Enhancing PrEP persistence
Introduction Globally, women who engage in sex work (WESW) have a 21-fold greater risk of HIV acquisition than the general population, yet persistence on HIV pre-exposure prophylaxis (PrEP) remains low. The role of stigma and discrimination in early PrEP discontinuation is poorly understood. We examined the association between stigma, discrimination and early PrEP discontinuation among WESW in Lusaka, Zambia. Methods Using a prospective cohort de…
The perceived impacts of United States foreign development assistance reductions on health system building blocks at healthcare facilities in Zambia
The rapid reduction in foreign development assistance from the United States and other countries in 2025 has disrupted essential global health programming. Countries that previously received development assistance, such as Zambia, may experience weakening of health system capacity due to program cancellations. This study aimed to describe the perceived impacts of USAID program defunding on healthcare delivery in Zambia. We conducted a cross-secti…
Applying human-centered design to adapt a multifaceted implementation strategy for integrating HIV and NCD services in Lusaka, Zambia
There has been limited research reporting approaches used in the adaptation of implementation strategies for integrating HIV and NCD services that involve healthcare providers in low- and middle-income country (LMIC) settings. This paper describes how human-centered design (HCD) was used to 1) adapt a multifaceted implementation strategy for integrating HIV and NCD services through end-user engagement and 2) share insights from the specific sugge…
Differentiated community-based point-of-care early infant diagnosis to improve HIV diagnosis and ART initiation among infants and young children in Zambia
INTRODUCTION: An estimated 800 000 children (<15 years) globally living with HIV remain undiagnosed. To reach these children with timely HIV testing services during infancy, we implemented a community-based differentiated care model using mobile point-of-care (POC) technology for early infant diagnosis (EID) of HIV, and assessed its effects on EID positivity, antiretroviral therapy (ART) initiation and 3-month retention in care. METHODS: Between …
Beyond the pill
Women engaging in sex work (WESW) in low- and middle-income countries face a disproportionately high risk of HIV infection. This study explores enablers and barriers to the uptake and persistence of oral pre-exposure prophylaxis (PrEP) and long-acting injectable PrEP (LAI-PrEP) among WESW in Lusaka, Zambia. We evaluated Capability, Opportunity, and Motivation behavioral domains, using the COM-B model, which affectied behavioral engagement with Pr…
An exploration of multi-level factors affecting routine linkage to HIV care in Zambia’s Pepfar-supported treatment program in the treat all era
Multiple steps from HIV diagnosis to treatment initiation and confirmed engagement with the health system are required for people living with HIV to establish full linkage to care in the modern treat all era. We undertook a qualitative study to gain an in-depth understanding of the impeding and enabling factors at each step of this linkage pathway. In-depth interviews were conducted with fifty-eight people living with HIV recruited from ten routi…
Evaluating the impact of HIV pre-exposure prophylaxis on pregnancy, infant, and maternal health outcomes in Malawi
NCT06158126. The study was prospectively registered (5 December 2023) in ClinicalTrials.gov
Clinic presentation delay and tuberculosis treatment outcomes in the Lake Victoria region of East Africa
In the Lake Victoria region of East Africa, little is known about delays between tuberculosis (TB) symptom onset and presentation at a clinic. Associations between clinic presentation delay and TB treatment outcomes are also poorly understood. In 2019, we abstracted data from routine TB treatment records for all adults (n = 776) initiating TB treatment in a 6-month period across 12 health facilities near Lake Victoria. We interviewed 301 cohort m…
Geographic mobility and treatment outcomes among people in care for tuberculosis in the Lake Victoria region of East Africa
Geographic mobility may disrupt continuity of care and contribute to poor clinical outcomes among people receiving treatment for tuberculosis (TB). This may occur especially where health services are not well coordinated across international borders, particularly in lower and middle income country settings. In this work, we describe mobility and the relationship between mobility and unfavorable TB treatment outcomes (i.e., death, loss to follow-u…
Mitigating the effects of Covid-19 on HIV treatment and care in Lusaka, Zambia
INTRODUCTION: The Zambian Ministry of Health (MoH) issued COVID-19 mitigation guidance for HIV care immediately after the first COVID-19 case was confirmed in Zambia on 18 March 2020. The Centre for Infectious Disease Research in Zambia implemented MoH guidance by: 1) extending antiretroviral therapy (ART) refill duration to 6 multi-month dispensation (6MMD) and 2) task-shifting communication and mobilisation of those in HIV care to collect their…
Differences in Access to HIV Services and Risky Sexual Behaviors Among Malawian Women at Social Venues Who Do and Do Not Engage in Sex Work
“ Most of what they do, we cannot do !” How lay health workers respond to barriers to uptake and retention in HIV care among pregnant and breastfeeding mothers in Malawi
BACKGROUND: In the era of Option B+ and 'treat all' policies for HIV, challenges to retention in care are well documented. In Malawi, several large community-facility linkage (CFL) models have emerged to address these challenges, training lay health workers (LHW) to support the national prevention of mother-to-child transmission (PMTCT) programme. This qualitative study sought to examine how PMTCT LHW deployed by Malawi's three most prevalent CFL…
