Introduction: The coronavirus disease (COVID-19) infection rate and mortality among Nigerian health care workers appear to be on the increase. This study determined the level of knowledge, attitude, practices, and impact of COVID-19 infection on healthcare workers (HCWs) working in a South-Eastern Nigerian state.
Methodology: This was a web-based, cross-sectional study conducted among healthcare workers in South-eastern, Nigeria during the lockdown period. Socio-demographic profile, knowledge of COVID-19, fears and impact concerning COVID-19, attitude of health workers to work, preventive practices during this pandemic period were obtained. Data were analysed using STATA 16.0. Chi-square and Fisher’s exact tests of association were used to determine the association between variables, with the significance level set at p < 0.05.
Results: A total of 403 health care workers participated in the study. Majority of participants (n = 357, 88.59%) had good knowledge and good preventive practices (n = 328, 81.39%) of COVID-19. A significant proportion of respondents had a poor attitude to work (n = 101, 25.06%) and an attitude of indifference (n = 233, 57.82%). Almost half (48.64%) of participants had been negatively affected by COVID-19. Knowledge significantly influenced practice (p = 0.029). Lack of Personal protective equipment, fear of dying and going to common places, had a significant impact on the attitude of workers.
Conclusion: Good knowledge which influenced practice, high use of preventive practices, with associated poor and indifferent attitude was noted among healthcare workers. Fear of death and lack of personal protective equipment had a strong impact on attitude. Female HCWs had poorer attitude to work than males.
This study highlights the need for an effective nutrition program targeted at school children in urban slums surrounded by factors predisposing them to undernutrition.
Background:Given the rising incidence of noncommunicable diseases (NCDs) globally, especially bronchial asthma, there is the need to reduce the associated morbidity and mortality by adopting an objective means of diagnosis and monitoring.Aim:This article aims to review the trends and challenges in the use of spirometry for managing childhood bronchial asthma especially in developing countries.Methods:We conducted a literature search of published data on the use of spirometry for the diagnosis of childhood bronchial asthma with special emphasis resource-poor countries.Results:Guidelines for the diagnosis and treatment of childhood asthma recommend the use of spirometry, but this is currently underused in both tertiary and primary care settings especially in developing countries. Lack of spirometers and proper training in their use and interpretation of findings as well as a dearth of asthma guidelines remains core to the underuse of spirometry in managing children with asthma. Targeting education of health care staff was, however, observed to improve its utility, and practical implementable strategies are highlighted.Conclusions:Spirometry is not frequently used for asthma diagnosis in pediatric practice especially in resource-poor countries where the NCD burden is higher. Strategies to overcome the obstacles are implementable and can make a difference in reducing the burden of NCD.
Infectious diseases remain a menace in our environment with the eventual outcome worsened by late presentation to an appropriate health facility. There is an urgent need to create public awareness on the need to seek prompt medical attention for sick children.
Background
Currently, there is a paucity of data on the knowledge and practice of preventive measures for Hepatitis E infection in Nigerian populations. This study provided data on the prevalence, knowledge and practices of prevention in an adolescent population from Nigeria.
Methods
This cross-sectional study was conducted over 3 months among rural Nigerian secondary school adolescents. An interviewer-based questionnaire was used to collect data on sociodemographic profile, knowledge, and practice of preventive measures for Hepatitis E infection. Blood samples collected from participants were analysed for Hepatitis E IgG using Elisa Kits (Sigma Diagnostics, USA). Data were analysed using SPSS software version 20.0. Tests of association were done with a level of significance set at 5%.
Results
A total of 9 out of the 414 participants tested positive for Hepatitis E IgG antibodies giving a prevalence of 2.2%. Significant factors for Hepatitis E infection were male gender {P = 0.004} and school {P < 0.001, however logistic regression gave infinite value. Most participants (98.6%) had poor knowledge of Hepatitis E infection, 239(57.7%) had good preventive practices, while 175(42.3%) had average preventive practices.
Conclusion
A low prevalence of HEV infection was recorded among study participants. There was poor knowledge of Hepatitis E, and association could not be established between HEV infection and individual preventive practices.
Air pollution is a major global public health issue causing considerable morbidity and mortality. Measuring levels of air pollutants and facilitating access to the data has been identified as a pathway to raise awareness and initiate dialogue between relevant stakeholders. Low-and middle-income countries (LMICs) urgently need simple, low-cost approaches to generate such data, especially in settings with no or unreliable data. We established a network of easy-to-use low-cost air quality sensors (PurpleAir-II-SD) to monitor fine particulate matter (PM2.5) concentrations at 15 sites, in 11 cities across eight sub-Saharan Africa (sSA) countries between February 2020 and January 2021. Annual PM2.5 concentrations, seasonal and temporal variability were determined. Time trends were modelled using harmonic regression. Annual PM2.5 concentrations ranged between 10 and 116 µg/m3 across study sites, exceeding the current WHO annual mean guideline level of 5 µg/m3. The largest degree of seasonal variation was seen in Nigeria, where seven sites showed higher PM2.5 levels during the dry than during the wet season. Other countries with less pronounced dry/wet season variations were Benin (20 µg/m3 versus 5 µg/m3), Uganda (50 µg/m3 versus 45 µg/m3), Sukuta (Gambia) (20 µg/m3 versus 15 µg/m3) and Kenya (30 µg/m3 versus 25 µg/m3). Diurnal variation was observed across all sites, with two daily PM2.5 peaks at about 06:00 and 18:00 local time. We identified high levels of air pollution in the 11 African cities included in this study. This calls for effective control measures to protect the health of African urban populations. The PM2.5 peaks around ‘rush hour’ suggest traffic-related emissions should be a particular area for attention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
