The early detection and management of infections is crucial to control epidemics. We evaluated the feasibility and utility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen rapid diagnostic tests (Ag-RDTs) for the timely detection of and response to coronavirus disease 2019 in high-risk border communities in Uganda. Between May and September 2022, monthly cross-sectional surveys were conducted in 11 schools and two markets in two border districts.

Background: The overuse of antimicrobial medicines is a global health concern, including as a major driver of antimicrobial resistance. In many low- and middle-income countries, a substantial proportion of antibiotics are purchased over-the-counter without a prescription. But while antibiotics are widely available, information on when and how to use them is not.

Background: Evidence that house design can provide protection from malaria is growing. Housing modifications such as screening windows, doors, and ceilings, and attaching insecticide-impregnated materials to the eaves (the gap between the top of the wall and bottom of the roof), can protect against malaria. To be effective at scale, however, these modifications must be adopted by household residents.

The 'livestock revolution' has seen the lives and livelihoods of peri-urban peoples increasingly intertwine with pigs and poultry across Africa in response to a rising demand for meat protein. This 'revolution' heralds the potential to address both poverty and nutritional needs. However, the intensification of farming has sparked concern, including for antibiotic misuse and its consequences for antimicrobial resistance (AMR).

The ways in which dimensions of health and healthcare intersect with economics and politics in particular contexts requires close attention. In this article we connect concerns about antibiotic overuse in Uganda to the social milieu created through policies that follow President Museveni's vision for a population who , "tap wealth." Ethnographic fieldwork in rural Eastern Uganda illustrates how taking medicines in rural households reflects a wider landscape of everyday imperatives to "tap" opportunities in a context of acute precarity.

Faced with the threat of antimicrobial resistance, health workers are urged to reduce unnecessary prescription of antimicrobials. Clinical guidelines are expected to form the basis of prescribing decisions in practice. Emerging through evaluations of best practice - bundling clinical, technological and economic dimensions - guidelines also create benchmarks through which practice can be assessed with metrics.

Background: Intensive malaria control may have additional benefits beyond reducing the incidence of symptomatic malaria. We compared antibiotic treatment of children before and after the implementation of highly effective malaria control interventions in Tororo, a historically high transmission area of Uganda.

Methods: Two successive cohorts of children, aged 0.

Background: As concerns about the prevalence of infections that are resistant to available antibiotics increase, attention has turned toward the use of these medicines both within and outside of formal healthcare settings. Much of what is known about use beyond formal settings is informed by survey-based research. Few studies to date have used comparative, mixed-methods approaches to render visible patterns of use within and between settings as well as wider points of context shaping these patterns.

Background: Use of antibiotics to treat humans and animals is increasing worldwide, but evidence from low- and middle-income countries (LMICs) is limited. We conducted cross-sectional surveys in households and farms in Uganda to assess patterns of antibiotic use among humans and animals.

Methods: Between May and December 2018, a convenience sample of 100 households in Nagongera (rural), 174 households in Namuwongo (urban) and 115 poultry and piggery farms in Wakiso (peri-urban) were selected and enrolled.

Background: Demand for high-quality surveillance data for malaria, and other diseases, is greater than ever before. In Uganda, the primary source of malaria surveillance data is the Health Management Information System (HMIS). However, HMIS data may be incomplete, inaccurate or delayed.

There is increasing concern globally about the enormity of the threats posed by antimicrobial resistance (AMR) to human, animal, plant and environmental health. A proliferation of international, national and institutional reports on the problems posed by AMR and the need for antibiotic stewardship have galvanised attention on the global stage. However, the AMR community increasingly laments a lack of action, often identified as an 'implementation gap'.

Understanding the prevalence and types of antibiotics used in a given human and/or animal population is important for informing stewardship strategies. Methods used to capture such data often rely on verbal elicitation of reported use that tend to assume shared medical terminology. Studies have shown the category 'antibiotic' does not translate well linguistically or conceptually, which limits the accuracy of these reports.

Introduction: A large proportion of children with uncomplicated malaria receive appropriate treatment late, contributing to progression of illness to severe disease. We explored contexts of caregiver delays in seeking appropriate care for children with severe malaria.

Methods: This qualitative study was conducted at the Children's Ward of Jinja Hospital, where children with severe malaria were hospitalized.

In anthropology, interest in how values are created, maintained and changed has been reinvigorated. In this case study, we draw on this literature to interrogate concerns about the relationship between data collection and the delivery of patient care within global health. We followed a pilot study conducted in Kayunga, Uganda that aimed to improve the collection of health systems data in five public health centres.

Background: Rapid diagnostic tests for malaria (mRDTs) have been scaled-up widely across Africa. The PRIME study evaluated an intervention aiming to improve fever case management using mRDTs at public health centers in Uganda.

Methods: A cluster-randomized trial was conducted from 2010-13 in Tororo, a high malaria transmission setting.

Background: In Uganda, health system challenges limit access to good quality healthcare and contribute to slow progress on malaria control. We developed a complex intervention (PRIME), which was designed to improve quality of care for malaria at public health centres.

Objective: Responding to calls for increased transparency, we describe the PRIME intervention's design process, rationale, and final content and reflect on the choices and challenges encountered during the design of this complex intervention.

This article describes a theory-driven evaluation of one component of an intervention to improve the quality of health care at Ugandan public health centres. Patient-centred services have been advocated widely, but such approaches have received little attention in Africa. A cluster randomized trial is evaluating population-level outcomes of an intervention with multiple components, including 'patient-centred services.

Health systems in many African countries are failing to provide populations with access to good quality health care. Morbidity and mortality from curable diseases such as malaria remain high. The PRIME trial in Tororo, rural Uganda, designed and tested an intervention to improve care at health centres, with the aim of reducing ill-health due to malaria in surrounding communities.

Background: Despite significant investments into health improvement programmes in Uganda, health indicators and access to healthcare remain poor across the country. The PRIME trial aims to evaluate the impact of a complex intervention delivered in public health centres on health outcomes of children and management of malaria in rural Uganda. The intervention consists of four components: Health Centre Management; Fever Case Management; Patient- Centered Services; and support for supplies of malaria diagnostics and antimalarial drugs.

Objectives: The deployment of new antimalarials in Africa provides an important opportunity to develop systems for pharmacovigilance. To inform strategies for reporting adverse events in Uganda, we investigated local perceptions and experiences with antimalarial treatment, and evaluated existing and potential systems for pharmacovigilance.

Methods: Focus group discussions (FGD) were conducted with community members and health workers from urban and rural Uganda exploring knowledge of fever/malaria, perceptions and expectations of treatment, understanding of adverse effects, and experiences with adverse events.
