ABSTRACT
BACKGROUND: The main elements of effective vaccine cold chain management at the immunization service delivery point are well-trained vaccine cold chain handlers, vaccine storage equipment, and appropriate vaccine management procedures. Vaccine cold chain handlers must have enough expertise to provide the correct vaccine at the right time, maintain vaccine potency, and minimize vaccination failures. The study assessed knowledge of vaccine cold chain handlers on vaccine cold chain management, adherence to the WHO vaccine storage codes and vaccine cold chain management practice at primary health facilities in Dalocha district of Silt'e zone. METHOD: Institutional-based cross-sectional study was done at twenty-eight primary health facilities. One hundred forty primary health workers were drawn from four health centers and twenty-four health posts operating in Dalocha woreda of Silt'e zone, SNNPR, Ethiopia. A self-administered questionnaires and on-spot observation checklists were adapted from the WHO and WHO-UNICEF-effective vaccine management assessment tools to collect data from cold chain unit of the primary healthcare facilities. Data were entered to EPI data version 3.1; exported and analyzed using SPSS version 22. Statistical analysis was carried out to determine the level of knowledge, adherence to WHO cold chain management guideline and vaccine handling practice. The relationship that the knowledge of primary healthcare workers, primary healthcare workers training status, primary healthcare facilities' adherence to WHO vaccine storage codes, and length of work experience of primary health care workers have with the vaccine management practice were also explored RESULT: Above Half (54%) of the respondents have satisfactory knowledge of vaccine cold chain management. One hundred (71.4%) vaccine cold chain handlers did point correctly to the recommended range of temperature (2°C -8°C) for vaccine storage. Around two-thirds (63.6%) of them were aware of the twice-daily temperature recordings. Nearly half, (46.2%) of primary healthcare facilities have experienced poor adherence to the WHO storage practice codes. Around three-fifths of the observed primary healthcare facilities have registered undesirable vaccine management practices. The primary healthcare workers who received training on vaccine cold chain management (χ2 = 0.058, p=0.015), served at primary health care facilities for more five years (χ2 =18.545, p≤0.001), shown good adherence to WHO vaccine storage code (χ2 =18.545, p≤0.001), have sufficient knowledge on vaccine cold chain management (χ2=4.210, p≤0.031) were all significantly associated with desirable vaccine cold chain management practice. CONCLUSION: There is a gap in vaccine cold chain handlers' knowledge about vaccine cold chain management and less than desirable adherence to WHO vaccine storage codes at primary healthcare facilities in Dalocha district. The majority of the observed primary health facilities have registered poor vaccine management practices. Everyone who has a stake in the cold chain management of vaccines should do their share, individually and collectively, to guarantee that everyone reaps the benefits of an effective cold chain.
ABSTRACT
BACKGROUND: Regarding the protection of community and health professionals suffering from a COVID-19 outbreak, currently different alcohol-based hand sanitizers have been distributed. Even though for effective protection effective alcohol-based hand sanitizers are mandatory. Their efficacy was not evaluated. This is the reason why this research was designed to assess the antimicrobial efficacy of hand sanitizers that have been sold in southern parts of Ethiopia. METHODS: Six test organisms (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhimurium and Shigella boydii) were selected from different clinical specimens. Then seven locally made products of alcohol-based hand sanitizers (MTU, Folium Fine, Epharm, Harego, Taflen and Sheba) were purchased and the disc diffusion, minimum inhibition concentration and minimum bactericidal concentration test were done against selected test organisms. Quality control measures throughout the whole process of the laboratory work were implemented and descriptive parameters were analyzed. RESULTS: The zones of inhibition of the hand sanitizers at their claim concentration were ranged from noninhibition zone (Folium) to 27mm (Sheba). The minimum inhibitory concentration against all selected test organisms was observed at 45%, 55%, 65% and Taflen on undiluted form. The growth of test organisms was decreased across increasing the concentration gradient of different hand sanitizers. MTU except against E. coli, Fine, Hargo, Ephra and Sheba hand sanitizers were showed growth below 60% concentrations for all test micro-organisms. But a Folium product against all selected test micro-organisms and MTU product against E. coli were not bactericidal. CONCLUSION: Fine, Hargo, Ephra, Sheba and Taflen sanitizers were the products that were effective in inhibiting the growth of all the selected test organisms, and they were having effective bactericidal activity in vitro at their claim concentration. But MTU product against E. coli and Folium product against all test microorganisms were not having an effective bactericidal activity. So, regulatory authorities and manufacturers should implement strict quality control measures and regular observations throughout the production to ensure the efficacy of hand sanitizers.
ABSTRACT
BACKGROUND: Coronaviruses are a large group of viruses that are common throughout the community. They are associated with mortality, hospitalization, substantial extra costs and lower patient's quality of life. Thus, this study aimed to assess the community's knowledge of COVID-19 and associated factors in Mizan-Aman town, southwest Ethiopia. METHODS: Community-based cross-sectional study design was conducted among the community of Mizan-Aman from April 14 to May 14, 2020. A systematic sampling technique was used to collect data from selected households. Data were entered into Epi data version 4.0.2.101 and then exported to SPSS version 24.0 for analysis. To identify the predictors of knowledge of COVID-19, multiple backward logistic regression analysis was used. To show the accuracy of data analysis, 95% CI was used, and statistical significance was considered at p <0.05. RESULTS: From 423 sampled population, 393 (92.9%) of them responded to the questionnaire. Of these, 233 (59.3%) were male, 225 (57.3%) were 18-34 years old, and 250 (63.6%) were married. The overall correct rate of the knowledge questionnaire was 74.75%. More than 85% of respondents were well aware of the main clinical symptoms of COVID-19, its transmission by close contact, its prevention by not going to crowded places and isolation of infected persons. Male gender (AOR=3.74, CI: 1.87-7.49), age (35-54 years) (AOR=3.81, CI: 1.35-10.70), age ≥55 (AOR=2.97, CI: 1.16-7.62), lack of formal education (AOR=6.0, CI: 1.54-23.40), farmer (AOR=8.72, CI: 2.08-35.53), daily laborer (AOR=7.57, CI: 2.28-25.15), merchant (AOR=6.34, CI: 2.06-19.43), house wife (AOR=11.59, CI: 2.91-46.23) were significantly associated with poor knowledge, whereas single marital status was less likely associated with poor knowledge of COVID-19. CONCLUSION: One-third of the study participants had poor knowledge regarding COVID-19. Male gender, age above thirty-five years, lack of formal education, being farmer, daily laborer, merchant and house wife were significantly associated with poor knowledge. Therefore, awareness creation should be given.
