The long-term impact of the Covid-19 pandemic on tuberculosis care and infection control measures in anti-retroviral therapy (ART) clinics in low- and middle-income countries
BACKGROUND: The COVID-19 pandemic challenged healthcare systems, particularly in settings with high infectious disease burden. We examined the postpandemic long-term impacts of COVID-19 on tuberculosis (TB) services at anti-retroviral therapy (ART) clinics in lower-income countries. METHODS: Using standardised online questionnaires, we conducted a cross-sectional site survey among ART clinics providing TB services in Africa and Asia from July to …
Community-based antiretroviral therapy (ART) delivery for female sex workers in Tanzania
To increase linkage to and retention in antiretroviral therapy (ART) care, we piloted a community-based, ART service delivery intervention for female sex workers (FSWs). At baseline, we recruited and collected data from 617 FSWs (intervention: 309; comparison: 308) who were HIV positive and not on ART. This paper presents (1) the description of the intervention model, and (2) key descriptive and bivariate-level findings of the baseline FSW cohort…
Prevalence,awareness and factors associated with hypertension in North West Tanzania
BACKGROUND: Hypertension is a public health problem, and yet few people are aware of it and even fewer access effective treatment. With the ongoing demographic transition in many parts of Sub-Saharan Africa, people are changing from rural, manual work to urban lifestyles, hence the risk of hypertension increases. OBJECTIVE: This study aimed at determining the prevalence, awareness and risk factors associated with hypertension in North West Tanzan…
Challenges with routine data sources for PMTCT programme monitoring in East Africa
Routinely collected clinic data have the potential to provide much needed information on the uptake of services to prevent mother-to-child transmission (PMTCT) of HIV, and to measure HIV prevalence in pregnant women. This article describes the methodological challenges associated with using such data, based on the experiences of researchers and programme implementers in Tanzania and drawing from other examples from East Africa. PMTCT data are rou…

INTRODUCTION: Spectrum epidemiological models are used by UNAIDS to provide global, regional and national HIV estimates and projections, which are then used for evidence-based health planning for HIV services. However, there are no validations of the Spectrum model against empirical serological and mortality data from populations in sub-Saharan Africa. METHODS: Serologic, demographic and verbal autopsy data have been regularly collected among ove…
Using HIV-attributable mortality to assess the impact of antiretroviral therapy on adult mortality in rural Tanzania
BACKGROUND: The Tanzanian national HIV care and treatment programme has provided free antiretroviral therapy (ART) to HIV-positive persons since 2004. ART has been available to participants of the Kisesa open cohort study since 2005, but data to 2007 showed a slow uptake of ART and a modest impact on mortality. Additional data from the 2010 HIV serological survey provide an opportunity to update the estimated impact of ART in this setting. METHOD…
How have ART treatment programmes changed the patterns of excess mortality in people living with HIV? Estimates from four countries in East and Southern Africa
BACKGROUND: Substantial falls in the mortality of people living with HIV (PLWH) have been observed since the introduction of antiretroviral therapy (ART) in sub-Saharan Africa. However, access and uptake of ART have been variable in many countries. We report the excess deaths observed in PLWH before and after the introduction of ART. We use data from five longitudinal studies in Malawi, South Africa, Tanzania, and Uganda, members of the network f…
InterVA-4 as a public health tool for measuring HIV/Aids mortality
BACKGROUND: Reliable population-based data on HIV infection and AIDS mortality in sub-Saharan Africa are scanty, even though that is the region where most of the world's AIDS deaths occur. There is therefore a great need for reliable and valid public health tools for assessing AIDS mortality. OBJECTIVE: The aim of this article is to validate the InterVA-4 verbal autopsy (VA) interpretative model within African populations where HIV sero-status is…
