  • Exploring smallholder farmers’ access and participation in the Home Grown School Feeding Programme in selected counties of Kenya

    Open Access•Joyce Kamau, Collins Okoyo et al.•ARTICLE•Frontiers in Public Health•2025

    Introduction: Smallholder farmers (SHFs) produce 80% of the total agricultural output in Kenya. The Home Grown School Feeding Programme (HGSFP) was designed to address short-term hunger among primary school children from food-insecure households, enhancing access to primary education while providing a market to SHFs through local procurement of food for schools. This study investigated SHF access and participation in the HGSFP market and the upta…

  • Better floors, better health

    Open Access•Stella Kepha, Hugo Legge et al.•ARTICLE•BMC Public Health•2025

    This study presents a theory of change framework mapping the pathways through which an improved flooring intervention may impact health and wellbeing. The results can be of use to researchers or programmes that are in the design or evaluation phase of a household flooring project in Kenya or other settings where access to improved floors is limited

  • Helminthiasis and malaria co-infection among women of reproductive age in a rural setting of Kilifi County, coastal Kenya

    Open Access•Janet Masaku, Francis Mutuku et al.•ARTICLE•PLOS Global Public Health•2024

    Soil transmitted helminthiasis (STH), Schistosoma haematobium and malaria co-infection lead to increased susceptibility to other infections and poor pregnancy outcomes among women of reproductive age (WRA). This study sought to establish risk factors, burden of co-infection with STH, S . haematobium and Plasmodium sp. among WRA in Kilifi County, Kenya.A mixed method cross-sectional study was conducted on 474 WRA in 2021. Simple random sampling wa…

  • Sensitivity Analysis of a Transmission Interruption Model for the Soil-Transmitted Helminth Infections in Kenya

    Open Access•Collins Okoyo, Nelson Owuor Onyango et al.•ARTICLE•Frontiers in Public Health•2022

    As the world rallies toward the endgame of soil-transmitted helminths (STH) elimination by the year 2030, there is a need for efficient and robust mathematical models that would enable STH programme managers to target the scarce resources and interventions, increase treatment coverage among specific sub-groups of the population, and develop reliable surveillance systems that meet sensitivity and specificity requirements for the endgame of STH eli…

  • Schistosomiasis, soil transmitted helminthiasis, and malaria co-infections among women of reproductive age in rural communities of Kwale County, coastal Kenya

    Open Access•Victor Tunje Jeza, Francis Mutuku et al.•ARTICLE•BMC Public Health•2022

    The use of improved WASH activities might have contributed to the low prevalence of STHs and S. haematobium infections. Further, bed net ownership and usage might have resulted in the low prevalence of Plasmodium sp. infections observed

  • Modeling the Interruption of the Transmission of Soil-Transmitted Helminths Infections in Kenya

    Open Access•Collins Okoyo, Graham Medley et al.•ARTICLE•Frontiers in Public Health•2021

    Kenya, just like other countries with endemic soil-transmitted helminths (STH), has conducted regular mass drug administration (MDA) program for the last 5 years among school aged children as a way to reduce STH infections burden in the country. However, the point of interruption of transmission of these infections still remains unclear. In this study, we developed and analyzed an age structured mathematical model to predict the elimination perio…

  • Prevalence and Correlation Analysis of Soil-Transmitted Helminths Infections and Treatment Coverage for Preschool and School Aged Children in Kenya

    Open Access•Collins Okoyo, Suzy J Campbell et al.•ARTICLE•Frontiers in Public Health•2021

    Background: Soil-transmitted helminths (STH) are among the most common parasitic infections globally, disproportionately affecting children. Treatment of STH in Kenya is often targeted at preschool (PSAC) and school aged (SAC) children delivered through annual mass drug administration (MDA) in primary schools. Understanding group-specific prevalence and dynamics between treatment and coverage is critical for continued treatment success. This stud…

  • Comparing the performance of circulating cathodic antigen and Kato-Katz techniques in evaluating Schistosoma mansoni infection in areas with low prevalence in selected counties of Kenya

    Open Access•Collins Okoyo, Elses Simiyu et al.•ARTICLE•BMC Public Health•2018

    Kato-Katz technique has been the mainstay test in Schistosoma mansoni diagnosis in endemic areas. However, recent studies have documented its poor sensitivity in evaluating Schistosoma mansoni infection especially in areas with lower rates of transmission. It’s the primary diagnostic tool in monitoring impact of the Kenya national school based deworming program on infection transmission, but there is need to consider a more sensitive technique as…
