No full textBackground:Home based HIV testing and counseling (HBTC) increases access to services and is associated with high testing uptake. Alongside testing, individuals are offered HIV prevention messages with an aim of helping them reduce HIV high risk sexual behaviors. This study explored the level of provision and subsequent utilization of HIV prevention messages and associated change in behavior among individuals who had received HBTC previously in an informal settlement.Methods:In a mixed method cross sectional study, we interviewed 1257 individuals and conducted 6 focus group discussions (FGD). Multiple correspondence analysis (MCA) was used to construct provision of prevention messages and behavior change indices using STATA 3.0. Pearson\u2019s chi\u2013square statistics was used to test for bivariate association between the outcomes and logistic regression analysis was carried out with the behavior change index as the outcome of interest and the predictors considered significant (p<0.1). Thematic content analysis for qualitative data was done using Atlas 3.0.Results:Out of the 1257participants, 1078 (85.8%) had ever tested for HIV, with 74.2% having tested in the Kibera HBTC program. Nearly all (97.4%) rated HBTC experience as either excellent (62.4%) or good (37%) and would recommend it to a friend. Provision of prevention messages was high among HBTC clients compared to clients from other testing sites; partner reduction counselling (64% versus 52%) and faithfulness (78.3% versus 67%); p=0.001. Self\u2013reported behavior change after HBTC was generally low with condom use at 10.7% and men more likely to practice safer sex (p = 0.002). Trust of the sexual partners and fear of suspicion were the main reasons given for not using condoms. Clients testing HIV positive after previous negative result were 3.4%. The focus group discussions reported multiple sexual partnerships among both HIV negative and positive residents alike.Conclusion:Although prevention messages delivered during HBTC are accepted and appreciated in this community, their utilization is low in both HIV negative and positive individuals. Innovative strategies for change of normative beliefs about sexual behavior are urgently needed.U19 GH000041/GH/CGH CDC HHS/United State

No full textLaboratories are integral to the delivery of quality health care and for public health functions; however laboratory systems and services are often neglected in resource-poor settings such as the East African region. In order to sustainably strengthen national laboratory systems in resource-poor countries, there is a need to train laboratory personnel to work in clinical as well as public health laboratories. In 2004,Kenya, Uganda, Tanzania, and South Sudan began training public health laboratory workers jointly with field epidemiologists in the Kenya Field Epidemiology and Laboratory Training Program (FELTP), and later through the Tanzania FELTP, as a strategy to strengthen public health laboratories. These programs train laboratory epidemiologists through a two-year public health leadership development course, and also offer various types of short course training for frontline staff. The FELTP laboratory graduates in Kenya, Tanzania, Uganda, and South Sudan are working in their respective countries to strengthen public health laboratory systems while the short course participants provide a pool of frontline implementers with the capacity to support the lower tiers of health systems, as well as serve as surge capacity for the regions and the national level. Through training competent public health laboratory workers, the East African ministries of health, in collaboration with other regional partners and stakeholders are now engaged in developing and implementing a holistic approach that will guarantee an overall strengthening of the health system by using well-trained public health laboratory leaders to drive the process. Strengthening public health laboratory medicine in East Africa is critical to improve health-care systems. The experience with the FELTP model in East Africa is a step in the right direction towards ensuring a stronger role for the laboratory in public health.201122359702PMC3266675665

No full textBackground: Road traffic injuries continue to exert a huge burden on the health care system in Kenya. Few studies on the severity of road traffic injuries have been conducted in Kenya. We carried out a cross-sectional study to determine factors associated with severity of road traffic injuries in a public hospital in Thika district, Kenya. Methods: Road crash victims attending the Thika district hospital, a 265-bed public hospital, emergency room were recruited consecutively between 10th August 2009 and 15th November 2009. Epidemiologic and clinical information was collected from medical charts and through interview with the victims or surrogates using a semi-structured questionnaire. Injuries were graded as severe or non-severe based on the Injury Severity Score (ISS). Independent factors associated with injury severity were assessed using multivariate logistic regression. Results: The mean age of participants was 32.4 years, three quarters were between 20-49 years-old and 73% (219) were male. Nineteen percent (56/300) of the victims had severe injury. Five percent (15) had head injury while 38% (115) had fractures. Vulnerable road users (pedestrians and two-wheel users) comprised 33% (99/300) of the victims. Vulnerable road users (OR=2.0, 95%CI=1.0-3.9), road crashes in rainy weather (OR=2.9, 95%CI=1.3-6.5) and night time crashes (OR=2.0, 95%CI=-1.1-3.9) were independent risk factors for sustaining severe injury. Conclusion: Severe injury was associated with vulnerable road users, rainy weather and night time crashes. Interventions and measures such as use of reflective jackets and helmets by two wheel users and enhanced road visibility could help reduce the severity of road traffic injuries
A microsporidian impairs Plasmodium falciparum transmission in Anopheles arabiensis mosquitoes
No full textA possible malaria control approach involves the dissemination in mosquitoes of inherited symbiotic microbes to block Plasmodium transmission. However, in the Anopheles gambiae complex, the primary African vectors of malaria, there are limited reports of inherited symbionts that impair transmission. We show that a vertically transmitted microsporidian symbiont (Microsporidia MB) in the An. gambiae complex can impair Plasmodium transmission. Microsporidia MB is present at moderate prevalence in geographically dispersed populations of An. arabiensis in Kenya, localized to the mosquito midgut and ovaries, and is not associated with significant reductions in adult host fecundity or survival. Field-collected Microsporidia MB infected An. arabiensis tested negative for P. falciparum gametocytes and, on experimental infection with P. falciparum, sporozoites aren’t detected in Microsporidia MB infected mosquitoes. As a microbe that impairs Plasmodium transmission that is non-virulent and vertically transmitted, Microsporidia MB could be investigated as a strategy to limit malaria transmission
Balanced scorecard as an effective strategy implementation tool by the Nairobi City County government in Kenya
No full textThe purpose of this study was to investigate effectiveness of balanced scorecard as
applied in strategy implementation at the Nairobi City County government in Kenya.
The study sought to find out if practices adopted by Nairobi City County government
were in conformity with balanced scorecard best practices for nonprofit organizations
and governments. The aim of the study was further to find out the challenges faced by
Nairobi City County government in the use of balanced scorecard tool in strategy
implementation. The findings from this study will enrich knowledge in the field of
strategy implementation as it contributes to policy formulation and practice in county
government management. A case study at Nairobi City County government was carried
out where both primary and secondary data was obtained. Primary data was collected
using semi structured interview guide where in depth probing was employed.
Secondary data was obtained from management published reports and internet. The
data was analyzed as per the objective of the study using content analysis. The findings
from the study indicate that a number of best practices of the balanced scorecard is in
application at the Nairobi City County government during strategy implementation.
Strategic objectives of the county cascade well down to departments and individual
employees. This has been achieved through strategy framework that dissects strategic
objectives into seven key performance areas with respective key focus areas.
Appropriate measurement tools, key performance indicators, track strategy
implementation progress. The study also identified challenges of balanced scorecard
implementation and suggested solutions to address the challenges. The findings from
this study is expected to assist management at Nairobi City County government to
exercise control designing policies, training and development for future needs. Better
communications tools are expected to be employed to build consensus on strategy
throughout the entire county government. The study will too contribute to body of
knowledge of resource based and dynamic capability theories of strategic management
as resource availability and how it is organized in achievement of strategic objectives
is explored. Study findings is expected to act as benchmark for other counties from
which policies framework and practices about strategy implementation using scorecard
tool will be anchored. Other organizations may get a better understanding of balanced
scorecard as a tool of strategy implementation, its effects and challenges

No full textNairobi is considered a low-risk area for malaria transmission, but travel can influence transmission of malaria. We investigated the demographic characteristics and travel history of patients with documented fever and malaria in a study clinic in a population-based surveillance system over a 5-year period, January 1, 2007 to December 31, 2011. During the study period, 11,480 (68%) febrile patients had a microscopy test performed for malaria, of which 2,553 (22%) were positive. Malaria was detected year-round with peaks in January, May, and September. Children aged 5-14 years had the highest proportion (28%) of positive results followed by children aged 1-4 years (23%). Almost two-thirds of patients with malaria reported traveling outside Nairobi; 79% of these traveled to three counties in western Kenya. History of recent travel (i.e., in past month) was associated with malaria parasitemia (odds ratio: 10.0, 95% confidence interval: 9.0-11.0). Malaria parasitemia was frequently observed among febrile patients at a health facility in the urban slum of Kibera, Nairobi. The majority of patients had traveled to western Kenya. However, 34% reported no travel history, which raises the possibility of local malaria transmission in this densely populated, urban setting. These findings have important implications for malaria control in large Nairobi settlements
Potential health-care associated respiratory syncytial virus in three referral Hospitals in Kenya, 2009-2011
No full textBackground: Respiratory syncytial virus (RSV) is a major cause of community acquired severe respiratory illness in infants, immunocompromised individuals and the elderly. Limited information exists on the contribution of RSV in respiratory Hospital Associated Infection (rHAI) in developing countries.Objective: To characterize Respiratory Syncytial Virus in the three Kenyan referral setting as a potential contributor to respiratory hospital acquired infection.Methods: The study targeted all patients whose samples tested positive for RSV from the ongoing surveillance on healthcare associated respiratory infections. The study collected nasal and oropharyngeal samples from patients who developed new-onset axilla fever and influenza like illness, in patients who had been afebrile for at least three (3) days in the wards and tested them for different respiratory pathogens (Influenza A and B, Parainfluenza, Human metapneumovirus and adenovirus) alongside RSV. During this period A total of 37 samples tested RSV positive. These were characterized as RSV-A and -B using RT-PCR. Those that typed successfully were then sequenced in the attachment G protein and phylogenetically analyzed.Results: Of the 37 samples, 13(35%) were RSV A, 6 (16%) RSV B, 1 (3%) was AB and 17 (46%) did not type. Twenty out of the 37 attained the sequencing criteria and only seventeen gave successful sequences. Three RSV- A and 2 RSV-B sequenced samples from KNH were 100% identical in the G ectodomain sequences. One RSV-A specimen from MDH and one RSV-A positive from NNPGH had 100% identity. Three sequences from KNH clustered with high nucleotide sequence identity. Children below 2years were significantly more at risk of RSV than those aged 5years and above (aOR=0.21,p=0.012).Conclusions: The study inferred possibility of spread of RSV within the hospitals especially the paediatric ward. Any interventions to curb the spread should specifically target all children ≤ 2 years.Afr J Health Sci. 2016; 29(1):1-1

No full textTo study the association of multidrug-resistant enteroaggregative Escherichia coli with persistent diarrhea in Kenyan children, stool specimens were obtained from 862 outpatients under 5 years of age from July 1991 to June 1993. E. coli O44 was identified as the sole bacterial pathogen in four patients experiencing at least 14 days of fever, vomiting, and diarrhea. Disk diffusion testing showed E. coli O44 resistance to tetracycline, ampicillin, erythromycin, trimethoprim-sulphamethoxazole, and amoxicillin/clavulanate and sensitivity to chloramphenicol, nalidixic acid, azithromycin, and cefuroxime. Further studies are needed to clarify the epidemiology, clinical spectrum, and pathogenesis of enteroaggregative E. coli infection

Virulence determinants of diarrhoegenic <i>Escherichia coli</i> - A Mini Review
No full textDiarrhoegenic Escherichia coli are of a broad variety. A clear understanding of the virulence/pathogenicity determinants of pathogenic Escherichia coli is important as they affect a large section of the population in the tropical and developing areas of the world. Faecal contamination of food and water is the major route of infection for humans. Based on minor differences in surface structure chemistry there are over 800 serotypes of Escherichia coli. Diagnostic methods used nowadays focus on the detection of either specific toxins such as heat stable (ST), heat labile (LT) and their specific attributes for example colonization factors (CF's) and specific target genes for example eaeA, which permit the identification of the corresponding pathotype. Classification of E. coli is an evolving science and more categories of pathogenic E. coli will be identified in the future. The virulence determinants in E. coli play the major role in infections in both humans and animals. Journal of Tropical Microbiology and Biotechnology Vol. 3(1) 2007: pp. 29-3
