Rotavirus vaccination has resulted in a notable decline in hospital admissions for rotavirus infections in a rural resource-limited population in Kenya. This provides early evidence for continued use of rotavirus vaccines in routine childhood immunisations in Kenya. Our data also underscore the need for expanding coverage on second dose so as to maximise the impact of the vaccine.

Louse-borne relapsing fever (LBRF) is endemic in Ethiopia. The epidemiological and clinical aspects of LBRF and the differences between the infection in children and that in adults were investigated in a rural hospital in Ethiopia. During the 5-year study (1997-2002), 197 patients had a confirmed diagnosis of LBRF. Most (62.1%) of the cases were children under 15 years of age. The adult cases (i.e. those aged > or =15 years) were far more likely to present with headache (76.9% v. 40%; P <0.001), musculo-skeletal pains (61.5% v. 30.5%; P <0.001), dizziness (64% v. 39%; P =0.002) and bleeding (16.9% v. 3.8%; P =0.005) than the paediatric. The overall level of case fatality was 6.4%. Death appeared to be significantly associated with adulthood (P =0.01), delay in consultation (P =0.026) and the presence of vomiting (P =0.023). LBRF is clearly still a public-health problem in Ethiopia, where the clinical manifestations of the disease differ according to the age of the case.

Pathogens handled in a Biosafety Level 3 (BSL-3) containment laboratory pose significant risks to laboratory staff and the environment. It is therefore necessary to develop competency and proficiency among laboratory workers and to promote appropriate behavior and practices that enhance safety through biosafety training. Following the installation of our BSL-3 laboratory at the Center for Microbiology Research-Kenya Medical Research Institute in 2006, a biosafety training program was developed to provide training on BSL-3 safety practices and procedures. The training program was developed based on World Health Organization specifications, with adjustments to fit our research activities and biosafety needs. The program is composed of three phases, namely initial assessment, a training phase including theory and a practicum, and a final assessment. This article reports the content of our training program.

The NUITM-KEMRI biosafety training program was developed for capacity building of new biosafety level three (BSL-3) laboratory users. The training program comprehensively covers biosafety and biosecurity theory and practice. Its training curriculum is based on the WHO biosafety guidelines, local biosafety standards, and ongoing biosafety level three research activities in the facility, also taking into consideration the emerging public health issues. The program’s training approach enhances the participant’s biosafety and biosecurity knowledge and builds their skills through the hands-on practice sessions and mentorship training. Subsequently, the trainees are able to integrate acquired knowledge and good practices into their routine laboratory procedures. This article describes implementation of the NUITM-KEMRI biosafety training program.

When properly used and adequately maintained, a biological safety cabinet (BSC) provides protection to the laboratory worker, the products, and the environment. Knowledge about proper use of the BSC is therefore important. This study evaluated BSC usage knowledge and practices and the effect of prior experience on training outcomes. Thirteen participants randomly selected from research centers were evaluated through a structured questionnaire covering biosafety considerations involved in using a BSC as per the World Health Organization's Laboratory Biosafety Manual, third edition. The questionnaire was administered before and after the training. Training was conducted using the NUITM-KEMRI biosafety training program, enhanced to include more modules on BSCs. Differences in the participants' knowledge and practices regarding BSC usage were observed. After training, the participants were able to give correct responses. Furthermore, participants who had fewer years of experience showed the greatest improvement. Results indicate the need for proper training of laboratory workers early in their careers, coupled with close supervision, mentorship, and regular refresher training.

A biocontainment facility is a core component in any research setting due to the services it renders towards comprehensive biosafety observance. The NUITM-KEMRI P3 facility was set up in 2007 and has been actively in use since 2010 by researchers from this and other institutions. A number of hazardous agents have been handled in the laboratory among them MDR-TB and yellow fever viruses. The laboratory has the general physical and operational features of a P3 laboratory in addition to a number of unique features, among them the water-air filtration system, the eco-mode operation feature and automation of the pressure system that make the facility more efficient. It is equipped with biosafety and emergency response equipments alongside common laboratory equipments, maintained regularly using daily, monthly and yearly routines. Security and safety is strictly observed within the facility, enhanced by restricted entry, strict documentation and use of safety symbols. Training is also engrained within the operation of the laboratory and is undertaken and evaluated annually. Though the laboratory is in the process of obtaining accreditation, it is fully certified courtesy of the manufactures' and constructed within specified standards.

Kenya is a country where cholera is endemic; it has experienced three substantial epidemics over the past few decades, but there are limited data on the drug resistance patterns of V. cholerae at the national level. To the best of our knowledge, this is the first study to investigate the antimicrobial susceptibility profiles of V. cholerae O1 strains isolated from two consecutive epidemics and to examine their associated antimicrobial genetic determinants.
