. These ecological changes pose challenges to mitigating the impacts of H5N1 highly pathogenic avian influenza on wildlife, ecosystems, domestic animals, food security, and humans.

Introduction: Effective and safe vaccines against COVID-19 are essential to achieve global control of the coronavirus (SARS-CoV-2). Using faith centres may offer a promising route for promoting higher vaccine uptake from certain minority ethnic groups known to be more likely to be vaccine hesitant.

Methods: This cross-sectional study explored attendees' perceptions, experiences of being offered, and receiving COVID-19 vaccination in a local mosque in Woking, Surrey, UK.

The COVID-19 pandemic exposed vulnerabilities in many health systems worldwide with profound implications for health and society. The public health challenges experienced during the pandemic have highlighted the importance of resilient health systems, that can adapt and transform to meet the population's evolving health needs. Essential public health functions (EPHFs) offer a holistic, integrated and sustainable approach to public health by contributing to achieving several health priorities and goals.

Introduction: The burden of chronic viral hepatitis (CVH) in the UK Nepali population is unknown. We aimed to determine knowledge of liver disease (LD) and prevalence of CVH in this community.

Methods: This was a mixed method (qualitative and quantitative) study guided by a multidisciplinary stakeholder group.

Background: The human population of Somalia is vulnerable to zoonoses due to a high reliance on animal husbandry. This disease risk is exacerbated by relatively low income (poverty) and weak state capacity for health service delivery in the country as well as climate extremes and geopolitical instability in the region. To address this threat to public health efficiently and effectively, it is essential that all sectors have a common understanding of the priority zoonotic diseases of greatest concern to the country.

The health of humans, domestic and wild animals, plants, and the environment are inter-dependent. Global anthropogenic change is a key driver of disease emergence and spread and leads to biodiversity loss and ecosystem function degradation, which are themselves drivers of disease emergence. Pathogen spill-over events and subsequent disease outbreaks, including pandemics, in humans, animals and plants may arise when factors driving disease emergence and spread converge.

Article Synopsis
  • Culturally tailored interventions are essential to improve COVID-19 health practices within Black and South Asian communities in the UK, focusing on a short film and electronic leaflet as tools for change.
  • The study utilizes mixed methods, including focus groups and questionnaires, to assess how well the intervention's messages are understood and its impact on participants' intentions to adopt COVID-19 protective behaviors.
  • Ethical approval was obtained, and findings will be shared in academic journals and through health organizations to ensure messages are appropriate and effective for the target communities.

Objectives: The global reported cumulative case-fatality ratios (rCFRs) and excess mortality rates of the 20 countries with the highest coronavirus disease 2019 (COVID-19) vaccination rates, the rest of the world and Sub-Saharan Africa (SSA) were compared before and after the commencement of vaccination programmes.

Methods: A time series model was used to understand the trend of rCFR over time, and a generalized linear mixed model was used to understand the effect of vaccination on rCFR.

Results: By 31 December 2022, an average of 260.

The apparent failure of global health security to prevent or prepare for the COVID-19 pandemic has highlighted the need for closer cooperation between human, animal (domestic and wildlife), and environmental health sectors. However, the many institutions, processes, regulatory frameworks, and legal instruments with direct and indirect roles in the global governance of One Health have led to a fragmented, global, multilateral health security architecture. We explore four challenges: first, the sectoral, professional, and institutional silos and tensions existing between human, animal, and environmental health; second, the challenge that the international legal system, state sovereignty, and existing legal instruments pose for the governance of One Health; third, the power dynamics and asymmetry in power between countries represented in multilateral institutions and their impact on priority setting; and finally, the current financing mechanisms that predominantly focus on response to crises, and the chronic underinvestment for epidemic and emergency prevention, mitigation, and preparedness activities.

Article Synopsis
  • The COVID-19 pandemic has revealed weaknesses in current public health emergency preparedness frameworks, which inadequately address various social, economic, and ecological factors.
  • The One Health approach, which examines connections among humans, animals, and ecosystems, offers a useful perspective for improving these assessment frameworks.
  • A radical increase in ambition is necessary for health security assessments to encompass complex systems and prioritize core One Health principles, while also evaluating interventions based on their holistic benefits and trade-offs.

In this Series paper, we review the contributions of One Health approaches (ie, at the human-animal-environment interface) to improve global health security across a range of health hazards and we summarise contemporary evidence of incremental benefits of a One Health approach. We assessed how One Health approaches were reported to the Food and Agricultural Organization of the UN, the World Organisation for Animal Health (WOAH, formerly OIE), and WHO, within the monitoring and assessment frameworks, including WHO International Health Regulations (2005) and WOAH Performance of Veterinary Services. We reviewed One Health theoretical foundations, methods, and case studies.
