Characterization of COVID-19 cases in the early phase (March to July 2020) of the pandemic in Kenya.

Background: Kenya detected the first case of COVID-19 on March 13, 2020, and as of July 30, 2020, 17 975 cases with 285 deaths (case fatality rate (CFR) = 1.6%) had been reported. This study described the cases during the early phase of the pandemic to provide information for monitoring and response planning in the local context. Methods: We reviewed COVID-19 case records from isolation centres while considering national representation and the WHO sampling guideline for clinical characterization of the COVID-19 pandemic within a country. Socio-demographic, clinical, and exposure data were summarized using median and mean for continuous variables and proportions for categorical variables. We assigned exposure variables to socio-demographics, exposure, and contact data, while the clinical spectrum was assigned outcome variables and their associations were assessed. Results: A total of 2796 case records were reviewed including 2049 (73.3%) male, 852 (30.5%) aged 30-39 years, 2730 (97.6%) Kenyans, 636 (22.7%) transporters, and 743 (26.6%) residents of Nairobi City County. Up to 609 (21.8%) cases had underlying medical conditions, including hypertension (n = 285 (46.8%)), diabetes (n = 211 (34.6%)), and multiple conditions (n = 129 (21.2%)). Out of 1893 (67.7%) cases with likely sources of exposure, 601 (31.8%) were due to international travel. There were 2340 contacts listed for 577 (20.6%) cases, with 632 contacts (27.0%) being traced. The odds of developing COVID-19 symptoms were higher among case who were aged above 60 years (odds ratio (OR) = 1.99, P = 0.007) or had underlying conditions (OR = 2.73, P < 0.001) and lower among transport sector employees (OR = 0.31, P < 0.001). The odds of developing severe COVID-19 disease were higher among cases who had underlying medical conditions (OR = 1.56, P < 0.001) and lower among cases exposed through community gatherings (OR = 0.27, P < 0.001). The odds of survival of cases from COVID-19 disease were higher among transport sector employees (OR = 3.35, P = 0.004); but lower among cases who were aged ≥60 years (OR = 0.58, P = 0.034) and those with underlying conditions (OR = 0.58, P = 0.025). Conclusion: The early phase of the COVID-19 pandemic demonstrated a need to target the elderly and comorbid cases with prevention and control strategies while closely monitoring asymptomatic cases.

Legal and institutional foundations for universal health coverage, Kenya.

Kenya's Constitution of 2010 triggered a cascade of reforms across all sectors to align with new constitutional standards, including devolution and a comprehensive bill of rights. The constitution acts as a platform to advance health rights and to restructure policy, legal, institutional and regulatory frameworks towards reversing chronic gaps and improving health outcomes. These constitutionally mandated health reforms are complex. All parts of the health system are transforming concurrently, with several new laws enacted and public health bodies established. Implementing such complex change was hampered by inadequate tools and approaches. To gain a picture of the extent of the health reforms over the first 10 years of the constitution, we developed an adapted health-system framework, guided by World Health Organization concepts and definitions. We applied the framework to document the health laws and public bodies already enacted and currently in progress, and compared the extent of transformation before and after the 2010 Constitution. Our analysis revealed multiple structures (laws and implementing public bodies) formed across the health system, with many new stewardship structures aligned to devolution, but with fragmentation within the regulation sub-function. By deconstructing normative health-system functions, the framework enabled an all-inclusive mapping of various health-system attributes (functions, laws and implementing bodies). We believe our framework is a useful tool for countries who wish to develop and implement a conducive legal foundation for universal health coverage. Constitutional reform is a mobilizing force for large leaps in health institutional change, boosting two aspects of feasibility for change: stakeholder acceptance and authority to proceed.

Adoptée en 2010, la Constitution du Kenya a entraîné une série de réformes dans tous les secteurs afin de les adapter aux nouvelles normes constitutionnelles, notamment à la décentralisation et à une charte détaillée des droits. La Constitution sert de tremplin pour faire progresser les droits en matière de santé et restructurer les cadres politiques, juridiques, institutionnels et réglementaires en vue de réduire les disparités chroniques et d'améliorer les résultats cliniques. Toutefois, ces réformes de santé prévues dans la Constitution sont complexes. Toutes les composantes du système de santé évoluent en même temps, de nombreuses lois inédites sont promulguées et des organismes de santé publique sont créés. L'emploi d'approches et d'outils inadaptés a entravé la mise en œuvre de ces changements si complexes. Pour mieux appréhender l'étendue des réformes de santé entreprises au cours des 10 premières années de la Constitution, nous avons développé un cadre sanitaire sur mesure, inspiré des concepts et définitions de l'Organisation mondiale de la Santé. Nous avons appliqué ce cadre afin de récolter des données sur les organismes publics et les lois relatives à la santé qui ont d'ores et déjà été édictées ou sont en cours d'élaboration, et avons comparé l'ampleur des transformations avant et après la Constitution de 2010. Notre analyse a révélé de multiples structures (lois et organes publics de mise en œuvre) réparties dans l'ensemble du système de santé, avec plusieurs nouvelles structures de gestion conformes à la décentralisation mais une fragmentation au niveau de la sous-fonction de régulation. En décomposant les fonctions normatives du système de santé, le cadre a permis d'établir une cartographie globale des différentes caractéristiques de ce système (fonctions, lois et organes de mise en œuvre). Nous sommes convaincus que notre cadre représente un outil utile pour les pays qui souhaitent développer et instaurer des bases juridiques propices à la création d'une couverture maladie universelle. La réforme constitutionnelle possède un pouvoir de mobilisation capable de faire progresser le changement institutionnel dans le domaine de la santé. Et ce, en renforçant deux aspects qui favorisent sa réalisation: l'acceptation de la part des intervenants, et l'autorité nécessaire pour agir.

La Constitución de Kenia de 2010 generó una serie de reformas en todos los sectores para ajustarse a los nuevos estándares constitucionales, incluida la transmisión y una amplia carta de derechos. La constitución representa una plataforma para promover los derechos sobre la salud y reestructurar los marcos jurídicos, institucionales y normativos con el fin de revertir las deficiencias crónicas y mejorar los resultados de la salud. Estas reformas de la salud, establecidas por mandato constitucional, son complejas. Asimismo, todas las áreas del sistema de salud se están transformando de manera simultánea, ya que se han promulgado varias leyes nuevas y se han establecido organismos de salud pública. Sin embargo, la falta de herramientas y métodos adecuados limitó la implementación de estos cambios tan complejos. Se elaboró un marco adaptado del sistema sanitario, que se guía por los conceptos y las definiciones de la Organización Mundial de la Salud, para tener una idea del alcance de las reformas sanitarias en los primeros 10 años de la constitución. En este contexto, se aplicó el marco para documentar las leyes sanitarias y los organismos públicos ya promulgados y en curso, en el que se comparó el grado de transformación antes y después de la Constitución de 2010. El análisis realizado reveló que se habían formado múltiples estructuras (leyes y organismos públicos de ejecución) en todo el sistema sanitario, que tenían muchas estructuras de gestión nuevas alineadas con la transmisión, pero que estaban fragmentadas dentro de la subfunción de reglamentación. Al desestructurar las funciones normativas del sistema sanitario, el marco permitió realizar un mapeo completo de los diversos atributos del sistema sanitario (funciones, leyes y organismos de ejecución). Se considera que el marco que se propone aquí es un instrumento útil para los países que quieren elaborar e implementar un fundamento jurídico propicio para la cobertura sanitaria universal. La reforma constitucional es una fuerza de movilización que permite obtener importantes avances en el cambio institucional del sector sanitario, lo que fomenta dos aspectos de la viabilidad del cambio: la aceptación de las partes interesadas y la autoridad para proceder.

Integrated Cross-Sectional Multiplex Serosurveillance of IgG Antibody Responses to Parasitic Diseases and Vaccines in Coastal Kenya.

Accurate and cost-effective identification of areas where co-endemic infections occur would enable public health managers to identify opportunities for implementation of integrated control programs. Dried blood spots collected during cross-sectional lymphatic filariasis surveys in coastal Kenya were used for exploratory integrated detection of IgG antibodies against antigens from several parasitic infections (Wuchereria bancrofti, Schistosoma mansoni, Plasmodium spp., Ascaris lumbricoides, and Strongyloides stercoralis) as well as for detection of responses to immunizing agents used against vaccine-preventable diseases (VPDs) (measles, diphtheria, and tetanus) using a multiplex bead assay (MBA) platform. High heterogeneity was observed in antibody responses by pathogen and antigen across the sentinel sites. Antibody seroprevalence against filarial antigens were generally higher in Ndau Island (P < 0.0001), which also had the highest prevalence of filarial antigenemia compared with other communities. Antibody responses to the Plasmodium species antigens circumsporozoite protein (CSP) and merozoite surface protein-1 (MSP-1)19 were higher in Kilifi and Kwale counties, with Jaribuni community showing higher overall mean seroprevalence (P < 0.0001). Kimorigo community in Taita-Taveta County was the only area where antibody responses against S. mansoni Sm25 recombinant antigen were detected. Seroprevalence rates to Strongyloides antigen NIE ranged between 3% and 26%, and there was high heterogeneity in immune responses against an Ascaris antigen among the study communities. Differences were observed between communities in terms of seroprevalence to VPDs. Seroprotection to tetanus was generally lower in Kwale County than in other counties. This study has demonstrated that MBA holds promise for rapid integrated monitoring of trends of infections of public health importance in endemic areas.

Assessment of lymphatic filariasis prior to re-starting mass drug administration campaigns in coastal Kenya.

BACKGROUND: Lymphatic filariasis (LF) is a debilitating disease associated with extensive disfigurement and is one of a diverse group of diseases referred to as neglected tropical diseases (NTDs) which mainly occur among the poorest populations. In line with global recommendations to eliminate LF, Kenya launched its LF elimination programme in 2002 with the aim to implement annual mass drug administration (MDA) in order to interrupt LF transmission. However, the programme faced financial and administrative challenges over the years such that sustained annual MDA was not possible. Recently, there has been renewed interest to eliminate LF and the Kenyan Ministry of Health, through support from World Health Organization (WHO), restarted annual MDA in 2015. The objective of this study was to evaluate the current status of LF infection in the endemic coastal region of Kenya before MDA campaigns were restarted. RESULTS: Ten sentinel sites in Kwale, Kilifi, Tana River, Lamu, and Taita-Taveta counties in coastal Kenya were selected for participation in a cross-sectional survey of LF infection prevalence. At least 300 individuals in each sentinel village were sampled through random house-to-house visits. During the day, the point-of-care immunochromatographic test (ICT) was used to detect the presence of Wuchereria bancrofti circulating filarial antigen in finger prick blood samples collected from residents of the selected sentinel villages. Those individuals who tested positive with the ICT test were requested to provide a night-time blood sample for microfilariae (MF) examination. The overall prevalence of filarial antigenaemia was 1.3% (95% CI: 0.9-1.8%). Ndau Island in Lamu County had the highest prevalence (6.3%; 95% CI: 4.1-9.7%), whereas sites in Kilifi and Kwale counties had prevalences < 1.7%. Mean microfilarial density was also higher in Ndau Island (234 MF/ml) compared to sentinel sites in Kwale and Kilifi counties (< 25 MF/ml). No LF infection was detected in Tana River and Taita-Taveta counties. Overall, more than 88% of the study participants reported to have used a bed net the previous night. CONCLUSIONS: Prevalence of LF infection is generally very low in coastal Kenya, but there remain areas that require further rounds of MDA if the disease is to be eliminated as a public health problem in line with the ongoing global elimination efforts. However, areas where there was no evidence of LF transmission should be considered for WHO-recommended transmission assessment surveys in view of stopping MDA.

Health financing reform in Kenya - assessing the social health insurance proposal.

Kenya has had a history of health financing policy changes since its independence in 1963. Recently, significant preparatory work was done on a new Social Health Insurance Law that, if accepted, would lead to universal health coverage in Kenya after a transition period. Questions of economic feasibility and political acceptability continue to be discussed, with stakeholders voicing concerns on design features of the new proposal submitted to the Kenyan parliament in 2004. For economic, social, political and organisational reasons a transition period will be necessary, which is likely to last more than a decade. However, important objectives such as access to health care and avoiding impoverishment due to direct health care payments should be recognised from the start so that steady progress towards effective universal coverage can be planned and achieved.

Typhoid is over-reported in Embu and Nairobi, Kenya.

The paper looks at the usefulness of the Widal agglutination test in the context of variable normal antibody titres in two different populations in Kenya, and in comparison to the blood culture method of diagnosis. It presents a prospective case-control study. We examined 846 blood cultures and an equal number of serum samples, and 782 stools from adults who presented at two study sites; Kenyatta National Hospital and one hospital and 3 clinics in Embu District, with symptoms similar to typhoid. Examined also were 360 serum samples and stools from adults who were apparently healthy (controls) who sought routine medical examination at the study sites. From blood cultures, isolation rates for typhoid for Embu (3% ) and Nairobi (2.2%) were not significantly different (p>0.01). In addition the control population from the two study sites did not show any significant background O antibody titre levels characteristic of typhoid endemic areas. All the 7 commonly available Widal test kits including Murex, Europath, Biotech, Humatex, Biosystems, Microsystems and Typhex, that were evaluated for efficacy were equally specific in diagnosis of typhoid by Widal agglutination methods. However, there were minor differences in the sensitivities of the kits. The Widal test method gave a lower sensitivity (81.3%) than specificity (93%) when compared to the culture of blood for diagnosis of typhoid. Going by the reports of typhoid outbreaks in Embu and Nairobi (ca. 20-25% reported prevalence) we conclude that there has been over-reporting probably due to poor methodologies of performing the Widal test. We recommend adequate clinical examination in suspected cases of typhoid in addition to proper Widal in order to improve typhoid diagnosis. Newer improved methods that are more specific and sensitive than the Widal test need to be evaluated in improving laboratory diagnosis of typhoid.
