  • Consolidation of a genomic epidemiological surveillance network for tuberculosis (Reviget) in northern and northeastern Brazil

    Open AccessEmilyn Costa Conceição, Karla Valéria Batista Lima et al.ARTICLEFrontiers in Public Health2025

    Globally, tuberculosis (TB) remains a top cause of death from infectious diseases, with an estimated 1.5 million deaths annually. Given its substantial social and economic burden, TB is a priority in the United Nations 2030 Agenda for Sustainable Development. The WHO’s End TB Strategy emphasizes research, innovation, and the rapid implementation of new technologies, such as whole-genome sequencing (WGS), which are pivotal for precision health app…

  • Importance of outbreak response research in bridging knowledge gaps on emerging infectious diseases

    Open AccessRobert F Breiman, Eric Osoro et al.ARTICLEBMJ Global Health2025

    An important outcome of the devastating 2014 West African Ebola virus disease outbreak and the 2020 COVID-19 pandemic has been the growing promotion of conducting research during outbreaks of emerging infectious diseases (EIDs) as a valuable and acceptable process of acquiring knowledge to enhance our ability to better prevent and control these diseases in the future. Recognising the unique opportunity during outbreaks to leverage increases in ca…

  • “The Covid-19 pandemic in BRICS

    Open AccessStephanie van Wyk, Monika Moir et al.ARTICLEPLOS Global Public Health2024

    Brazil, Russia, India, China, and South Africa (BRICS) are a group of developing countries with shared economic, healthcare, and scientific interests. These countries navigate multiple syndemics, and the COVID-19 pandemic placed severe strain on already burdened BRICS’ healthcare systems, hampering effective pandemic interventions. Genomic surveillance and molecular epidemiology remain indispensable tools for facilitating informed pandemic interv…

  • Genomic epidemiology of Sars-CoV-2 during the first four waves in Mozambique

    Open AccessNalia Ismael, Stephanie van Wyk et al.ARTICLEPLOS Global Public Health2023

    Mozambique reported the first case of coronavirus disease 2019 (COVID-19) in March 2020 and it has since spread to all provinces in the country. To investigate the introductions and spread of SARS-CoV-2 in Mozambique, 1 142 whole genome sequences sampled within Mozambique were phylogenetically analyzed against a globally representative set, reflecting the first 25 months of the epidemic. The epidemic in the country was marked by four waves of inf…

  • The role of high-risk geographies in the perpetuation of the HIV epidemic in rural South Africa

    Open AccessDiego F Cuadros, Tulio de Oliveira et al.ARTICLEPLOS Global Public Health2022

    In this study, we hypothesize that HIV geographical clusters (geospatial areas with significantly higher numbers of HIV positive individuals) can behave as the highly connected nodes in the transmission network. Using data come from one of the most comprehensive demographic surveillance systems in Africa, we found that more than 70% of the HIV transmission links identified were directly connected to an HIV geographical cluster located in a peri-u…

  • The geography and inter-community configuration of new sexual partnership formation in a rural South African population over fourteen years (2003–2016)

    Open AccessHae‐young Kim, Diego F Cuadros et al.ARTICLEPLOS Global Public Health2022

    Understanding spatial configuration of sexual network structure is critical for effective use of HIV preventative interventions in a community. However, this has never been described at the population level for any setting in sub-Saharan Africa. We constructed the comprehensive geospatial sexual network among new heterosexual partnerships in rural KwaZulu-Natal, South Africa. In the Africa Health Research Institute (AHRI)’s population-based surve…

  • Using the Emanuel Framework to Explore the Ethical Issues Raised in a Participatory Visual Research Project in Rural South Africa

    Open AccessAstrid Treffry-Goatley, R Moletsane et al.ARTICLEJournal of Empirical Research on…2021References: 9

    Participatory visual research can offer critical insight into the experiences of those most affected by health issues. As these methods are increasingly used to research sensitive topics, there is a need for a clear ethical framework to guide best practice on the part of researchers and research ethics committees. Here we reflect on a project where we used digital storytelling as a participatory visual methodology to explore HIV treatment adheren…

  • Ethical issues associated with HIV phylogenetics in HIV transmission dynamics research

    Open AccessFarirai Mutenherwa, Douglas Wassenaar et al.ARTICLEDeveloping World Bioethics2019

    The reduced costs of DNA sequencing and the use of such data for HIV ‐1 clinical management and phylogenetic analysis have led to a massive increase of HIV ‐1 sequences in the last few years. Phylogenetic analysis has shed light on the origin, spread and characteristics of HIV ‐1 epidemics and outbreaks. Phylogenetic analysis is now also being used to advance our knowledge of the drivers of HIV ‐1 transmission in order to design effective interve…

  • Experts’ Perspectives on Key Ethical Issues Associated With HIV Phylogenetics as Applied in HIV Transmission Dynamics Research

    Open AccessFarirai Mutenherwa, Douglas Wassenaar et al.ARTICLEJournal of Empirical Research on…2018Cited by: 1References: 7

    The use of phylogenetics in HIV molecular epidemiology has considerably increased our ability to understand the origin, spread, and characteristics of HIV epidemics. Despite its potential to advance knowledge on HIV transmission dynamics, the ethical issues associated with HIV molecular epidemiology have received minimal attention. In-depth interviews were conducted with scientists from diverse backgrounds to explore their perspectives on ethical…

  • Community engagement with HIV drug adherence in rural South Africa

    Open AccessAstrid Treffry-Goatley, Richard Lessells et al.ARTICLEMedical Humanities2018Cited by: 1References: 1

    Digital storytelling (DST) is an emerging participatory visual method which combines storytelling traditions with computer and video production technology. In this project, at the heart of the HIV epidemic in KwaZulu-Natal, South Africa, we used DST to create a culturally grounded community engagement intervention. Our aim was to use narratives of people living with HIV on antiretroviral therapy (ART) to stimulate dialogue among the wider communi…

  • High percentage of undiagnosed HIV cases within a hyperendemic South African community

    Alain Vandormael, Tulio de Oliveira et al.ARTICLEJournal of Epidemiology and…2018References: 28

    BACKGROUND: Undiagnosed HIV infections could undermine efforts to reverse the global AIDS epidemic by 2030. In this study, we estimated the percentage of HIV-positive persons who remain undiagnosed within a hyperendemic South African community. METHODS: The data come from a population-based surveillance system located in the Umkhanyakude district of the northern KwaZulu-Natal province, South Africa. We annually tested 38 661 adults for HIV betwee…
