  • Soil-transmitted helminths and schistosomiasis among pre-school age children in a rural setting of Busia County, Western Kenya

    Open AccessJanet Masaku, Doris W Njomo et al.ARTICLEBMC Public Health2020

    There was high prevalence of STH infection among enrolled PSAC despite having participated in the national school-based deworming programme. Hence the need for continued mass drug administration to reduce the intensity of infections among these age group. In addition, further research maybe needed to identify drivers of STH infection particularly T. trichiura among PSAC

  • The Wash Benefits and SHINE trials

    Open AccessAmy J Pickering, Clair Null et al.ARTICLEThe Lancet Global Health2019

    Child stunting is a global problem and is only modestly responsive to dietary interventions. Numerous observational studies have shown that water quality, sanitation, and handwashing (WASH) in a household are strongly associated with linear growth of children living in the same household. We have completed three randomised efficacy trials testing improved household-level WASH with and without improved infant and young child feeding (IYCF) on stun…

  • Effects of water quality, sanitation, handwashing, and nutritional interventions on diarrhoea and child growth in rural Kenya

    Open AccessClair Null, Christine P Stewart et al.ARTICLEThe Lancet Global Health2018

    Background Poor nutrition and exposure to faecal contamination are associated with diarrhoea and growth faltering, both of which have long-term consequences for child health. We aimed to assess whether water, sanitation, handwashing, and nutrition interventions reduced diarrhoea or growth faltering. Methods The WASH Benefits cluster-randomised trial enrolled pregnant women from villages in rural Kenya and evaluated outcomes at 1 year and 2 years …

  • 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 AccessCollins Okoyo, Elses Simiyu et al.ARTICLEBMC Public Health2018

    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…

  • Retracted Article

    Open AccessJudy Mwai, Sammy M Njenga et al.ARTICLEBMC Public Health2016

    This study reveals that knowledge about the cause, transmission, symptoms and prevention of schistosomiasis among the Mwea population was inadequate, and that this could be a challenging obstacle to the elimination of schistosomiasis in these communities. Due to various dominant risk factors, different control strategies should be designed. Therefore, there is a need for integrated control programme to have a lasting impact on transmission of sch…

  • Current status of Schistosoma mansoni and the factors associated with infection two years following mass drug administration programme among primary school children in Mwea irrigation scheme

    Open AccessJanet Masaku, Nancy Madigu et al.ARTICLEBMC Public Health2015

    There was high prevalence of S. mansoni infections in the study area, two years after the withdrawal of MDA programme. We suggest that treatment should be continued in the school children at regular intervals, monitoring and surveillance intensified to ensure interruption of transmission areas
