Health facilities can be sources of bio-hazards to healthcare personnel (HCP). Personal protective equipments (PPE) are among the key preventive control measures. The main objective of this research was to determine the efficacy of PPE as a safeguard against HBV, HCV, and HIV exposure amongst HCP at Public Primary healthcare facilities in Mombasa County. The study endeavored to assess the range and quality standards of PPEs available, adherence to PPE safety guidelines, and the rates of occupational exposures HIV, HBV, and HCV occupational exposure amongst HCP in these facilities. The research adopted a Descriptive Cross-sectional design by utilizing structured questionnaires and lab assays as data collection tools. A simple random sampling approach was used in selection of the subjects. The subjects included Clinical Officers, Lab Technicians, Nursing, Medical assistants, and Housekeepers. Laboratory assays were conducted to determine the quality standards of the PPE sampled from the facilities against KEBS standards. The findings were analyzed with the Statistical Package for the Social Sciences (SPSS), version 23.0 and presented using pie charts, contingency tables, and bar charts. This study ascertained that amongst the PPE, the uptake and compliance to gloves usage was the highest at 93.3%. There was significant association between range of PPE and utilization of available protective gear [X2 (DF= 1, N= 149) = 0.017, p= 0.05]. Quality standard analysis results established that the gloves met the accepted quality levels. 69%were exposed to blood and OPIM, Sharp related injuries were the highest reported mode of exposure at 44.7%, 70.4% of the exposed had access to hands protection [X2 (DF= 1, N= 103) = 0.548, p= 0.05]. PPE are not effective as apparatus but are effective when implemented as a policy whereby adequate supply, quality standards, adherence to usage and guidelines are critical to the success of the program.

The informal (Juakali) sector in Kenya lack occupational health and safety services and workers unknowingly exposed to health hazards. Worldwide, occupational noise is a significant cause of adult onset-hearing loss and 16% of disabling hearing loss in adults. . The aim of the study was to identify the health effects of noise to the Juakali artisans in King'orani area by identifying key sources of noise, assessing hearing threshold levels, examining auditory health effects of noise and the prevalence of noise induced hearing loss. This was through administration of a structured questionnaire, noise level measurements, and pure tone eudiometry to stratified, randomly selected subjects. Data was coded cleaned and analyzed using SPSS version 21.0. Out of 124 participants involved in the study, prevalence of NIHL was 59.7% with 31.5% having mild, 18.5% moderate, and 5.7% had severe, and 4% had profound impairments. The level of impairment increased with the duration and level of exposure to noise above 90 dB. Those involved in operation of pneumatic tools were the most affected compared to those involved in other activities as food vendors and hawkers. Exposure level and duration was greatly associated with auditory effects such as Tinnitus, headache, poor concentration, and sleep disorders. In conclusion NIHL, headaches, tinnitus, poor concentration and sleep disturbances are related to prolonged exposure to high level of noise above 90dB with a positive correlation coefficient of 0.248 at p<0.05. Therefore, review of OSHA 2007 to effectively regulate the informal sector, awareness campaign on effects of noise exposure, establishment of Hearing monitoring canters, special subsidies and provision of PPEs will be able to arrest the otherwise forgotten irreversible disability causing Hazard the Juakali artisans are exposed to.

Water faces an endemic global shortage due to natural replenishment, melting of glaciers and receding in snowlines. This impact is visible as seventy rivers have stopped flowing into the sea; aquifers are depleting and the world’s thirst for water is likely to become one of the most pressing issues of the 21st century. Rapid pace of industrialization, concurrent growth of urbanization, and change of life style of ever expanding population have the potential to damage the environment and degrade the quality of water resources. Since there has been growing concern about pollution in Angul-Talcher area due to industrial, mining and other anthropogenic activities, Central Pollution Control Board and Ministry of Environment & Forests have identified this zone as one of the hot spots in respect of pollution hazards. The present study is an attempt to provide a qualitative and quantitative status indicating the suitability of water resources for drinking purpose. The study on seasonal variations of physico-chemical characteristics along with its water quality of surface water resources fluctuated from one season to other thus making the sources unfit for human consumption. Water Quality Index (WQI) values for surface water in different seasons has been calculated to classify the sources according to pollution level and suitability for drinking purposes.

Immunization is an important public health intervention aimed at reducing child mortality and morbidity in line with the fourth goal of the Millennium Development Goals. It is an important means for controlling six vaccine-preventable diseases, namely, Tuberculosis, Diphtheria, Whooping cough, Tetanus, Polio, and Measles. World Health Organization recommends that all children should receive full immunization by the age of two years to boost their immunity. Although immunization coverage has improved significantly over the past four decades, about one-fifth of the world?s children still fail to receive full doses of the standard antigens, majority of who are natives of the African region. In Somalia, empirical studies on immunization coverage do not provide detailed information about immunization coverage and key determinants at the community level and within specific groups such as pastoralists. The main objective of this study was to determine barriers to full immunization coverage among under-five years children within Benadir region. The study applied a cross-sectional survey design, with both quantitative and qualitative methods. Primary data will was sourced from under-five children, service providers in selected health facilities, public health officers and community health workers. A mixture of probability and non-probability sampling procedures were applied to select participants in each category. Fisher?s formula for sample size determination from large populations will be used to select a representative sample of the under five years children. The study applied a survey questionnaire with both closed and open-ended questions, as well as Focus Group Discussion and Key Informant Interview guides. Both quantitative and qualitative approaches were applied to process, analyze, and interpret the data.
