A context-responsive health systems intervention improves the uptake of early infant HIV diagnosis
Health system challenges limit uptake of early infant diagnosis of HIV (EID). Context-appropriate strategies are required to achieve global 95% six-week testing target. We evaluated a co-designed context-appropriate enhanced health system (EEHS) intervention to strengthen client identification, appointment booking systems, leadership, and facility-based training to improve enrolment of Infants Exposed to HIV (IEH) in HIV care and testing at six w…
Developing an intervention to improve early infant HIV diagnosis service uptake among postpartum women in Malawi’s primary healthcare using a co-designing approach with stakeholders
Low health service use by women and infants after birth limits early infant HIV diagnosis (EID). From August 2021 to December 2022, we collaborated with 44 healthcare workers (HCW), service users, and non-governmental organisation stakeholders from seven public facilities and five non-governmental organisations in Blantyre, building on a previous study. We analysed context-specific problems in EID services and co-designed a context-appropriate en…
Exploring gender stereotypes and norms among peri-urban very young adolescents in Zimbabwe using participatory and qualitative approaches
Gender stereotypes and norms shape very young adolescents’ (VYAs, 10–14 years old) behaviours, including in relation to sexual and reproductive health (SRH). This formative study sought to determine and prioritise the stereotypes and norms to be targeted as part of work to co-develop a gender-transformative intervention for VYAs in Zimbabwe to promote positive masculinities and SRH. In 2023, we collected data from VYAs, using participatory worksh…
Twenty years of herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries
INTRODUCTION: Low-income and middle-income countries (LMICs) have a high burden of herpes simplex virus type 2 (HSV-2) infection, which has been strongly associated with HIV. In 2001, the WHO hosted a workshop to set research priorities for HSV-2 in LMICs. Periodic re-evaluation of research priorities is essential to ensure effective allocation of resources. This study describes the progress made between 2000 and 2020 in addressing the priorities…
Years of herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries
INTRODUCTION: Reviewing and updating research priorities is essential to assess progress and to ensure optimal allocation of financial and human resources in research. In 2001, WHO held a research priority setting workshop for herpes simplex virus type 2 (HSV-2) research in low-income and middle-income countries (LMICs). This study aimed to describe progress between 2000 and 2020 in three of the five key research priority areas outlined in the wo…
Authorship reflexivity statements
Authorship of scientific publications is key currency in academic systems. It demonstrates scientific contribution and scholarship and is an important tangible output that can strongly influence career progression and access to important resources such as grant income. However, the integrity of authorship as an indicator of contribution is threatened by normalised unfair practices.
A review of authorship in herpes simplex virus type-2 (HSV-2) research conducted in low-income and middle-income countries between 2000 and 2020
INTRODUCTION: Equitable inclusion of low-income and middle-income country (LMIC) researchers and women in research authorship is a priority. A review of progress in addressing WHO-identified priorities provided an opportunity to examine the geographical and gender distribution of authorship in herpes simplex virus type-2 (HSV-2) research. METHODS: Publications addressing five areas prioritised in a WHO workshop and published between 2000 and 2020…
“Alcohol will never run out”
Heavy alcohol use amongst adolescent boys is a major public health concern in many countries. It is associated with a range of negative physical and mental health outcomes and predicts alcohol-related problems in adulthood. In Kilimanjaro Region, adolescent boys’ alcohol use is widespread, and higher than other regions in Tanzania. An understanding of causal and contextual factors that influence the use of alcohol is needed to inform the developm…
The landscape and level of alcohol policy enforcement in Tanzania
Harmful use of alcohol causes more deaths in Sub-Saharan Africa than in any other region. In Tanzania, where alcohol use disorders rates are twice the overall African average, harmful alcohol consumption is a public health concern. Given the lack of a contemporary overview of the alcohol policy landscape, we conducted a mixed-methods review of key alcohol-related policies, implementers, and initiatives in Tanzania. We conducted a desk-based revie…
Measuring alcohol use among adolescents in Africa
‘If I am on ART, my new-born baby should be put on treatment immediately’
Early infant diagnosis of HIV (EID-HIV) is key to reducing paediatric HIV mortality. Traditional approaches for diagnosing HIV in exposed infants are usually unable to optimally contribute to EID. Point-of-care testing such as Cepheid Xpert HIV-1 Qual assay-1 (XPertHIV) are available and could improve EID-HIV in resource constrained and high HIV burden contexts. We investigated the acceptability and perceived appropriateness of XpertHIV for EID-H…
Honestly, this problem has affected me a lot”
Chronic respiratory diseases have substantial social and economic impacts among people with CRD and their families in Sudan and Tanzania. Stigma is particularly strong and appears to be driven partly by association of chronic cough with infectiousness. Context-appropriate measures to address economic impacts and chronic cough stigma are urgently needed as part of interventions for chronic respiratory diseases in these sub-Saharan African contexts
An exploration of practices affecting research integrity in global health partnerships
BACKGROUND: Research integrity is central to good research practice yet it is under-researched in global health. AIM: To identify and explore factors which promote or constrain adherence to research integrity principles in global health research partnerships, specifically at a UK higher education institution (HEI) and its low-to-middle-income country (LMIC) partners. METHODS: Qualitative study using key informant interviews among researchers at a…

Committing to anti-racism reforms? Three critical building blocks for global health organizations

“I wanted evidence that my status had changed, so that is why I tested”
HIV testing among female sex workers (FSWs) is an established global health priority. HIV self-testing (HIVST) seems to have the potential to address issues of confidentiality, privacy and convenience among this key population. HIVST, however, may result in unintended consequences as its implementation unfolds in a complex sex work context characterised by unequal power relations, stigma and high HIV prevalence. We aimed to explore the experience…
The UK’s Global Health Respiratory Network
Respiratory disorders are responsible for considerable morbidity, health care utilisation, societal costs and approximately one in five deaths worldwide [1-4]. Yet, despite this substantial health and societal burden – which particularly affects the world’s poorest populations and as such is a major contributor to global health inequalities – respiratory disorders have historically not received the \npolicy priority they warrant. For example, des…
Dusty discos and dangerous desires
This paper presents villagers' assessments of young people's sexual and reproductive health vulnerability and of community-based interventions that may reduce both vulnerability and risk in rural Mwanza, Tanzania. The primary methods used were 28 group discussions and 18 in-depth interviews with representatives of various social groups in four villages. The majority of participants attributed young people's sexual and reproductive health risks to…
Rationale and design of the Mema kwa Vijana adolescent sexual and reproductive health intervention in Mwanza Region, Tanzania
Large-scale innovative, integrated, multifaceted adolescent sexual and reproductive health (ASRH) interventions are urgently needed in sub-Saharan Africa. Implementation through schools and health facilities may maximize intervention coverage and sustainability, however the impact of the use of these structures on intervention content and delivery is not well documented. This paper describes the rationale and design of a large-scale multifaceted …
