Public health emergencies can disrupt the provision of and access to essential health-care services, exacerbating crises. We aimed assess effect COVID-19 pandemic on services in Kenya.Using county-level data routinely collected from information system facilities across country, we used a robust mixed-effect model examine changes 17 indicators four periods: pre-pandemic period (from January, 2018 February, 2020), two periods March November 2020, February October, 2021), during...
Abstract Middle East respiratory syndrome coronavirus (MERS-CoV) is endemic in dromedaries Africa, but camel-to-human transmission limited. Sustained 12-month sampling of a Kenya abattoir hub showed biphasic MERS-CoV incidence; peak detections occurred October 2022 and February 2023. Dromedary-exposed workers (7/48) had serologic signs previous exposure.
Background: Soil transmitted helminths (STH) remain a significant public health challenge in Africa. The absence of high-resolution prevalence maps hampers countries' ability to tailor mass drug administration (MDA) programs address localised variations disease burden. We aimed estimate and map STH Kenya identify high- low-burden communities effectively target interventions. Methods: used data collected from 146,668 children 3,752 schools 207 subcounties 90 wards 2020, 2021 2024. Site-level...
ABSTRACT Proper nutrition is vital for maintaining good health all people across their lifespan, especially children and mothers, who are vulnerable due to specific nutrient needs. Despite the necessity of improved these groups, some members do not fully meet recommended daily micronutrient needs, a challenge exacerbated by different socioeconomic, cultural, communal constraints resulting in malnutrition. Iron deficiency anaemia major concern among pastoralist communities, poor other related...
East Coast Fever (ECF) is one of the leading causes livestock mortality and reduced productivity across Eastern Africa, while a live vaccine against it known as Infection Treatment Method has existed for three decades now, its adoption by affected communities remains low. This study sought to provide detailed examination dynamics that shape (ITM) behaviours. The examined individual, socio-cultural ecological- level factors influencing ITM using socio-ecological model. Analyzing data obtained...
The use of advanced analytics in public health policy remains hindered by a disconnect between researchers, policymakers, and technical experts. Bridging this gap requires intentional knowledge translation strategies that facilitate interdisciplinary collaboration real-world application research findings. Hackathons, which bring together diverse stakeholders time-bound, solution-oriented format, offer an approach to addressing challenge. In January 2025, the MRC Centre for Global Infectious...
Cholera is a public health challenge in Kenya. This study aimed at identifying the spatio-temporal pattern of cholera and its associated risk factors high-risk areas to optimize resource use for targeted control. The was conducted Mukuru, an informal settlement, Dadaab refugee camp counties bordering Lake Victoria. line list data from 32 subcounties (2013-2022) sourced Kenya's Ministry Health.

Today, the world counts millions of refugees but only a fraction them have access to higher education. Despite multiple public health problems in refugee camps and need build local capacities prevent combat them, University level courses are largely unavailable for refugees. This paper describes development, implementation evaluation an innovative two-module blended-learning programme on One Health Kakuma camp (Kenya). combines: (I) Interdisciplinary multi-expert MOOC "
The 2030 target for schistosomiasis is elimination as a public health problem (EPHP), achieved when the prevalence of heavy-intensity infection among school-aged children (SAC) reduces to <1%. To achieve this, new World Health Organization guidelines recommend broader population include pre-SAC and adults. However, probability achieving EPHP should be expected depend on patterns in repeated uptake mass drug administration by individuals.
Objectives To assess outcomes of patients admitted to hospital with COVID-19 and determine the predictors mortality. Setting This study was conducted in six facilities, which included both government privately run secondary tertiary level facilities central coastal regions Kenya. Participants We enrolled 787 reverse transcriptase-PCR-confirmed SARS-CoV2-infected persons. Patients whose records could not be accessed were excluded. Primary outcome measures The primary COVID-19-related death....
Abstract Nearly a century after the first reports of Rift Valley fever (RVF) were documented in Kenya, questions on transmission dynamics disease remain. Specifically, data viral maintenance quiescent years between epidemics is limited. We implemented cross-sectional study northern Kenya to determine seroprevalence, risk factors, and ecological predictors RVF humans livestock during an interepidemic period. Six hundred seventy-six human 1,864 samples screened for anti-RVF Immunoglobulin G...
Camels are increasingly becoming the livestock of choice for pastoralists reeling from effects climate change in semi-arid and arid parts Kenya. As population camels rises, better understanding their role epidemiology zoonotic diseases Kenya is a public health priority. Rift Valley fever (RVF), brucellosis Q three top priority country but involvement transmission dynamics these poorly understood. We analyzed 120 camel serum samples northern to establish seropositivity rates pathogens...
Abstract Over the past decade, considerable progress has been made in control, elimination, and eradication of neglected tropical diseases (NTDs). Despite these advances, most NTD programs have recently experienced important setbacks; for example, interventions were some frequently severely impacted by service disruptions due to coronavirus disease 2019 (COVID-19) pandemic. Mathematical modeling can help inform selection meet targets set out road map 2021–2030, such studies should prioritize...
Whilst there are longstanding and well-established inequalities in safe-drinking water-access between urban rural areas, remain few studies of changing intra-urban over time. In this study, we determined the spatio-temporal patterns domestic piped water distribution Nairobi, Kenya 1985 2018, implications socio-economic neighbourhood sufficiency. Using data from Nairobi sewerage utility company for period 2008–2018, examined sufficiency monthly consumption per capita 2380 itineraries (areas...
Coxiella burnetti can be transmitted to humans primarily through inhaling contaminated droplets released from infected animals or consumption of dairy products. Despite its zoonotic nature and the close association pastoralist communities have with their livestock, studies reporting simultaneous assessment C. exposure risk-factors among people livestock are scarce.This study therefore estimated seroprevalence Q-fever associated risk factors in livestock.We conducted a cross-sectional...
The prompt administration of post-exposure prophylaxis (PEP) is one the key strategies for ending human deaths from rabies. A delay in seeking first dose rabies PEP, or failure to complete recommended dosage, may result clinical and death. We assessed efficacy short message system (SMS) phone texts improving adherence scheduled PEP doses among bite patients rural eastern Kenya. conducted a single-arm, before-after field trial that compared presenting at Makueni Referral Hospital between...
Brucellosis is associated with massive livestock production losses and human morbidity worldwide. Efforts to control brucellosis among pastoralist communities are limited by scarce data on the prevalence risk factors for exposure despite high human-animal interactions in these communities. This study simultaneously assessed seroprevalence of pastoralists their same households.We conducted a cross-sectional Marsabit County - Kenya. A total 1,074 women 225 children participated provided blood...
Background Inadequate food intake is the most common cause of malnutrition worldwide. There paucity knowledge on influence farming systems, a proxy for contextualizing community-based networks, and sociocultural perspectives necessary creating impactful nutritional programs policies young children from infancy to early childhood in Kenya their mothers, especially Kenya. This study sought evaluate nutrient intakes mothers Pastoral, Agro-pastoral Mixed system Methods Mothers were recruited...
