A cross-sectional study on coping strategies of frontline healthcare workers amid the COVID-19 pandemic in a developing country.

Frontline healthcare workers encountered a heightened susceptibility to negative psychological symptoms and behavioral shifts in light of the coronavirus disease 2019 pandemic. This study determined the coping strategies adopted by frontline healthcare workers in Ghana as well as assessed any differences based on demographics, job title, and ranking in four coronavirus disease 2019-designated centers in the Greater Accra region of Ghana. Using a hospital-based, mixed-method approach, the study was conducted between May 2021 and September 2021. A total of 94 frontline healthcare workers were randomly sampled and given a self-administered questionnaire, while 13 healthcare workers took in-depth interviews. Data from the survey were analyzed using both IBM SPSS and IBM AMOS and the interview data were transcribed verbatim and coded using thematic analysis. The study revealed that coronavirus disease 2019 has affected the psycho-social life of frontline healthcare workers mainly in the form of depression, anxiety, and stress. The three main coping strategies adopted by frontline healthcare workers include personal preventative measures (most dominant), seeking external expert support, and obtaining institutional support. While healthcare workers within the age group 30-39 years were found most compliant with the adoption of personal preventive measures and those below 30 years were found least compliant. This study concludes that frontline healthcare workers have been affected by a considerable level of anxiety, stress, and depression during the coronavirus disease 2019 pandemic. The study recommends a robust psychological support system at various levels of health care and an Employee Assistance Program with access to a 24-h hotline counseling service for frontline healthcare workers, continuous personal protective equipment provision, regular evidence-based updates on the management of coronavirus disease 2019 patients, and increased commitment from the government in addressing the medical needs of infected frontline healthcare workers.

Integrative Effects between a Bubble and Seal Program and Workers’ Compliance to Health Advice on Successful COVID-19 Transmission Control in a Factory in Southern Thailand

Applying health measures to prevent COVID-19 transmission caused disruption of businesses. A practical plan to balance public health and business sustainability during the pandemic was needed. Herein, we describe a "Bubble and Seal" (B&S) program implemented in a frozen seafood factory in southern Thailand. We enrolled 1539 workers who lived in the factory dormitories. First, the workers who had a high fatality risk were triaged by RT-PCR tests, quarantined and treated if they had COVID-19. Newly diagnosed or suspected COVID-19 workers underwent the same practices. The non-quarantined workers were regulated to work and live in their groups without contact across the groups. Workers' personal hygiene and preventive measures were strongly stressed. Between the 6th and 9th weeks of the program, the post-COVID-19 infection status (PCIS) of all participants was evaluated by mass COVID-19 antibody or RT-PCR tests. Finally, 91.8% of the workers showed positive PCIS, which was above the number required for program exit. Although no workers had received a vaccination, there was only one case of severe COVID-19 pneumonia, and no evidence of COVID-19 spreading to the surrounding communities. Implementation of the B&S program and workers' adherence to health advice was the key to this success.

Clinical and Epidemiological Manifestations of Ixodic Tick-Borne Borreliosis Foci in the Tomsk region

Relevance. According to official data, in 2020 in Russia, Ixodic tick-borne borreliosis took the leading position in the prevalence and registration frequency among tick-borne infections, which amounted to 38.5% of all cases of natural focal transmissible infections. In the Tomsk region for many years, the average long-term incidence of Ixodic tick-borne borreliosis exceeds the Russian one by more than 3 times. Aim. Identify features the features of the clinical and epidemiological manifestations of the Ixodic tick borne borreliosis foci in the Tomsk region; to identify priority areas for carrying out problem-oriented research in the field of ecology, epidemiology and the clinic of borreliosis infection in the Tomsk region. Materials and methods. The material for the study was the data of the federal statistical observation form «Information on infectious and parasitic morbidity» for the 2015-2020. The materials of 713 cases of Ixodic tick-borne borreliosis disease and more than 125 thousand appeals to medical organizations of the region regarding the tick bites, registered in official registration forms, were studied. As part of the annual epidemiological monitoring for a six-year period, 1200 specimens of Ixodid ticks collected in natural biotopes of the Tomsk region were examined for the presence of Borrelia DNA, depending on their genus (Ixodes and Dermacentor). DNA detection of Borrelia burgdorferi sensu lato complex (B. burgdorferi, B. garinii, B. afzelii) and B. miyamotoi was performed by real-time PCR. Results. The high number of ixodid ticks in local areas of natural biotopes (up to 200.0 specimens/km at the height of the epidemiological season), as well as the failure to comply with personal prevention measures, determines a consistently high rate of referral of the population of the Tomsk region to medical organizations due to tick bites. The number of requests annually averages 20.8 thousand. As a result of an annual study using PCR tests of ticks taken from people who applied to emergency prevention centers, Borrelia DNA was detected on average in 40% of samples; blood samples from individuals affected by tick bites were positive on average in 3.7% of cases. In the period 2015-2019 spirochetes B. garinii and B. afzelii were most often found in the tissues of ixodid ticks. Since 2020, the species Borrelia miyamotoi has been included in the list of pathogenic borrelia species to be monitored in the Tomsk region – spontaneous infection of ticks (Ixodes) was 3%. The maximum values both in the number of patients with ixodic tick-borne borreliosis and in the density of infections per 10,000 hectares (90-110 cases) are observed in the south of the Tomsk region (Asinovskyi, Kozhevnikovskyi, Krivosheinskyi, Tomskyi, Shegarskyi districts, the city of Tomsk). In the epidemic season of 2020, the number of laboratory-confirmed cases of non-erythema ixodic tick-borne borreliosis was more than 2.5 times higher than the number of diseases with skin manifestations. Conclusion. The large number of ixode mites in natural biotopes, the high degree of their infection with pathogenic spirochetes indicate the presence of active natural foci of ixodic tick-borne borreliosis in the Tomsk region. The study of the genotypic diversity of pathogenic borrelias in relation to the species diversity of vectors, the analysis of the clinical manifestations of different etiological variants of tick-borne borreliosis (mono- and mixed infections), as well as the development of an algorithm for differential diagnostic search and a model for predicting the outcomes of the infectious process in tick-borne borreliosis and mixed infections are priority directions of problem-oriented scientific research in Tomsk region.

Challenges to infection control in early communication intervention: A scoping review.

BackgroundPersonal protective equipment (PPE) and infection prevention and control (IPC) measures are crucial to preventing the spread of coronavirus disease 2019 (COVID-19). This study used a scoping review to investigate the challenges that exist when speech–language therapists (SLTs) use IPC measures for providing early communication intervention (ECI).ObjectivesTo describe existing, recent literature on PPE and IPC measures used in early intervention through a scoping review (steps 1–5) and to consult local clinicians to investigate how SLTs who provide ECI in South Africa relate to these findings (step 6 of the scoping review).MethodA scoping review was performed which followed the PRISMA-ScR framework. Because of limited literature on PPE and IPC measures used by SLTs in providing ECI, the inclusion criteria were adjusted to include PPE and IPC measures used by healthcare workers (HCWs) who provide early intervention to the population of infants and toddlers up to 3 years old. At the time of the review, articles were not older than 10 years and were published between 2011 and 2020. The scoping review included a consultation with South African SLTs who provide ECI, including during the COVID-19 pandemic. A pilot study was conducted prior to the consultations. Seventeen clinicians were included in total. Data from both the pilot study and main consultation were transcribed and analysed in the results using thematic analysis.ResultsFourteen articles were included in the study. The scoping review of existing literature identified challenges to implementing IPC measures, namely the care and behaviour of young children, infrastructure and system challenges, poor compliance and lack of training and a lack of standard IPC protocols. Clinicians in the consultation phase confirmed these challenges and reported that IPC measures did not consider ECI populations nor the settings in which services were provided. Suggestions from the literature for improved infection control included hand hygiene, improved supplies and infrastructure and education and training. Clinicians in the consultation added practical suggestions for implementing IPC measures within ECI, which included an increase in parent-led intervention as well as cleaning and disinfection strategies.ConclusionThis study identified challenges and recommendations of SLTs who use PPE and IPC measures whilst providing ECI. Understanding these challenges can benefit ECI services and future research efforts focused on improving ECI services whilst maintaining IPC standards.

Effect of the COVID-19 Pandemic on Compliance with Contact- and Droplet-precaution Measures in Siriraj Hospital’s Internal Medicine and Pediatrics Ward Nurses

Objective: To determine the effect of the COVID-19 pandemic on personal medical discipline toward infection preventive measures.Materials and Methods: An online questionnaire on personal preventive measure was developed. The content of the questionnaire was reviewed by content experts and tested for internal consistency reliability. Nurses in the Internal Medicine and Pediatrics wards were invited to answer the questionnaire.Results: In total, 188 individuals were included. Sixty-five percent of the protective measure statements showed a statistical improvement in compliance during the pandemic. Most of the protective measures, including hand washing, wearing a mask, and wearing glasses or a face shield, were statistically more complied with during the pandemic. However, some important protective measures, such as wearing a mask when performing aerosolgenerating procedures or when in close contact with droplet-precaution patients, did not show a statistically significant increase in compliance during the pandemic. There was no significant correlation between the demographic data and compliance level. The main reasons for non-compliance were time constraints, thought that the measures are not important, and equipment inadequacy.Conclusion: During the COVID-19 pandemic, there was some improvement in compliance with contact- and dropletprecaution measures in Siriraj Hospital’s Medicine and Pediatrics wards, but compliance with measures against some high-risk procedures that can spread the infection, such as aerosol generation or contacting with droplets, were not followed properly. The importance of precaution measures should be emphasized and the adequacy of protectiveequipment should be addressed to reduce the risk of spreading infection to healthcare workers and other patients.

Changes in Compliance With Personal Preventive Measures and Mental Health Status Among Chinese Factory Workers During the COVID-19 Pandemic: An Observational Prospective Cohort Study.

Coronavirus Disease 2019 (COVID-19) vaccination together with good compliance with personal preventive measures may help eradicate the ongoing pandemic. This observational prospective cohort study investigated the changes in compliance with personal preventive measures, depressive symptoms, and sleep quality among factory workers within a 3-month follow-up period. A total of 663 workers were recruited by a stratified multi-stage cluster sampling in March 2020, and all of them completed a follow-up survey three months later. Multilevel logistic and linear regression models (level 1: factories; level 2: individual participants) were fitted. A significant decline was observed in consistent facemask wearing in workplace (from 98.0 to 90.3%, P < 0.001) and in other public spaces (from 97.1 to 94.4%, P = 0.02), sanitizing hands (from 70.9 to 48.0%, P < 0.001), household disinfection (from 47.7 to 37.9%, P < 0.001) and probable depression (from 14.9 to 1.5%, P < 0.001) over the follow-up period. A significant improvement in avoiding crowded places (from 69.8 to 77.4%, P = 0.002) and sleep quality (proportion of participants reporting poor sleep quality dropped from 3.9 to 1.2%, P = 0.002) was also observed. Efforts are needed to maintain compliance with personal preventive measures during the pandemic. Mental health problems were uncommon and likely to be one-off among Chinese factory workers.

Development of an Easily Reproducible Cough Simulator With Droplets and Aerosols for Rapidly Testing Novel Personal Protective Equipment.

The current COVID-19 pandemic has produced numerous innovations in personal protective equipment, barrier devices, and infection mitigation strategies, which have not been validated. During high-risk procedures such as airway manipulation, coughs are common and discrete events that may expose healthcare workers to large amounts of viral particles. A simulated cough under controlled circumstances can rapidly test novel devices and protocols and thus aid in their evaluation and the development of implementation guidelines. Physiologic cough simulators exist but require significant expertise and specialized equipment not available to most clinicians. Using components commonly found in healthcare settings, a cough simulator was designed for clinicians to easily assemble and use. Both droplet and aerosol particle generators were incorporated into a bimodal experimental system. High-speed flash photography was used for data collection. Using a gas flow analyzer, video recordings, and high-speed digital photography, the cough and particle simulators were quantitatively and qualitatively compared with known physiologic cough parameters and in vivo Schlieren imaging of human coughs. Based on our validation studies, this cough and particle simulator model approximates a physiologic, human cough in the context of testing personal protective equipment, barrier devices, and infection prevention measures.

Skin injuries due to Personal Protective Equipment and preventive measures in the COVID-19 context: an integrative review.

to identify the diverse scientific evidence on the types of skin lesions caused due to the use of Personal Protective Equipment in health professionals during the COVID-19 pandemic and to verify the recommended prevention measures. this is an integrative review carried out in the MEDLINE, CINAHL, LILACS, SCOPUS, Science Direct, Web of Science and SciELO databases. The search was conducted in a paired manner, constituting a sample of 17 studies categorized according to the types of skin lesions and preventive measures. the main types of skin lesions related to mask use were stage 1 pressure ulcers, acne and cutaneous depression. Regarding the use of glasses and face shields, the most frequent were stage 1 and 2 pressure ulcers. Xerosis and irritant contact dermatitis occurred due to using gloves and protective clothing, respectively. The main preventive measures recommended were using hydrocolloid or foam dressing in the pressure regions, moisturizers and emollients. a considerable number of skin lesions associated with using the equipment were noticed, and the data obtained can guide the professionals in identifying risks and promoting preventive measures to avoid their occurrence.

Mechanisms and ways of transmission of SARS-CoV-2 coronavirus infection

The relevance of the problem. A new coronavirus infection caused by the SARS-CoV-2 virus has created an emergency situation of international importance. The incidence of it is characterized by a rapid spread across all countries, high morbidity rates, severe complications and mortality. Despite the fact that there are currently vaccines, it is not yet possible to stop the infection. Of particular importance as a preventive measure is the impact on the second link of the epidemic process. In this connection, obtaining objective data on the mechanisms and ways of spreading the SARS-CoV-2 virus will allow for more rational preventive measures and significantly reduce the risk of transmission of infection. The aim is to analyze current data on the mechanisms and ways of spreading the COVID-19 pathogen from available literature sources and to consider possible measures to influence the second link of the epidemiological chain in order to reduce the risks of infection. Materials and methods. The selection of peer-reviewed literature published from 2019 to 2021 was carried out. in the PubMed database and e-Library.ru, as well as links in articles. To obtain statistical data, the Internet resources of the World Health Organization (WHO), open data of Rospotrebnadzor, the Ministry of Health of the Russian Federation, Rosstat were used. Results. Analysis of scientific sources containing information on the mechanisms and ways of transmission of the new coronavirus infection COVID-19 indicates that the authors in their publications mention almost all the mechanisms and ways of transmission of this disease, but to varying degrees of their significance. The main mechanism of the spread of the SARS-CoV-2 virus is aspiration with airborne and airborne dust transmission routes. At the same time, the effect of contact, fecal-oral mechanisms is not excluded, the probability of the implementation of the vertical mechanism of transmission of the pathogen from the mother to the child, as well as the genital tract, is being studied. An important measure for the prevention of a new infection is the impact on the second link of the epidemic process, especially ensuring the highly efficient operation of ventilation and air conditioning systems in medical institutions and public places with a massive crowd of people, as well as compliance with personal preventive measures and disinfection measures.

Knowledge, Attitude and Practices of Antenatal Women Regarding Personal Preventive Measures for COVID-19 Infection

Objective: To identify level of knowledge about disease, attitude and behaviors in antenatal women contributing to ongoing COVID-19 pandemic that is still on the rise. Study Design: Cross-sectional descriptive study Place and Duration of Study: Department of Obstetrics &amp; Gynaecology, Avicenna Hospital Lahore from 5th November 2020 to 4th February 2021. Methodology: Two hundred pregnant women who visiting the OPD of the hospital were enrolled. A pre-validated questionnaire was used to assess KAP towards COVID-19. Results: More than 70% were familiar with COVID-19 infection; most common source of information was news channels (76.5%). Large proportion of patients showed poor knowledge of disease transmission and symptomatology. 50% believed that infection is very contagious but only 49% reported that route of spread is respiratory droplets and 21% believed it spreads via direct contact also. Very few women showed a positive perception of disease prevention and control (&lt;50%). Conclusion: Obstetric patients have sufficient knowledge regarding COVID-19 pandemic but their attitude and practices are not sufficient to stop the spread of disease in Pakistan. Key words: COVI-19, Pandemic, Awareness, Attitude, Practices

Adoption of Preventive Measures During the Very Early Phase of the COVID-19 Outbreak in China: National Cross-sectional Survey Study.

BackgroundThe outbreak of COVID-19 in China occurred around the Chinese New Year (January 25, 2020), and infections decreased continuously afterward. General adoption of preventive measures during the Chinese New Year period was crucial in driving the decline. It is imperative to investigate preventive behaviors among Chinese university students, who could have spread COVID-19 when travelling home during the Chinese New Year break.ObjectiveIn this study, we investigated levels of COVID-19–related personal measures undertaken during the 7-day Chinese New Year holidays by university students in China, and associated COVID-19–related cognitive factors.MethodsA cross-sectional anonymous web-based survey was conducted during the period from February 1 to 10, 2020. Data from 23,863 students (from 26 universities, 16 cities, 13 provincial-level regions) about personal measures (frequent face-mask wearing, frequent handwashing, frequent home staying, and an indicator that combined the 3 behaviors) were analyzed (overall response rate 70%). Multilevel multiple logistic regression analysis was performed.ResultsOnly 28.0% of respondents (6684/23,863) had left home for >4 hours, and 49.3% (11,757/23,863) had never left home during the 7-day Chinese New Year period; 79.7% (19,026/23,863) always used face-masks in public areas. The frequency of handwashing with soap was relatively low (6424/23,863, 26.9% for >5 times/day); 72.4% (17,282/23,863) had frequently undertaken ≥2 of these 3 measures. COVID-19–related cognitive factors (perceptions on modes of transmission, permanent bodily damage, efficacy of personal or governmental preventive measures, nonavailability of vaccines and treatments) were significantly associated with preventive measures. Associations with frequent face-mask wearing were stronger than those with frequent home staying.ConclusionsUniversity students had strong behavioral responses during the very early phase of the COVID-19 outbreak. Levels of personal prevention, especially frequent home staying and face-mask wearing, were high. Health promotion may modify cognitive factors. Some structural factors (eg, social distancing policy) might explain why the frequency of home staying was higher than that of handwashing. Other populations might have behaved similarly; however, such data were not available to us.

Self-Reported Compliance with Personal Preventive Measures among Office Workers After Work Resumption during the COVID-19 Outbreak in Pakistan.

ABSTRACT.As the lockdowns have been lifted to relieve pressure on the economy, strict adherence to personal preventive measures (PPMs) in offices is essential to control the COVID-19 pandemic. This study investigated self-reported compliance with three PPMs among a sample of office workers in Karachi, Pakistan. A cross-sectional survey with participants were adult office workers who had resumed work in Karachi, Pakistan. All full-time employees aged ≥ 18 years who had resumed work in the offices were invited to complete the survey. Of 487 workers who were invited, 411 (84.4%) completed the survey between March 1 and March 20, 2021. We examined the effects of sociodemographic factors, individual-level factors, interpersonal-level factors, and social-structural–level factors using logistic regression models. Of the total sample, 192 (46.7%) reported always wearing a face mask in the workplace. Self-reported sanitizing of hands (46.0%) was comparable to use of face masks, whereas avoiding crowded places (21.2%) was less common. Perceived effectiveness of individual preventive measures (adjusted odds ratios [AORs] from 1.19 to 1.42; confidence intervals (CIs) 1.04–1.37 to CI 1.18–1.71), perceived effectiveness of governmental preventive measures (AORs from 1.23 to 1.39 CI 1.02–1.47 to CI 1.12–1.72), and number of preventive measures implemented by the office (AORs from 1.20 to 1.26 CI 1.09–1.31 to CI 1.13–1.39) were associated with self-reported compliance with PPMs. Perceived preparedness of medical system in Karachi (AOR 1.44, CI 1.08–1.93) was only associated with self-reported sanitizing of hands. Reduced compliance to PPMs was observed; hence, efforts need to be made to ensure strict adherence to PPMs.

Impact of COVID-19 on TB epidemiology in South Korea.

SETTING: Five referral hospitals, South Korea.OBJECTIVE: To assess epidemiological changes in TB before and during the COVID-19 pandemic.DESIGN: This was a multicentre cohort study of 3,969 patients diagnosed with TB.RESULTS: We analysed 3,453 patients diagnosed with TB prior to the COVID-19 pandemic (January 2016-February 2020) and 516 during the pandemic (March-November 2020). During the pandemic, the number of patients visits declined by 15% from the previous 4-year average, and the number of patients diagnosed with TB decreased by 17%. Patients diagnosed during the pandemic were older than those diagnosed before the pandemic (mean age, 60.2 vs. 56.6 years, P < 0.001). The proportion of patients to have primary TB at a younger age (births after 1980) among those diagnosed with TB was significantly lower during the pandemic than before (17.8% in 2020 vs. 23.5% in 2016, 24.0% in 2017, 22.5% in 2018, 23.5% in 2019; P = 0.005).CONCLUSIONS: The COVID-19 pandemic resulted in a reduction in the number of visits to respiratory departments, leading to fewer patients being diagnosed with TB. However, our results suggest that universal personal preventive measures help to suppress TB transmission in regions with intermediate TB burden.

Changes in respiratory virus infection trends during the COVID-19 pandemic in South Korea: the effectiveness of public health measures.

Background/AimsStudies on the effectiveness of public health measures to prevent respiratory virus transmission in real-world settings are lacking. We investigated the effectiveness of universal mask use and adherence to other personal preventive measures on the changing viral respiratory infection patterns during the coronavirus disease 2019 (COVID-19) pandemic.MethodsData were extracted from the South Korean National Respiratory Virus Sentinel Surveillance System. During the COVID-19 pandemic, a cross-sectional survey on adherence to personal preventive measures was conducted. Additionally, the number of subway passengers was analyzed to estimate physical distancing compliance.ResultsDuring the pandemic, adherence to personal preventive measures significantly increased, particularly indoors and on public transportation. Respiratory virus trends were compared based on laboratory surveillance data of 47,675 patients with acute respiratory infections (2016 to 2020). The 2019 to 2020 influenza epidemic ended within 3 weeks, from the epidemic peak to the epidemic end, quickly ending the influenza season; with a 1.8- to 2.5-fold faster decline than in previous seasons. Previously, the overall respiratory virus positivity rate remained high after the influenza seasons had ended (47.7% to 69.9%). During the COVID-19 pandemic, this positive rate, 26.5%, was significantly lower than those in previous years. Hospital-based surveillance showed a decreased number of hospitalized patients with acute viral respiratory illnesses.ConclusionsThis study suggests that high compliance to the use of personal preventive measures in public might reduce the incidence of all respiratory virus infections and its hospitalization rates, with no additional quarantine, isolation, or contact screening.

Rapid COVID-19 Antigen Testing in Croatia: Risk Perception Plays an Important Role in the Epidemic Control.

Aim: To explore the clinical presentation and epidemiological history of the subjects who underwent SARS-CoV-2 antigen testing.Methods: We included 1,000 consecutive subjects who presented themselves at the diagnostic clinic in Croatia and analyzed their symptoms and epidemiological history. All subjects were classified into three groups, according to their reason of arrival; symptomatic, contacts of confirmed patients, and those who were tested due to administrative reasons.Results: On average, there were 24% of positive antigen results; the positivity rate was 51% among symptomatic, 16% in contacts, and 5% of administrative patients. The commonest symptoms of the disease included febrility and anosmia. We developed a clinical score to predict SARS-CoV-2 positivity, which had an area under the curve of 79.3 [95% confidence intervals (CI) 75.8–82.8]. Contact with the isolated person [odds ratio 0.54 (95% CI 0.31–0.94)] and international travel had a protective effect [0.20 (0.09–0.43)], suggesting that risk perception and mandatory pretravel measures had a key role in the determination of the infection risk.Conclusions: A combination of clinical symptoms can have reasonable predictive power for an antigen-positive test result. Risk perception seems to have a role in the epidemic spread, probably via stricter adherence to personal preventative measures.

Children’s Perception Scale of Head Lice Infestation (CPS-HLI): Design and Psychometrics

Background: Pediculosis is a common ectoparasitic infestation that involves especially the skin of children worldwide. Studying the children’s perception of the disease’s risk factors, the effectiveness of personal preventive measures, and its implications for their health could be a major leap forward in health promotion activities. Objectives: This study aimed to develop and evaluate the psychometric properties of the Children’s Perception Scale of Head Lice Infestation (CPS-HLI) and its initial feasibility assessment for use on Iranian and possibly other elementary school children. Methods: The scale’s items were retained based on an extensive literature search and classified into the underlying constructs of the extended health belief model (EHBM). An expert panel endorsed the qualitative content and face validity of the preliminary draft, and 47 items remained for quantitative validity testing on a sample of 362 elementary school students in the city of Paveh, West of Iran. Explanatory and confirmatory factor analyses (EFA and CFA) were employed to test the content and structural validity of the constructed instrument. Cronbach's alpha and intra-class correlation coefficients were calculated to assess the internal consistency and reliability of the scale. Results: The values of Lawshe's content validity index (0.90) and content validity ratio (0.77), the subscales’ Cronbach's alpha (0.59), and intra-class correlation (0.72) coefficients confirmed plausible internal consistency of the scale. The values of root mean square error of approximation (RMSEA) (&lt; 0.08 with χ2 &lt; 0.05), Tucker-Lewis index (TLI), and comparative fit index (CFI) &gt; 0.9 approved the applied statistical model’s goodness of fit. The ranges of Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy for the underlying subscales (0.49 - 0.74) and the statistically significant result of Bartlett’s test of sphericity (P &lt; 0.001) confirmed the patterned relationship among the constructed scale’s items. The principal component analysis that was performed using STATA favored the 11-factor solution. Conclusions: The study findings support the construct validity of CPS-HLI for use in studies on children’s perception of head lice infestation risk factors, the effectiveness of personal preventive measures, and the disease implications for their health and well-being. Further cross-cultural and cross-national validation studies are recommended for using the instrument in a wider range of populations and settings.

Design and Fabrication of an Automated Low-Cost Non-Contact Temperature Scanner and Sanitizer for Covid-19 Prevention

The rate at which the novel virus Covid-19 spread across the world in an alarming rate with high rate of death of the infected persons is quite disturbing, hence the need to checkmate its spread by quickly identifying persons with the symptoms of this viral infection. This paper discusses the development of an automated low-cost non-contact temperature scanner and sanitizer. The system automatically detects a human being, scans for temperature, and sanitizes the person with no interference required. The circuit for the system comprises an Arduino microcontroller, LCD display, relays, ultrasonic sensors, temperature sensor, 12v DC pump motion sensor and a high pressure 12v DC pump. The temperature sensor (MLX90614) senses the temperature, certifies that the value is within the specified range as controlled by its ultrasonic sensor and displays the temperature on the LCD. Thereafter, an ultrasonic sensor activates the 12V DC pump to dispense the sanitizer. At the disinfectant chamber, the motion sensor will trigger the high-pressured DC pump when it senses movement, it dispenses the body sanitizer through the nozzles. C++ was used to program the Arduino in Arduino user interface. The entire process takes 60seconds and it helps to maintain personal preventive measures as well as detecting a possible symptomatic person as fever with high temperature which is one of the major symptoms of Covid-19. The device has been tested and works effectively, and it will be very useful for any organization with one or more buildings. It can be positioned at the entrance of buildings to sanitize and scan all staff and visitors against Covid-19. Keywords: Arduino, Covid-19, Hand sanitizer, Ultrasonic sensor, Temperature Scanner

Cost of vaccine delivery strategies in low- and middle-income countries during the COVID-19 pandemic

BackgroundThe COVID-19 pandemic has disrupted immunization services critical to the prevention of vaccine-preventable diseases in many low- and middle- income countries around the world. These services will need to be modified in order to minimize COVID-19 transmission and ensure the safety of health workers and the community. Additional budget will be required to implement these modifications that ensure safe delivery. MethodsUsing a simple modeling analysis, we estimated the additional resource requirements associated with modifications to supplementary immunization activities (campaigns) and routine immunization services via fixed sites and outreach in 2020 US dollars. We considered the following four categories of costs: (1) personal protective equipment (PPE) & infection prevention and control (IPC) measures for immunization sessions; (2) physical distancing and screening during immunization sessions; (3) delivery strategy changes, such as changes in session sizes and frequency; and (4) other operational cost increases, including additional social mobilization, training, and hazard pay to compensate health workers. ResultsWe found that implementing a range of measures to protect health workers and communities from COVID-19 transmission could result in a per-facility start-up cost of $466–799 for routine fixed-site delivery and $12–220 for routine outreach delivery, and $12–108 per immunization campaign site. A recurrent monthly cost of $137–1,024 for fixed-site delivery and $152–848 for outreach delivery per facility could be incurred, and a $0.32–0.85 increase in the cost per dose during campaigns. ConclusionsBy illustrating potential cost implications of providing immunization services through a range of strategies in a safe manner, these estimates can provide a benchmark for program managers and policy makers on the additional budget required. These findings can help country practitioners and global development partners planning the continuation of immunization services in the context of COVID-19.

SARS-CoV-2 Infection Risk Factors among Maintenance Hemodialysis Patients and Health Care Personnel In Outpatient Hemodialysis Centers.

Public health agencies outreach through Instagram during the COVID-19 pandemic: Crisis and Emergency Risk Communication perspective

BackgroundGovernmental and non-governmental institutions increasingly use social media as a strategic tool for public outreach. Global spread, promptness, and dialogic potentials make these platforms ideal for public health monitoring and emergency communication in crises such as COVID-19. ObjectiveDrawing on the Crisis and Emergency Risk Communication framework, we sought to examine how leading health organizations use Instagram for communicating and engaging during the COVID-19 pandemic. MethodsWe manually retrieved Instagram posts together with relevant metadata of four health organizations (WHO, CDC, IFRC, and NHS) shared between January 1, 2020, and April 30, 2020. Two coders manually coded the analytical sample of 269 posts related to COVID-19 on dimensions including content theme, gender depiction, person portrayal, and image type. We further analyzed engagement indices associated with the coded dimensions. ResultsThe CDC and WHO were the most active of all the assessed organizations with respect to the number of posts, reach, and engagement indices. Most of the posts were about personal preventive measures and mitigation, general advisory and vigilance, and showing gratitude and resilience. An overwhelming level of engagement was observed for posts representing celebrity, clarification, and infographics. ConclusionsInstagram can be an effective tool for health organizations to convey their messages during crisis communication, notably through celebrity involvement, clarification posts, and the use of infographics. There is much opportunity to strengthen the role of health organizations in countering misinformation on social media by providing accurate information, directing users to credible sources, and serving as a fact-check for false information.
