  • Malaria entomological surveillance in Kinshasa Province

    Open AccessFabien Vulu, Melchior M Kashamuka et al.ARTICLEPLOS Global Public Health2026

    Malaria remains a major public health challenge in the Democratic Republic of Congo. To address the lack of contemporary entomological data, this four-year study characterized key entomological parameters in Kinshasa Province. We conducted a prospective observational cohort study (2018-2022) in three health areas. Adult mosquitoes were sampled using CDC light traps and pyrethrum spray catches. Sporozoite rates were estimated using ELISA, and trap…

  • Spatially heterogeneous and neighborhood impacts of deep tubewells on childhood diarrhea in rural Bangladesh

    Open AccessVarun Goel, Mark M Janko et al.ARTICLESocial Science & Medicine2026

    Deep tubewells that procure groundwater from deep arsenic-free aquifers are crucial sources of safe drinking-water in rural Bangladesh. However, their health benefits may be heterogeneous and context dependent: inequitable distribution, long collection distances and continued use of unsafe alternatives may increase microbial contamination and diarrheal disease. We examined whether the association between household deep tubewell use and under-five…

    Our paper describes the development of the disease ecology tradition of health and medical geography including some key themes and a few recent innovations. The four commentaries by a distinguished set of scholars add more background to this tradition and offer many useful opinions about productive areas of inquiry that this tradition has and should focus on. Our paper does not provide history, themes and areas of innovation to the entire subdisc…

  • Disease ecology in health and medical geography

    Open AccessMichael Emch, Varun GoelARTICLESingapore Journal of Tropical…2026Citada por: 2Referências: 95

    This paper describes the development of the disease ecology tradition of health and medical geography including some key themes and innovations. It first grounds disease ecology in the history of ecology from the natural sciences and the human ecology traditions within the social sciences. These ecological studies of disease developed in response to limitations in the biomedical approach to studying health and disease that developed after germ th…

  • Geospatial and phylogenetic clustering of acute and recent HIV infections in Lilongwe, Malawi

    Open AccessGordon J Bell, Kimberly A Powers et al.ARTICLEPLOS Global Public Health2025

    HIV transmission during early HIV infection impedes efforts to end HIV as a public health threat, as diagnosis typically occurs after this period of elevated transmission risk. To guide diagnosis and prevention strategies, we evaluated the geospatial and phylogenetic clustering of acute and recent HIV infection in Lilongwe, Malawi. We identified people with acute (pre-seroconversion) HIV infection (AHI) and a random sample of people with post-acu…

  • Geographic dimensions of gastric cancer risk in western Honduras

    Open AccessKari Brandt, Katerina E B Beach et al.ARTICLEHealth & Place2025

    Gastric cancer is fifth most common cancer globally, with a complex and multifactorial etiology, including human and bacterial genetics, health behaviors, and environmental exposures. Honduras has among the highest rates of gastric cancer in the western hemisphere, and previous research indicates that gastric cancer risk varies geographically at a sub-national scale. We analyzed characteristics of all 788 incident cases diagnosed in western Hondu…

  • A pyramid of human ecology of disease for pandemic preparedness

    Open AccessSiu Leung Li, Michael EmchARTICLESocial Science & Medicine2025Referências: 104

    The emergence of zoonotic infectious diseases and its potential threat to future health security highlights the need to re-examine how we conceptualize the impact of human-environment interactions on health. Traditionally, social scientists, epidemiologists, and ecologists have used the human ecology frameworks to understand disease dynamics, framing health outcomes as the result of interactions between population, habitat, and behaviour. However…

  • Private sector antimalarial sales a decade after “test and treat”

    Open AccessVictoria Shelus, Nobert Mumbere et al.ARTICLEFrontiers in Public Health2023

    Background: The World Health Organization has promoted "test and treat" guidelines for malaria since 2010, recommending all suspected malaria cases be confirmed with a parasitological test, typically a rapid diagnostic test (RDT), prior to treatment with antimalarial medications. However, many fevers at private drug shops in Uganda continue to be treated presumptively as malaria without diagnostic testing. Methods: = 46) recorded information abou…

  • Impact of malaria diagnostic choice on monitoring of Plasmodium falciparum prevalence estimates in the Democratic Republic of the Congo and relevance to control programs in high-burden countries

    Open AccessAlpha Oumar Diallo, Kristin Banek et al.ARTICLEPLOS Global Public Health2023

    Malaria programs rely upon a variety of diagnostic assays, including rapid diagnostic tests (RDTs), microscopy, polymerase chain reaction (PCR), and bead-based immunoassays (BBA), to monitor malaria prevalence and support control and elimination efforts. Data comparing these assays are limited, especially from high-burden countries like the Democratic Republic of the Congo (DRC). Using cross-sectional and routine data, we compared diagnostic perf…

  • Clinic presentation delay and tuberculosis treatment outcomes in the Lake Victoria region of East Africa

    Open AccessGrace E Mulholland, Michael E Herce et al.ARTICLEPLOS Global Public Health2023

    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

    Open AccessGrace E Mulholland, Michael E Herce et al.ARTICLEPLOS Global Public Health2023

    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…

  • “Testing for malaria does not cure any pain” A qualitative study exploring low use of malaria rapid diagnostic tests at drug shops in rural Uganda

    Open AccessVictoria Shelus, Nobert Mumbere et al.ARTICLEPLOS Global Public Health2022

    The World Health Organization recommends all suspected malaria cases be confirmed with a parasitological test, typically a rapid diagnostic test (RDT), prior to treatment. Despite recommendations, many fevers presenting at private drug shops are treated presumptively as malaria without diagnostic testing. The purpose of this qualitative study was to describe community perceptions of RDTs and explore ways to improve malaria case management at drug…

  • Effectiveness of a national mass distribution campaign of long-lasting insecticide-treated nets and indoor residual spraying on clinical malaria in Malawi, 2018–2020

    Open AccessHillary Mariko Topazian, Austin Gumbo et al.ARTICLEBMJ Global Health2021

    INTRODUCTION: Malawi's malaria burden is primarily assessed via cross-sectional national household surveys. However, malaria is spatially and temporally heterogenous and no analyses have been performed at a subdistrict level throughout the course of a year. The WHO recommends mass distribution of long-lasting insecticide-treated bed nets (LLINs) every 3 years, but a national longitudinal evaluation has never been conducted in Malawi to determine …

  • Estimating exposure to neighborhood crime by race and ethnicity for public health research

    Open AccessEvans K Lodge, Cathrine Hoyo et al.ARTICLEBMC Public Health2021

    Public health researchers should give thoughtful consideration when using police-reported crime data to measure and model exposure to crime in the United States, as police-reported data encompasses joint exposure to police and crime in the neighborhood setting

  • Spatial and epidemiological drivers of Plasmodium falciparum malaria among adults in the Democratic Republic of the Congo

    Open AccessMolly Deutsch-Feldman, Nicholas F Brazeau et al.ARTICLEBMJ Global Health2020

    BACKGROUND: Adults are frequently infected with malaria and may serve as a reservoir for further transmission, yet we know relatively little about risk factors for adult infections. In this study, we assessed malaria risk factors among adults using samples from the nationally representative, cross-sectional 2013-2014 Demographic and Health Survey (DHS) conducted in the Democratic Republic of the Congo (DRC). We further explored differences in ris…

  • Considering Alternate Pathways of Drinking-Water Contamination

    Open AccessVarun Goel, Gordon J Bell et al.ARTICLEInternational Journal of…2020

    Deep tubewells are a key component of arsenic mitigation programs in rural Bangladesh. Compared to widely prevalent shallow tubewells, deep tubewells reduce ground-water arsenic exposure and provide better microbial water quality at source. However, the benefits of clean drinking-water at these more distant sources may be abated by higher levels of microbial contamination at point-of-use. One such potential pathway is the use of contaminated surf…
