  • Heterogeneity in Mycobacterium tuberculosis immunoreactivity in young children in Blantyre, Malawi

    Open AccessHannah M Rickman, Mphatso D Phiri et al.ARTICLEPLOS Global Public Health2026

    As tuberculosis (TB) incidence declines, transmission becomes increasingly concentrated in vulnerable populations and neighbourhoods. There is an urgent need for affordable surveillance strategies to monitor trends, identify high-risk groups and target interventions. TB disease prevalence surveys are no longer cost-effective in monitoring epidemiological trends as countries target TB elimination, while passive surveillance methodologies such as c…

  • Optimizing peer-led health interventions

    Open AccessMadalo Mukoka, Alison Price et al.ARTICLEPLOS Global Public Health2026

    Social network interventions (SNIs) can leverage influential individuals within personal networks to amplify health behavior adoption and intervention diffusion. While SNIs are potentially effective in enhancing uptake of HIV prevention and other interventions, identifying optimal peer leaders remains challenging. This study assessed how social network-based approaches can improve peer leader identification compared to non-structural approaches (…

  • The influence of social networks in adoption of integrated health interventions

    Open AccessMadalo Mukoka, Owen Mhango et al.ARTICLEPLOS Global Public Health2025

    Introduction Social networks play a vital role in influencing individual and collective health behaviors and facilitating the diffusion of health interventions. Fishing communities in sub-Saharan Africa face socio-cultural and occupational challenges such as low literacy rates and high mobility. However, their high social cohesion creates a unique social environment for spreading health interventions. We explored the role of social relationships …

  • Distribution and transmission of M. tuberculosis in a high-HIV prevalence city in Malawi

    Open AccessMelanie H Chitwood, Elizabeth L Corbett et al.ARTICLEPLOS Global Public Health2025

    Delays in identifying and treating individuals with infectious tuberculosis (TB) contribute to poor health outcomes and allow ongoing community transmission of M. tuberculosis ( Mtb ). Current recommendations for screening for tuberculosis specify community characteristics (e.g., areas with high local tuberculosis prevalence) that can be used to target screening within the general population. However, areas of higher tuberculosis burden are not n…

  • Acceptability of self-sampling for high-risk HPV DNA testing for primary cervical cancer screening among women in Thyolo, Malawi

    Open AccessHussein H Twabi, Wakumanya Sibande et al.ARTICLEPLOS Global Public Health2025

    Despite the roll-out of cervical cancer screening within routine health facilities, uptake of cervical cancer screening in Malawi remains low due to factors such as privacy concerns, stigma, and distance to health facility. Self-sampling for human papillomavirus (HPV) testing offers a viable alternative to provider-delivered sampling, resolving issues with accessibility and privacy related barriers. However, there is limited understanding of the …

  • The Acceptability of a Real-Time Medication Monitoring-Based Digital Adherence Tool Among Young People Living with HIV in Malawi

    Open AccessTakondwa Msosa, Felix Phuka et al.ARTICLEAIDS and Behavior2025

    Adherence to antiretroviral therapy (ART) is required for young people living with HIV (YPLHIV, 15-24 years) to achieve viral suppression, prevent transmission, and reduce HIV-related morbidity and mortality. Real time medication monitoring based digital adherence tools (RTMM-DATs) - a combination of RTMMs (smart pillboxes), customised adherence feedback, SMS reminders, and optional alarms - may be used to provide promising interventions to impro…

  • Prevalence and Determinants of Viral Suppression in Young People Living with HIV on Antiretroviral Therapy in Southern Africa

    Open AccessTakondwa Msosa, Alinune N Kabaghe et al.ARTICLEAIDS and Behavior2025

    Young People Living with HIV (YPLHIV, 15-24 years) are an important demographic of Persons Living with HIV (PLHIV) globally and in Southern Africa. However, YPLHIV experience poor outcomes across the HIV diagnostic and treatment cascade due to multiple factors. We estimated the prevalence and determinants of HIV viral suppression in YPLHIV on antiretroviral therapy (ART) in selected Southern African countries. We used publicly available data from…

  • Impact of active case-finding for tuberculosis on case-notifications in Blantyre, Malawi

    Open AccessHelena R A Feasey, McEwen Khundi et al.ARTICLEPLOS Global Public Health2023

    Active case-finding (ACF) for tuberculosis can help find the “missing millions” with undiagnosed tuberculosis. In a cluster-randomised trial, we investigated impact of ACF on case-notifications in Blantyre, Malawi, where ACF has been intensively implemented following 2014 estimates of ~1,000 per 100,000 adults with undiagnosed TB. Following a pre-intervention prevalence survey (May 2019 to March 2020), constrained randomisation allocated neighbou…

  • Interventions to reduce deaths in people living with HIV admitted to hospital in low- and middle-income countries

    Open AccessRachael M Burke, Hussein H Twabi et al.ARTICLEPLOS Global Public Health2023

    People living with HIV (PLHIV) admitted to hospital have a high risk of death. We systematically appraised evidence for interventions to reduce mortality among hospitalised PLHIV in low- and middle-income countries (LMICs). Using a broad search strategy with terms for HIV, hospitals, and clinical trials, we searched for reports published between 1 Jan 2003 and 23 August 2021. Studies of interventions among adult HIV positive inpatients in LMICs w…

  • Prevalence of bacteriologically-confirmed pulmonary tuberculosis in urban Blantyre, Malawi 2019–20

    Open AccessHelena R A Feasey, McEwen Khundi et al.ARTICLEPLOS Global Public Health2023

    Recent evidence shows rapidly changing tuberculosis (TB) epidemiology in Southern and Eastern Africa, with need for subdistrict prevalence estimates to guide targeted interventions. We conducted a pulmonary TB prevalence survey to estimate current TB burden in Blantyre city, Malawi. From May 2019 to March 2020, 115 households in middle/high-density residential Blantyre, were randomly-selected from each of 72 clusters. Consenting eligible particip…

  • Do community-based active case-finding interventions have indirect impacts on wider TB case detection and determinants of subsequent TB testing behaviour? A systematic review

    Open AccessHelena R A Feasey, Rachael M Burke et al.ARTICLEPLOS Global Public Health2021

    Community-based active case-finding (ACF) may have important impacts on routine TB case-detection and subsequent patient-initiated diagnosis pathways, contributing “indirectly” to infectious diseases prevention and care. We investigated the impact of ACF beyond directly diagnosed patients for TB, using routine case-notification rate (CNR) ratios as a measure of indirect effect. We systematically searched for publications 01-Jan-1980 to 13-Apr-202…

  • Discordance, Disclosure and Normative Gender Roles

    Open AccessMoses Kumwenda, Moses Kelly Kumwenda et al.ARTICLEAIDS and Behavior2018

    A community-based HIV self-testing study in Blantyre, Malawi demonstrated that not all individuals living in couples tested with their partner. We describe factors dissuading individuals in couples from self-testing with their partner. Data were drawn from qualitative study exploring consequences of HIV self-testing within couples. In-depth interviews were conducted with 33 individuals living in couples who tested alone. Participants expressed fe…
