  • “Any time because I am ready”

    Open AccessWinfrida Onesmo Akyoo, Idda Hubert Mosha et al.ARTICLEFrontiers in Public Health2025

    Background: Human immunodeficiency virus (HIV) is still a major global public health problem. Sub-Saharan Africa remains the most severely affected, accounting for 69% of the people living with HIV worldwide. Currently, Pre-Exposure Prophylaxis [PrEP] pills are offered but are highly affected by non-adherence. Long-acting injectable PrEP has the potential to improve adherence. Objective: This study aimed to explore awareness and willingness to us…

  • “If I wasn’t a pastor, I would be telling them about condoms, contraceptives and PrEP”—conflicts, dilemmas and credibility

    Open AccessHannah Goymann, Astrid Berner-Rodoreda et al.ARTICLEBMJ Global Health2025

    BACKGROUND: Religious leaders (RLs) form an influential group in Eswatini. This study explores their understanding and acceptance of pre-exposure prophylaxis (PrEP), with a view to improve PrEP service delivery for those who would benefit from PrEP the most. METHODS: We conducted online and in-person in-depth interviews with (n=26) purposefully selected RLs (n=12 female and n=14 male) from Eswatini. Data were managed using NVivo V.12 and coded in…

  • Formalized peer referral to HIV pre-exposure prophylaxis supported with self-testing

    Open AccessMaureen McGowan, Njeri Wairimu et al.ARTICLEFrontiers in Public Health2024

    Background: The uptake of daily oral HIV pre-exposure prophylaxis (PrEP)-a highly effective intervention-remains low among African adolescent girls and young women (AGYW) who could benefit. AGYW who initiate PrEP often do so through informal peer referral, which may be enhanced with formalized peer referral and peer-delivered HIV self-testing (HIVST). To understand the feasibility of this PrEP referral model among AGYW, we conducted a pilot study…

  • Transferable data exclusivity vouchers are not the solution to the antimicrobial drug development crisis

    Open AccessAstrid Berner-Rodoreda, Frank Cobelens et al.ARTICLEBMJ Global Health2024

    Access to pharmaceutical products worsened during the COVID-19 pandemic when key developers of active pharmaceutical ingredients and medicinal products prioritised their national markets. These challenges led to a stronger commitment by the European Union (EU) to become more autonomous in developing and providing access to pharmaceutical products for its population.1 In April 2023, the European Commission (EC) proposed a reform of the EU pharma r…

  • Age-disparate and intergenerational sex partnerships and HIV

    Open AccessDomonique M Reed, Domonique Reed et al.ARTICLEBMC Public Health2024

    In this Malawi general population survey, age-mixing partnerships were associated with increased odds of HIV among AGYW. These findings highlight inequitable gender norms as a potential focus for HIV prevention and could inform interventions targeting structural, cultural, and social constraints of this key group

  • From disgusting and complicated to simple and brilliant

    Open AccessFreda Röhr, Ferdinand Uellner et al.ARTICLEFrontiers in Public Health2023

    Background Despite the important role of testing as a measure against the COVID-19 pandemic, user perspectives on SARS-CoV-2 tests remain scarce, inhibiting an improvement of testing approaches. As the world enters the third year of the pandemic, more nuanced perspectives of testing, and opportunities to expand testing in a feasible and affordable manner merit consideration. Methods Conducted amid the second pandemic wave (late 2020–early 2021) d…

  • Knowledge, attitudes, and practices toward Covid-19 prevention in Yemen

    Open AccessOla El Hajj Hassan, Ahmed Asa’ad Al-Aghbari et al.ARTICLEFrontiers in Public Health2023

    Background Pandemics, especially in fragile war-torn countries like Yemen, challenge their already strained health systems. Community adherence to pandemic prevention measures is necessary to curb the severity and spread of emerging pandemics – which is influenced by factors, such as people’s knowledge and attitudes toward the pandemic. No studies in Aden have been published on the communities’ knowledge, attitudes, and practices (KAP) toward COV…

The objective of this study was to assess the knowledge of health workers with regard to GBV and related management guidelines and implementation. (2) Methods: The study employed a descriptive, sequential mix-method study, beginning with the quantitative par…

  • We Should Not Be Quiet but We Should Talk

    Open AccessHannah Goymann, Mxolisi Mavuso et al.ARTICLEQualitative Health Research2023References: 48

    Community leaders play an important role in the acceptance of public health services, but little is known about their willingness to facilitate HIV pre-exposure prophylaxis (PrEP) roll-out in Eswatini. We conducted in-depth interviews ( n = 25) with purposefully selected male and female community leaders in Eswatini. We analysed our data inductively using a thematic analysis approach. Community leaders feel they are important communicators of cul…

  • Assessing young Kenyan women's willingness to engage in a peer-delivered HIV self-testing and referral model for PrEP initiation

    Open AccessMaureen McGowan, Edinah Casmir et al.ARTICLEFrontiers in Public Health2022

    Background: Pre-exposure prophylaxis (PrEP) is highly effective for HIV prevention, but uptake remains low, especially among adolescent girls and young women (AGYW) in Kenya. A model in which trained AGYW using PrEP deliver HIV self-tests to their close friends and refer them to PrEP may help increase PrEP uptake in this population. To understand AGYW's potential willingness to engage in such a model, we conducted a qualitative formative study in…

  • Clinical and Epidemiological Presentation of Covid-19 among Children in Conflict Setting

    Open AccessMaureen Dar Iang, Ola El Hajj Hassan et al.ARTICLEChildren2022

  • Increasing health system synergies in low-income settings

    Open AccessMartin Rudasingwa, Andreas Jahn et al.ARTICLEGlobal Public Health2022

    Building synergies is seen as an effective strategy to address and decrease existing fragmentation in health systems of low-and middle-income countries (LMICs). To that end, different programmes, such as the Sector Wide Approach, have been adopted to increase health system synergies. Despite these efforts, fragmentation remains an enduring problem, hampering health system performance in LMICs. This study is part of the Lancet Commission on synerg…

  • Field evaluation of specificity and sensitivity of a standard Sars-CoV-2 antigen rapid diagnostic test

    Open AccessAlhassan Abdul-Mumin, Abdulai Abubakari et al.ARTICLEPLOS Global Public Health2021

    The testing capacity for SARS-CoV-2 in Africa is rather limited. Antigen detection rapid diagnostic tests (Ag-RDTs) are a cheap and rapid alternative to reverse transcriptase-polymerase chain reaction (RT-PCR) tests, but there is little data about their performance under real life conditions in tropical countries. The objective of this study is to evaluate the performance of a standard Ag-RDT in a population of a major hospital in northern Ghana.…

  • Protocol for a Case-Control Study to Investigate the Association of Pellagra With Isoniazid Exposure During Tuberculosis Preventive Treatment Scale-Up in Malawi

    Open AccessScott A Nabity, Kelvin Mponda et al.ARTICLEFrontiers in Public Health2020

    Background: Pellagra is caused by niacin (vitamin B3) deficiency and manifested by a distinctive dermatitis. Isoniazid is critical for treating tuberculosis globally and is a component of most regimens to prevent tuberculosis. Isoniazid may contribute to pellagra by disrupting intracellular niacin synthesis. In 2017, Malawian clinicians recognized a high incidence of pellagra-like rashes after scale-up of isoniazid preventive treatment (IPT) to p…
