Determining the acceptability of a novel One Health vaccine for Rift Valley Fever prior to phase II/III clinical trials in Uganda.

Several vaccine candidates for Rift Valley Fever (RVF) are in development for use in humans. A promising candidate, ChAdOx1 RVF vaccine, has been developed for use in both humans and animals, and has undergone field trials in livestock in Kenya. We conducted a qualitative study to explore the acceptability of this novel One Health vaccine for Rift Valley Fever prior to phase II/III trials, in two rural Ugandan cohorts between January to June 2020. Data was obtained from 96 semi-structured interviews at Bwindi Impenetrable National Park (BINP) and Kyamulibwa, Kalungu District, in Southern Uganda. The study found that 42% of those interviewed were willing to receive a vaccine that was the same for both humans and animals. 45% of those interviewed said that they would not be willing to receive a One Health vaccine and a further 13% were unsure whether or not they would be happy to receive such a vaccine. Semi-structured interviews were conducted to explore their reasons for and against the acceptability of a novel One Health vaccine to highlight potential barriers to deployment once a vaccine candidate for RVF becomes available

Protecting great apes from disease: Compliance with measures to reduce anthroponotic disease transmission

Abstract: The emergence of infectious diseases, such as COVID‐19, impacts livelihood strategies and conservation tools reliant on human‐wildlife interactions, such as wildlife‐based tourism and research. This is particularly relevant to great ape conservation, as humans and great apes are susceptible to being infected by similar pathogens. Evidence‐based strategies are required to prevent infectious disease transmission to great apes and people involved in, or living close to, tourism sites. The development of disease‐safe recommendations and their effective operationalisation require an understanding of what affects visitor compliance. Based on an international sample of past (N = 420) and potential future visitors (N = 569) to wild great ape tourism sites in Africa, we used an online questionnaire to characterise visitors' practices, assess expectations (e.g. about proximity to great apes) and identify key factors related to potential compliance with disease mitigation measures. This was implemented adapting a framework from health literature (the Health Belief Model; HBM), particularly focused on reducing COVID‐19 transmission at an early stage of the pandemic. Visitors expressed less willingness to being vaccinated against COVID‐19 (which, at the time our survey was conducted, had only just started being administered to very high‐risk groups), wearing a facemask during trekking (although willing when viewing the apes) and quarantine after international travel before visiting great apes. Region of nationality, expectations about the visitor experience and perceived effectiveness of specific measures were important factors explaining variation in potential compliance across multiple behaviours. By gaining a better understanding of what fosters compliance with disease mitigation measures, we obtained insights that are essential for assessing feasibility, facilitating effective communication, and guiding implementation at great ape tourism sites with importance not only for COVID‐19 but also for other infectious diseases more broadly, particularly at early stages of future pandemics. While requiring adaptive management as situations evolve (e.g. vaccination becoming more widely accessible), these will contribute towards a more sustainable visitor experience that can effectively deliver positive outcomes for people and biodiversity.

Family Planning and the Millennium Development Goals

The United Nations' (UN's) eight Millennium Development Goals (MDGs) (1) are widely accepted as the primary path to alleviating poverty worldwide. This month, world leaders convene to assess progress toward these goals (2). In the countdown to the MDG 2015 deadline and amid protracted economic recession, we need the most efficient, effective, and evidence-based means to accelerate progress toward all MDGs. Challenges must be considered in concert, and solutions must provide multidimensional dividends for the world's poor, or we risk unwisely dividing limited resources and diluting their impact. As authors from diverse communities, we emphasize here the influence that investments in rights-based family planning can have on achieving the MDGs

News and Perspectives: Words matter in primatology

Postings on social media on Twitter (now X), BioAnthropology News (Facebook), and other venues, as well as recent publications in prominent journals, show that primatologists, ecologists, and other researchers are questioning the terms “Old World” and “New World” due to their colonial implications and history. The terms are offensive if they result in erasing Indigenous voices and history, ignoring the fact that Indigenous peoples were in the Americas long before European colonization. Language use is not without context, but alternative terminology is not always obvious and available. In this perspective, we share opinions expressed by an international group of primatologists who considered questions about the use of these terms, whether primatologists should adjust language use, and how to move forward. The diversity of opinions provides insight into how conventional terms used in primatological research and conservation may impact our effectiveness in these domains

Engaging Research with Policy and Action: What are the Challenges of Responding to Zoonotic Disease in Africa?

Zoonotic diseases will maintain a high level of public policy attention in the coming decades. From the spectre of a global pandemic to anxieties over agricultural change, urbanization, social inequality and threats to natural ecosystems, effectively preparing and responding to endemic and emerging diseases will require technological, institutional and social innovation. Much current discussion emphasizes the need for a ‘One Health’ approach: bridging disciplines and sectors to tackle these complex dynamics. However, as attention has increased, so too has an appreciation of the practical challenges in linking multi-disciplinary, multi-sectoral research with policy, action and impact. In this commentary paper, we reflect on these issues with particular reference to the African sub-continent. We structure the themes of our analysis on the existing literature, expert opinion and 11 interviews with leading One Health scholars and practitioners, conducted at an international symposium in 2016. We highlight a variety of challenges in research and knowledge production, in the difficult terrain of implementation and outreach, and in the politicized nature of decision-making and priority setting. We then turn our attention to a number of strategies that might help reconfigure current pathways and accepted norms of practice. These include: (i) challenging scientific expertise; (ii) strengthening national multi-sectoral coordination; (iii) building on what works; and (iv) re-framing policy narratives. We argue that bridging the research-policy-action interface in Africa, and better connecting zoonoses, ecosystems and well-being in the twenty-first century, will ultimately require greater attention to the democratization of science and public policy. This article is part of the themed issue ‘One Health for a changing world: zoonoses, ecosystems and human well-being’

Integration of medical service provision and nature conservation worldwide 1980–2022: collaborative evidence mapping of 43 projects across 22 countries

Background Biodiversity protection is fundamental to human wellbeing, and, in turn, serving human health in medically underserved areas can sometimes strengthen conservation. We aimed to collaboratively map the evidence on projects worldwide that are, or have been, providing health services with the intention of producing conservation outcomes in addition to health improvements. Methods Scoping indicated many NGO projects are never published in the academic literature. To avoid missing such interventions we asked conservation staff worldwide to contribute data online or through zoom calls. Advertising to join the collaboration was through formal networks (International Union for Conservation of Nature, Planetary Health Alliance, etc.), professional contacts, funders, and a call in The Lancet Planetary Health. Additionally, data and literature were synthesised from libraries and datasets of collaborators at Population Reference Bureau, Sussex Sustainability Research Programme, and Ecological Levers for Health. Findings Forty-three projects from 22 countries fitted inclusion criteria. Around half had not been published in the collected literature, with data only available through direct submission. Tropical wet forest was by far the most common habitat, followed by tropical dry forest, coral reefs, and tropical grasslands. The most represented region was Sub-Saharan Africa with 27 projects, followed by South-East Asia (five), South Asia (five), Oceania (two), South America (two), Central America (one), Europe (one). Projects ranged from basic health interventions bolted on to pre-existing conservation programmes to generate goodwill (e.g., vaccination rounds bordering national parks) to complex schemes jointly acting on health and biodiversity driven (and funded) by concerns for human welfare as much as conservation. Interpretation Synergistic action on biodiversity conservation and health service provision is very often effective and the approach is more widespread than literature would indicate. However, funding was usually provided on a siloed basis for either health or conservation, and this remains a barrier to wider adoption

Molecular characterisation of protist parasites in human-habituated mountain gorillas (Gorilla beringei beringei), humans and livestock, from Bwindi impenetrable National Park, Uganda

Over 60 % of human emerging infectious diseases are zoonotic, and there is growing evidence of the zooanthroponotic transmission of diseases from humans to livestock and wildlife species, with major implications for public health, economics, and conservation. Zooanthroponoses are of relevance to critically endangered species; amongst these is the mountain gorilla (Gorilla beringei beringei) of Uganda. Here, we assess the occurrence of Cryptosporidium, Cyclospora, Giardia, and Entamoeba infecting mountain gorillas in the Bwindi Impenetrable National Park (BINP), Uganda, using molecular methods. We also assess the occurrence of these parasites in humans and livestock species living in overlapping/adjacent geographical regions

Infection and exposure to vector-borne pathogens in rural dogs and their ticks, Uganda

BACKGROUND: In rural parts of Africa, dogs live in close association with humans and livestock, roam freely, and usually do not receive prophylactic measures. Thus, they are a source of infectious disease for humans and for wildlife such as protected carnivores. In 2011, an epidemiological study was carried out around three conservation areas in Uganda to detect the presence and determine the prevalence of vector-borne pathogens in rural dogs and associated ticks to evaluate the risk that these pathogens pose to humans and wildlife. METHODS: Serum samples (n = 105), blood smears (n = 43) and blood preserved on FTA cards (n = 38) and ticks (58 monospecific pools of Haemaphysalis leachi and Rhipicephalus praetextatus including 312 ticks from 52 dogs) were collected from dogs. Dog sera were tested by indirect immunofluorescence to detect the presence of antibodies against Rickettsia conorii and Ehrlichia canis. Antibodies against R. conorii were also examined by indirect enzyme immunoassay. Real time PCR for the detection of Rickettsia spp., Anaplasmataceae, Bartonella spp. and Babesia spp. was performed in DNA extracted from FTA cards and ticks. RESULTS: 99 % of the dogs were seropositive to Rickettsia spp. and 29.5 % to Ehrlichia spp. Molecular analyses revealed that 7.8 % of the blood samples were infected with Babesia rossi, and all were negative for Rickettsia spp. and Ehrlichia spp. Ticks were infected with Rickettsia sp. (18.9 %), including R. conorii and R. massiliae; Ehrlichia sp. (18.9 %), including E. chaffeensis and Anaplasma platys; and B. rossi (1.7 %). Bartonella spp. was not detected in any of the blood or tick samples. CONCLUSIONS: This study confirms the presence of previously undetected vector-borne pathogens of humans and animals in East Africa. We recommend that dog owners in rural Uganda be advised to protect their animals against ectoparasites to prevent the transmission of pathogens to humans and wildlife
