  • Design of an implementation research study for a digital omnichannel community engagement and risk communication intervention for the prevention and control of vector-borne diseases in India

    Open AccessRashmi Rodrigues, Amey Dhatrak et al.ARTICLEFrontiers in Public Health2026

    Introduction: Vector-borne diseases (VBDs), such as malaria, dengue, and lymphatic filariasis, pose significant public health challenges in India, contributing significantly to the nation's morbidity and mortality. In this scenario, digital technology promises scalable, contextual, and user-centric interventions for behavior change. However, systematic and comprehensive community-based digital approaches for VBD prevention in India are limited. T…

  • Hygiene knowledge and practices in the Lagos wild meat value chain

    Open AccessSamuel N Akpan, Elizabeth A J Cook et al.ARTICLEPLOS Global Public Health2026

    Wild meat, commonly known as bushmeat, is a cultural, economic, and nutritional staple food in many regions of the world, including sub-Saharan Africa. Wild meat value chains face major hygiene and sanitary regulation challenges, but only a few studies have investigated these challenges, focusing instead on market dynamics and biodiversity issues. This study examines the hygiene practices, attitudes, perceptions, and knowledge of public health ri…

  • Demographic and socioeconomic characteristics associated with Sars-CoV-2 reinfection

    Open AccessNatasha Nicos Ferreira, Pedro Manoel Marques Garibaldi et al.ARTICLEPLOS Global Public Health2026

    Since SARS-CoV-2 emergence, risk factors for reinfection have not been totally determined. In this cohort, we analyzed the monthly incidence and outcomes of COVID-19 reinfection and its association with variants of concern, demographic, and socioeconomic factors. An infection case was defined as a positive test for SARS-CoV-2 and reinfection as the presence of a new positive test after 90 days or more of the previous infection. From September 1, …

  • Evidence needs and community involvement in policy decisions for vaccine-preventable diarrhoeal infections among children under the age of five years

    Open AccessChikondi A Mwendera, Maxwell Phiri et al.ARTICLEPLOS Global Public Health2025

    Diarrhoeal diseases are a leading cause of morbidity and mortality among children under five years in low- and middle-income countries (LMICs) with Shigella and Enterotoxigenic Escherichia coli (ETEC), both targets of ongoing vaccine development, playing major roles. To inform the introduction of vaccines against these pathogens in Ethiopia, Kenya, and Malawi, we assessed evidence needs for technical policy decisions and community engagement in n…

  • The occurrence of cross-host species soil-transmitted helminth infections in humans and domestic/livestock animals

    Open AccessUniqueky Gratis Mawrie, Riviarynthia Kharkongor et al.ARTICLEPLOS Global Public Health2025

    Zoonotic soil-transmitted helminths (STH), including Ancylostoma ceylanicum , Ancylostoma caninum , Ancylostoma braziliense , Trichuris vulpis , Trichuris suis , and Ascaris suum , are increasingly recognised as potential sources of human infection. Additionally, animals can act as carriers or reservoirs for human STH species. However, the extent of cross-host infection remains poorly understood, primarily due to reliance on morphological diagnos…

  • Who participates in ‘participatory design’ of Wash infrastructure

    Open AccessThea Mink, Allison P Salinger et al.ARTICLEPLOS Global Public Health2025

    Inclusive participation is critical for community-based water, sanitation and hygiene (WASH) interventions, especially in complex environments such as urban informal settlements. We conducted a mixed-methods, theory-driven process evaluation to evaluate participation, barriers to participation, and participant satisfaction within the Revitalising Informal Settlements and their Environments (RISE) trial in Makassar, Indonesia and Suva, Fiji (ACTRN…

  • Association between peripheral markers in women with malaria in pregnancy and small newborns

    Open AccessMaria Inês dos Santos, Alexsander Rodrigues Carvalho Júnior et al.ARTICLEPLOS Global Public Health2025

    Alterations in angiogenic proteins play a role in newborn growth potential, and they have been widely studied, but not further explored in malaria research. We aimed to identify maternal peripheral proteins that are associated with newborn growth parameters in the context of malaria in pregnancy. We analysed data and biological samples collected from 386 pregnant women with and without malaria selected from previous cohort study in the Amazon reg…

  • Low-cost, local production of a safe and effective disinfectant for resource-constrained communities

    Open AccessAndrea Naranjo-Soledad, Logan Smesrud et al.ARTICLEPLOS Global Public Health2024

    Improved hygiene depends on the accessibility and availability of effective disinfectant solutions. These disinfectant solutions are unavailable to many communities worldwide due to resource limitations, among other constraints. Safe and effective chlorine-based disinfectants can be produced via simple electrolysis of salt water, providing a low-cost and reliable option for on-site, local production of disinfectant solutions to improve sanitation…

  • Assessment of sewer connectivity in the United States and its implications for equity in wastewater-based epidemiology

    Open AccessQinQin Yu, Scott W Olesen et al.ARTICLEPLOS Global Public Health2024

    Wastewater-based epidemiology is a promising public health tool that can yield a more representative view of the population than case reporting. However, only about 80% of the U.S. population is connected to public sewers, and the characteristics of populations missed by wastewater-based epidemiology are unclear. To address this gap, we used publicly available datasets to assess sewer connectivity in the U.S. by location, demographic groups, and …

  • Understanding Covid-19 vaccine hesitancy in Meghalaya, India

    Open AccessSooyoung Kim, Rajiv Sarkar et al.ARTICLEPLOS Global Public Health2024

    Meghalaya, a state in the northeastern region of India, had a markedly low vaccine uptake compared to the other states in the country when COVID-19 vaccines were being rolled out in 2021. This study aimed to characterize the distinct vaccine-hesitant subpopulations in healthcare and community settings in Meghalaya state in the early days of the vaccination program. We used data from a cross-sectional survey that was administered to 200 healthcare…

  • Water and war

    Open AccessRohini J Haar, Bartolomé Freire Arteta et al.ARTICLEPLOS Global Public Health2023

    Since 2011, Syria has been engulfed in a complex conflict marked by both targeted and indiscriminate attacks on civilians and civilian infrastructure. Water infrastructure has been continuously targeted, exacerbating problems with contamination of and access to clean adequate drinking water, and increasing the risk of waterborne diseases. We aimed to determine whether having access to more functional and chlorinated water stations is associated w…

  • The burden of risk factors for non-communicable disease in rural Bihar, India

    Open AccessStephanie Ross, Kashika Chadha et al.ARTICLEBMC Public Health2022

    The prevalence of NCDs in rural India is higher than previously reported due to the older demographic in our survey.
