Exploring smallholder farmers’ access and participation in the Home Grown School Feeding Programme in selected counties of Kenya
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…
The role of molecular xenomonitoring for assessing the impact of Ivermectin, Diethylcarbamazine Citrate and Albendazole triple-drug treatment against lymphatic filariasis
Lymphatic Filariasis (LF) is a mosquito-borne disease primarily caused by the filarial parasite Wuchereria bancrofti . The triple-drug therapy of Ivermectin, Diethylcarbamazine Citrate and Albendazole (IDA) has been adopted to accelerate LF elimination of LF as a public health problem, particularly in areas where onchocerciasis is not co-endemic. In Kenya, IDA was administered to endemic communities in Jomvu sub-County (Mombasa) and Lamu County i…
Barriers and facilitators of care among visceral leishmaniasis patients following the implementation of a decentralized model in Turkana County, Kenya
Turkana County is among the eleven counties in Kenya endemic for Visceral Leishmaniasis (VL). Early diagnosis and management is crucial to improving quality of life, reducing related morbidity and mortality, and disease transmission. In Turkana County, Foundation for Innovative New Diagnostics (FIND) has undertaken significant work in supporting the decentralization of access to VL treatment. Despite this decentralization efforts, barriers to acc…
Piloting lymphoedema management for lymphatic filariasis
Training of health care providers, caregivers and patients using the developed intervention care package contributed to improved knowledge on cause and management of lymphoedema. The CHVs played a critical role in the identification and referral of patients, which contributed to improved health-care seeking behaviour and increased service utilization. Collaboration with the county health authorities contributed to improved quality of health care …
Prevalence and predictors of anemia among six-week-old infants in Kwale County, Kenya
Anemia is a significant public health problem among children worldwide. The etiology of anemia is multifactorial but iron deficiency (ID) is the most common cause of anemia in low- and middle-income countries. ID and anemia in infancy can impair growth and cognitive development. The aim of this study was to determine the prevalence and predictors of anemia among six-week-old infants in Kwale County, Kenya. This cross-sectional study included 424 …
Helminthiasis and malaria co-infection among women of reproductive age in a rural setting of Kilifi County, coastal Kenya
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
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
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
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
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…
Soil-transmitted helminths and schistosomiasis among pre-school age children in a rural setting of Busia County, Western Kenya
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
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
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…
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
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
