  • Perceived gender equitable norms and previous tuberculosis testing in Malawi

    Open AccessElizabeth Di Giacomo, Emily S Nightingale et al.ARTICLEPLOS Global Public Health2026

    Substantial evidence demonstrates that men have a higher prevalence of tuberculosis (TB) and decreased use of TB services compared to women. Gender roles and norms contribute to these disparities by influencing social and structural determinants, as well as individual behaviours. In this analysis, we investigated attitudes towards gender equitable norms and TB testing behaviours amongst Malawian men and women participating in a prevalence survey …

  • 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…

  • 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…

  • 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…
