ABSTRACT Background: Mycobacterium Tuberculosis commonly referred to as (TB) is still one of the major health concerns, with high prevalence globally as well as in Namibia. While significant progress has been achieved in the prevention and treatment services of TB in the country, including use of community-based service providers and community-based health workers, the number of relapse cases remained high. The study aimed at assessing the role of Community Based Service Providers in the prev...
ABSTRACT BACKGROUND Group B streptococcus (GBS) naturally colonises the lower gastrointestinal and female genitourinary tract. It poses a great risk of morbidity and mortality to infants born to colonised mothers. It is highly implicated in maternal infections such as endometritis and chorioamnionitis as well as neonatal infections such as pneumonia, meningitis and septicaemia. It also causes stillbirths and miscarriages in colonised women. Group B streptococcus infection in neonates is class...
ABSTRACT Vehicle exhaust fumes emission, as one of leading major source among smoke producing air pollutants, was examined in this study. Nairobi, a mega-city with increasingly high levels of air pollution was studied with special emphasis on one of its roads, Waiyaki Highway. Objectives were to find if there is air pollution, air pollution effects growth and stress of plants. This road was investigated to gain scientific understanding of the effects of vehicle fumes on plants. Hotspots (ICEA...

The study aimed at identifying sources of occupational stress, determining the impact of occupational stress on employee performance, as well as examining the strategies to curb occupational stress on employee performance. The research employed quantitative (Questionnaires) and qualitative (interviews) research methods. The research established that job insecurity...
ABSTRACT Land use changes, rapid population growth, poverty, climate change variability and lack of livelihoods diversification aggravate watershed degradation through inappropriate land use methods resulting to water scarcity, land and water pollution, and governance issues. Soil erosion and siltation has led to land denudation, habitat loss and farm lands losing their soil fertility and compromising food security. The main objective of the study was to find out how land use methods influenc...
ABSTRACT Global, regional and national production of Nile Tilapia (Oreochromis niloticus) has faced challenges of low yields and lack of crucial culture information. Farmers in Teso North Sub County recorded lower yields than expected in 2009 despite having been provided with inputs. Factors responsible for the low production had not been established and water quality was suspected to be among them. The purpose of this study was to assess the effects of water quality on the growth of Nile Til...
Abstract Aquatic pollution by heavy metals remains a recurrent problem globally due to their persistence, toxicity and ability to accumulate in biological systems. This study investigated the pollution trend, ecological and public health risks associated with heavy metal pollution in the Lagos Lagoon as well as pattern of interaction among heavy metals that can be exploited for remediation of exposed aquatic organisms. Heavy metal content in surface water, sediment and biota were analyzed us...
ABSTRACT The ever increasing levels of electronic waste (e-waste) and limited capacities for disposal and recycling have worsened e-waste management considering only 10% of e-waste is properly managed globally. In developed countries, e-waste management is guided by extended producer responsibility frameworks that ensure e-waste collection and recycling through consumer participation whereas, in Asia and Africa e-waste is managed through inefficient solid waste systems resulting to degradatio...

ABSTRACT The honeybee (Apis mellifera L.) produces honey and cross pollinates plants for improved socioeconomic wellbeing. However its colony populations globally and locally have been declining. In Transmara West Sub-county, hive colonization and honey yields have been low, which is due to the decline in honeybee population believed to be caused by pesticides use and pests attack. Although their relative contributions are unknown, Beekeepers suspect pesticides use hold a key role in colony p...
ABSTRACT Quarry mining produces substantial dust amounts bearing an adverse effect on human health in several ways, mainly the respiratory system. Even though employers are obligated to protect their employees from occupational hazards, the quarry mining industry in Namibia has failed to honour that obligation. This study investigated quarry workers and the surrounding community’s exposure to dust as well as their risk of getting chronic respiratory diseases in the Erongo region of Namibia....
ABSTRACT Introduction Tuberculosis and diabetes mellitus are public health challenges globally. The World Health Organization (WHO) Global report on diabetes reiterated that diabetes is a well-known risk factor for tuberculosis (TB) and that diabetes is associated with poor tuberculosis treatment outcomes, while tuberculosis is linked with deteriorating glycemic control. Namibia is among the top 30 high TB burden countries in the world (WHO, 2016) and added to that is the increasing prevalenc...
ABSTRACT This study focused on safety and health implications of food from food outlets at Nyika growth point. The purpose of the study was to evaluate safety and health hazards associated with food from food outlets. Records of the Bikita Rural District Council indicated that from 2006 to 2014, the number of food outlets increased by more than 100%. Cases of food borne illnesses increased by at least 100% according to the records of the Bikita District Hospital. A cross-sectional survey was ...
ABSTRACT Test anxiety is conceived as the hyper-arousal condition that results in physiological, emotional and intellectual changes that prevent the effective use of the previously learned information while taking an examination. It is composed of “worry” which a cognitive anxiety related with performance and “emotionality” the arousal of autonomic nervous system in evaluative situations (Morris & Liebert 1970 in Ndirangu 2009). Examination performance is the grade point or scores obt...
