Social Distance with Tourists in U.S. Counties with the Highest Historical Numbers of Reported COVID-19 Cases

With destinations steadily ‘opening back up for business' (while COVID-19 cases are still high in many areas), there is an increasing need to consider residents. Integrating the cognitive appraisal theory and the affect theory of exchange, this work tests a structural model examining the degree to which residents' perceptions of COVID-19 precautionary measures explain emotions directed toward visitors, and ultimately their willingness to engage in shared behaviors with tourists. Data were collected from 530 residents in 25 U.S. counties with the highest percentages of historical COVID-19 cases per population. A total of 10 of the 12 tested hypotheses were significant, contributing to 60% and 85% of the variance explained in contending and accommodating emotions, and 53% and 50% of the variance explained in engaging in less intimate–distal and more intimate–proximal behaviors with tourists. The implications highlight the complementary use of the two frameworks in explaining residents' preference for engagement in less intimate–distal interactions with tourists.

Factors associated with low knowledge of biosafety in medical interns at a university in Peru in the context of the COVID-19 pandemic

Introduction: The right to pre-professional practices protected under Peruvian Law allows the student in the last year of the human medicine career to begin to participate in health care procedures and interventions under the guidance of a tutor. Objective: to determine the factors associated with low knowledge of biosafety in medical interns at a university in Peru in the context of the covid-19 pandemic. Methods: an observational, prolective and cross-sectional design was carried out. The sample consisted of 336 human medicine interns, who were selected by simple random probabilistic sampling. A valid and reliable instrument was used to determine the level of knowledge in biosafety. A bivariate and multiple logarithmic binary regression model was used to calculate the crude and adjusted prevalence ratio with their respective 95% confidence intervals for the factors associated with the level of knowledge in biosafety. Results: high, medium and low levels of knowledge of 44.6%, 26.8% and 28.6% respectively were found. Married marital status (RPA 0.418, 95% CI 0.181 – 0.968), living with people at risk for severe symptoms from covid-19 (RPA 0.472, 95% CI 0.344–0.647), undergoing medical internship in a hospital, and having been diagnosed by covid-19 in the last 12 months (RPA 0.586, 95% CI 0.387–0.887) were associated with a level of knowledge under biosafety by multiple logarithmic binary regression model. Discussion: married marital status, living with people at risk for severe symptoms of covid-19, undergoing medical internship in a hospital center and having been diagnosed with covid-19 have an inversely proportional relationship with low knowledge in biosafety.

Dodržování hygieny rukou v nemocničním prostředí - dotazníkový průzkum zaměřený na zjištění compliance v používání rukavic

Úvod: Hygiena rukou je považována za jedno z nejdůležitějších a nejúčinnějších opatření v prevenci a kontrole šíření infekcí. Hraje také zásadní roli při snižování výskytu infekcí spojených se zdravotní péčí. Hlavním cílem je posoudit dodržování hygieny rukou - se zvláštním zaměřením v používání rukavic při poskytování péče v lůžkových zařízeních. Metody: Průřezový dotazníkový průzkum dodržování standardů bezpečné zdravotní péče v lůžkových zařízeních na území České republiky v roce 2018 před pandemií COVID-19. Osloveno bylo celkem 80 lůžkových poskytovatelů zdravotních služeb v České republice. Odpovědi byly hodnoceny na 6stupňové škále od "vždy" (100 bodů) do "nikdy" (0 bodů). Analýza dat byla provedena pomocí IBM SPSS Statistics verze 22. Výsledky: Dotazník vyplnilo 2 049 zdravotnických pracovníků z 80 oslovených lůžkových zdravotnických zařízení na území České republiky. Respondenti byli rozděleni dle medicínského oboru. Respondenti pracovali v interních oborech (43 %), chirurgických oborech (28 %), na psychiatrii (14 %), v zařízeních dlouhodobé lůžkové péče (9 %) a v ostatních nezařazených oborech (6 %). Závěr: Předkládaná studie ověřila dobrou úroveň v dodržování hygienických standardů u poskytovatelů lůžkové péče v České republice. Identifikovány byly rozdíly v metodickém opatření pro hygienu rukou v České republice a mezinárodních doporučených postupech, které jsou podloženy vysokou úrovní vědeckých důkazů. Vhodným opatřením by bylo zavést národně akceptované klinické doporučené postupy s přesně vymezenou úrovní důkazů.Alternate :Introduction: Hand hygiene is considered one of the most important and effective measures for infection prevention and control. It also plays a vital role in reducing healthcare-associated/acquired infections. The main goal is to assess hand hygiene compliance - with a special focus on using gloves when providing care in inpatient settings. Methods: A cross-sectional survey on compliance with hand hygiene was conducted in health care facilities in the Czech Republic in 2018 before the COVID-19 pandemic. The participants were from 80 inpatient health care providers in the Czech Republic. Responses were scored on a 6-level scale, from "always" (100 points) to "never" (0 points). Data analysis was performed using IBM SPSS Statistics version 22. Results: The questionnaire was filled in by 2,049 health care personnel from 80 inpatient health care facilities in the Czech Republic. Respondents were further divided according to the medical specialty. Respondents worked in the field of internal medicine (43%), surgical fields (28%), psychiatry (14%), long-term care facilities (9%), and other non-classified fields (6%). Conclusions: The presented study verified the good level of declared compliance with hygiene standards in inpatient healthcare providers in the Czech Republic. Significant differences were found between the observed hand hygiene measures established in the Czech Republic and international best practices based on a high scientific evidence level. An appropriate measure would be to establish national clinical best practices based on convincing scientific evidence at the national level.

Decreased community-acquired pneumonia coincided with rising awareness of precautions before governmental containment policy in Japan.

The effectiveness of population-wide compliance to personal precautions (mask-wearing and hand hygiene) in preventing community-acquired pneumonia has been unknown. In Japan, different types of nonpharmaceutical interventions from personal precautions to containment and closure policies (CACPs, e.g. stay-at-home requests) were sequentially introduced from late January to April 2020, allowing for separate analysis of the effects of personal precautions from other more stringent interventions. We quantified the reduction in community-acquired pneumonia hospitalizations and deaths and assessed if it coincided with the timing of increased public awareness of personal precautions before CACPs were implemented. A quasi-experimental interrupted time-series design was applied to non-COVID-19 pneumonia hospitalization and 30-day death data from April 2015 to August 2020 across Japan to identify any trend changes between February and April 2020. We also performed a comparative analysis of pyelonephritis and biliary tract infections to account for possible changes in the baseline medical attendance. These trend changes were then compared with multiple indicators of public awareness and behaviors related to personal precautions, including keyword usage in mass media coverage and sales of masks and hand hygiene products. Hospitalizations and 30-day deaths from non-COVID-19 pneumonia dropped by 24.3% (95% CI 14.8-32.8) and 16.1% (5.5-25.5), respectively, in February 2020, before the implementation of CACPs, whereas pyelonephritis and biliary tract infections did not suggest a detectable change. These changes coincided with increases in indicators related to personal precautions rather than those related to contact behavior changes. Community-acquired pneumonia could be reduced by population-wide compliance to moderate precautionary measures.

What did nursing home residents think about COVID-19 prevention practices in the era of vaccination and treatment?

We surveyed 57 nursing home residents to assess the subjective impact of COVID-19 prevention practices. Residents were mostly accepting of testing and symptom screening; however, many would like more choices. Sixty-nine percent want to have some say in when or where to mask. Most (87%) residents want to return to group activities. Residents on long-stay units (58%) are more likely than residents on short-stay units (27%) to accept additional risk of COVID-19 transmission to increase their quality of life.

Partisanship, Religion, and Social Class: Attitudes and Behaviors in the Early Stages of the Covid-19 Pandemic

This article investigates differences in health precautions taken during the pandemic and the degree to which individuals had faith in the governments' response to Covid-19 in the early stages of the pandemic. Using a sample designed to be nationally representative as well as representative of three lockdown zones, we Pnd that local social-distancing policies, social class, religion, and political partisanship all iniuenced how Indonesians experienced the pandemic and their perceptions of the governments' response. We found that fear levels and pandemic behavior are associated with religion as well as economic status. Fear levels are much higher among lowest-paid Indonesians and among Muslims outside of the capital city Jakarta, while non-Muslims reported greater levels of precaution-taking measures. Though among Islamic parties'voters, the difference is less pronounced, there are notable partisan differences as stronger predictors of attitude and behavior during the pandemic where there have been coniicts between local and national health authorities.

Compliance with Standard Precaution Practices During the Early Phase of the Covid-19 Pandemic among Nurses in Nigeria

Background: Nurses serve at the frontline during disease outbreaks. While measures have been adopted to control the rapid spread of the Covid-19 pandemic, little is known about the level of compliance of nurses to standard precaution practices during the early phase of the pandemic. Objective: This study aimed to assess compliance with standard precaution practices (SPPs) among 713 nurses in Nigerian hospitals during the early phase of the pandemic. Method: The study adopted a descriptive cross-sectional design using an anonymous online questionnaire to elicit data from respondents. Data were analysed with the Statistical Package for the Social Sciences, version 25. Chisquare test and multiple regression analyses were also conducted where appropriate. Results: Findings from this study indicated that 448 (62.8%) of the respondents had good knowledge of Covid-19 and 265 (37.2%) had poor knowledge. Also, 529 (74.2%) had good compliance with the practice of standard precautions, and 184 (25.8%) showed non-compliance. A significant association was found between the age of nurses (X-2=14.034 p=0.015), years of experience (X-2=8. 636 p =0.035) and their overall compliance with the practice of standard precautions. Conclusion: During the early phase of the Covid-19 pandemic in Nigeria, although over an average of the nurses had good knowledge of the disease, over one-third had poor knowledge, and one-quarter showed poor compliance with standard precautions. Interventions to improve the knowledge and compliance of health workers during the early phase of disease outbreaks are hereby advocated, as 21.3% had no previous training on Covid-19.

Knowledge of nosocomial infections, standard precautions, and source of information among physiotherapy undergraduates in Sri Lanka; an observational study.

BACKGROUND: Physiotherapists and physiotherapy undergraduates have direct contact with patients which make them transmitters of infections if they do not follow standard precautions. Hence, the purpose of this study was to assess the knowledge of nosocomial infections, standard precautions, and source of information among physiotherapy undergraduates in Sri Lanka. METHODS: An observational Google based survey study was conducted among 294 physiotherapy undergraduates, of which there were 103 in University of Peradeniya, 103 in University of Colombo, and 88 in General Sir John Kotelawala Defence University. The Infection Control Standardized Questionnaire comprising three domains: knowledge of nosocomial infections, standard precautions and hand hygiene was used for data collection along with a self-constructed data sheet for socio-demographic information and source of information. RESULTS: Participants achieved mean knowledge of 67.1 ± 16.8, 84.4 ± 14.7 and 66.4 ± 15.4 for nosocomial infections, standard precautions, and hand hygiene respectively. Of the total sample, 225 (76.5%) achieved adequate level of total knowledge. Eighty-three of them (28.3%) equally mentioned, formal teaching at faculty and informal sources as the most important source of knowledge. There was no significant impact of university and the duration of clinical exposure on knowledge of nosocomial infections, standard precautions, hand hygiene and total knowledge. The study year has a significant impact on standard precautions (P = 0.004) and total knowledge (P = 0.035) and final years had highest knowledge compared to the other study years. CONCLUSION: Knowledge of nosocomial infections and infection control measures were satisfactory among the physiotherapy undergraduates in Sri Lanka. Further developments of formal sources of information about nosocomial infections are recommended.

Knowledge, attitude and adherence to standard precautions among frontline clinical physiotherapists during the COVID-19 pandemic: a cross-sectional survey

Purpose: To investigate the knowledge of pathology and prevention of the novel coronavirus (COVID-19), attitude towards clinical practice, and adherence to standard precautions among clinical physiotherapists during the pandemic. Material(s) and Method(s): A snowballing method was used to recruit physiotherapists (across 53 countries) who responded to a newly designed and validated survey on the participants’demographics, knowledge of COVID-19, attitude, practices, and standard precaution adherence during the pandemic. Data were analysed using descriptive statistics, Cronbach’s Alpha, Pearson’s correlation, and ANOVA. Result(s): All participants (n = 2550, 100%) were knowledgeable on COVID-19 symptomatology. However, only (n = 312, 12.2%) were actively involved in the management of confirmed cases. The percentage score of participants’knowledge regarding COVID-19 pathology, and prevention, their attitude, and adherence to standard precautions averaged 77.73 ±10.11, 89.70 ±9.26, 77.44 ±7.04, and 61.59 ±16.63, respectively. Knowledge about COVID-19 pathology differed significantly across demographic variables (p <0.001, Ƞ2 ≤0.07). Most participants (n = 1936, 75.9%) reported an inadequate supply of personal protective equipment (PPE). Conclusion(s): Participants had good knowledge of COVID-19 pathology and a positive attitude towards safe clinical practice. However, adherence to standard precautions was suboptimal due to inadequate infectious disease training and PPE supply.Copyright © 2021 Informa UK Limited, trading as Taylor &Francis Group.

Radiographers' knowledge, attitude and adherence to standard COVID-19 precautions and the policy implications: a national cross-sectional study in Nigeria.

BACKGROUND: We investigated the knowledge of COVID-19 pathogenesis and prevention, attitude, and adherence to safe clinical practices among radiographers during the pandemic and made some informed policy recommendations. MATERIALS AND METHODS: The study was an online cross-sectional survey. The questionnaire captured data on respondents' demographics, knowledge of COVID-19, attitudes, practices, and standard precaution adherence during the pandemic. Data were analysed using descriptive statistics, Pearson's correlation and one-way ANOVA tests. RESULTS: Of the 255 respondents, 17.3% were actively involved in the management of COVID-19 cases. Participants had high scores regarding their knowledge of COVID-19 pathology (82.46 ± 8.67%), prevention (93.43 ± 7.11%) and attitude (74.11 ± 11.61%), but low compliance to safety precautions (56.08 ± 18.56%). Knowledge about COVID-19 prevention strategies differed significantly across educational qualifications, F(3, 251) = 4.62, p = .004. Similarly, levels of compliance with safety precautions differed across educational qualification (F[3, 251] = 4.53, p = .004) and years-in-practice (F[4, 250] = 4.17, p = .003). CONCLUSION: Participants' adherence to standard COVID-19 precautions was low. The level of professional qualification influenced participants' knowledge and safe practices during the pandemic. Upgrading the aseptic techniques and amenities in practice settings and broadening the infectious diseases modules in the entry-level and continuous professional education may improve radiographers' response to COVID-19 and future pandemics.Key messagesRadiographers whose qualifications were lower than a bachelor's degree had significantly less knowledge of COVID-19 prevention.Generally, radiographers had a positive attitude towards safe practices during the pandemic, but inadequate education, standard operational guidelines and resources affected their level of adherence.Apart from the shortage of personal protective equipment, poor infrastructural design and inadequate hygienic facilities such as handwashing stations, running water and non-contact hand sanitizer dispensers hampered adherence to COVID-19 precautions in low-resource settings.

Preisolation measures and clinical features for pediatric patients with suspicious COVID-19.

Background: In December 2019, many cases of COVID-19 were reported in Wuhan City, Hubei Province, China. In the following 3 months, the disease out broke in China. Preisolation measures was used to screen out COVID-19 patients in the pediatric respiratory ward of our hospital. Aims: To investigate the new measures for screening COVID-19 patients and to analyze the clinical features of children with suspicious COVID-19. Methods: A total of 50 preisolated children with suspicious COVID-19 who were admitted to our hospital in Mianyang, China, between January 28 and March 5, 2020, were included. Patients presented with fever and cough or fever accompanied by vomiting and diarrhea. A detailed epidemiological history screening was performed. A real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) was used to detect SARS-COV-2 nucleic acid. Low-dose chest computed tomography (CT) was applied when pneumonia was suspicious. Routine blood tests were performed to rule out COVID-19. Patients' data were collected, and the basic clinical features, epidemiological history, clinical manifestations, auxiliary examination results, and outcomes were analyzed and summarized. Results: No definite cases were detected, while two patients were suspected of having COVID-19. The pathogenic results of the 50 patients mainly included Mycoplasma pneumoniae, followed by Epstein-Barr virus, and rotavirus. Thirty-five patients suffered from bronchopneumonia. The preisolated patients had similar clinical and epidemiological characteristics as patients with fever, cough, vomiting, and diarrhea. Conclusions: Preisolation measures combined with pathogen screening can minimize the risk of hospital-acquired infections by preventing patients with suspicious COVID-19 from contacting other patients before they are explicitly excluded. Clinical analysis of the patients was helpful for clinical nursing management.

Living with HIV during COVID-19: knowledge and worry about COVID-19, adherence to COVID-19-related precautions, and HIV health outcomes.

The COVID-19 pandemic has been profound impacts on mental and physical health of individuals with chronic diseases. Thus, it is important to understand the effects of the COVID-19 pandemic on people living with HIV. We aimed to assess the association between COVID-19-related knowledge and worry, HIV-related health practices and outcomes, and adherence to precautions related to COVID-19, and possible associations of these factors with HIV treatment outcomes (ART adherence and viral load). A cross-sectional survey was conducted between October 2020 and February 2021 among 291 PLWH at two large university hospital HIV clinics in Izmir, Turkey. Additionally, the most recent HIV-RNA load, CD4 count was recorded using medical records. Logistic regression analyses were performed to determine predictors of self-reported adherence to COVID-19-related precautions, ART adherence and undetectable viral load. COVID-19-related worry, COVID-19-related knowledge, and ART adherence were significant predictors of adherence to COVID-19-related precautions. Furthermore, adherence to COVID-19-related precautions was a significant predictor of both ART adherence and undetectable viral load. Findings provide a unique aspect of the interrelations of COVID and living with HIV. Since health behaviors and outcomes for COVID-19 and HIV seem to be interrelated, treatment practices and interventions that address these simultaneously may enhance their efficacy.

How Have the COVID-19 Pandemic Precautions Affected the Frequency of Rotavirus and Enteric Adenovirus in Pediatric Patients?

Introduction: Approximately 70-80% of diarrheal cases in children are caused by viral pathogens. Viral gastroenteritis agents include rotavirus and adenovirus 40 and 41, particularly in those under two years of age, while norovirus and sapovirus can cause epidemics in individuals of all ages. In this study, we investigated the effect of Coronavirus disease-2019 (COVID-19) pandemic measures on the incidences of rotavirus and enteric adenovirus, which are the main viral agents of acute gastroenteritis in the pediatric age group. Materials and Methods: Patients <18 years of age, who were admitted to Tatvan State Hospital with the suspicion of acute gastroenteritis and whose rotavirus and enteric adenovirus antigen stool tests were analyzed, were scanned retrospectively. One year of the pre-pandemic period (01.03.2019-29.02.2020) and 1 year of the pandemic period (01.03.2020-28.02.2021) were included in the study. The rotavirus and adenovirus monthly test numbers, positivity rates, age, and gender of the patients were evaluated. Results: A total of 1,438 pediatric patient samples were analyzed during the pre-pandemic period and 345 pediatric patient samples had a preliminary diagnosis of acute gastroenteritis during the pandemic period. The adenovirus positivity rate was 1.8% (n=26) and the rotavirus positivity rate was 12% (n=173) during pre-pandemic period. These rates were 0.8% (n=3) for adenovirus and 8.6% (n=30) for rotavirus during the pandemic period, (respectively p=0.215;p=0.080). A significant decrease in stool sample analyses was observed during the pandemic (p<0.001). Rotavirus positivity rates were significantly lower in October (p=0.001), November (p=0.04), and December (p=0.04) during the pandemic period compared to the same months during the pre-pandemic period. Conclusion: As a result, COVID-19 pandemic precautions, such as maintaining social distance, wearing a mask, and complying with hygiene rules may have decreased the incidence of acute gastroenteritis and consequently reduced the number of stool samples analyzed during the pandemic period. Precautions taken during the pandemic period helped to prevent intestinal viral infections in children.

Awareness among Covid-19 precautions among patients visiting dental hospital

Background: The Coronavirus 2 syndrome (SARS CoV 2) or COVID-19 pandemic's rapid and widespread reach has become a major cause of concern to the dental health-care profession. The aim of this study is to assess the level of public knowledge, attitude and practice regarding COVID19 and infection control when visiting a dental hospital. Materials and Methods: An online questionnaire was created. Convenient sampling method was used for data collection. The sample population was 104 patients aged between 10-80 years. The data was entered, and analyzed using SPSS 20.0 version. Descriptive statistics, frequencies, and percentages were used to summarize the data. Chi square test was used to determine the association of study disciplines among the patients. P >0.10 was considered statistically not significant. Results: A total of 104 responses were obtained. All respondents had heard about coronavirus. Over 90% were aware of the severeness of the pandemic. 90% of the patients wear masks every time they visit a dental hospital. Over 80% disposed their masks after their visit to the dental hospital.About 88% were taking precautions. Over 90% were interested in knowing more about the disease and the necessary precautions to be taken while visiting a dental hospital. Comparison of the overall sections among various groups showed a nonsignificant result although some individual questions showed a statistically significant result. Conclusion: Dental health professionals need to conduct regular educational activities and training programs on infection prevention practices with respect to COVID-19 infection to serve their patients, not just their own practice but also to help the patients know about the severity of not taking precautions while visiting a dental clinic.

Isolation of Methicillin-Resistant Staphylococcus aureus from Wound Samples during the COVID-19 Pandemic: A Retrospective Study

Introduction: On March 11th, 2020, the World Health Organisation (WHO) declared the outbreak of the novel coronavirus disease caused by the Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) virus as a pandemic. This recently discovered b-coronavirus spread instantaneously across mainland China due to human-to -human transmission and crossed international borders aided by intercontinental travel. In most nations, the logarithmic growth of the cases very quickly overwhelmed the healthcare system which led to the overcrowding of the hospitals and led to a sudden surge in Hospital-Acquired Infections (HAIs). Implementation of contact precautions was implemented to control cross-infection. Aim: To determine the effect of Coronavirus Disease-2019 (COVID-19) on the prevalence of HAIs with special emphasis on Staphylococcus aureus (S. aureus). Materials and Methods: This three-year retrospective study (September 2018-August 2021) was undertaken at an apex tertiary care institute in Northern India. Wound swabs were collected and processed in the laboratory for the presence of aerobic bacterial isolates. S. aureus was identified using conventional methods and antimicrobial sensitivity was performed by the Kirby-Bauer disc diffusion method. Data was entered in Microsoft Excel and later analysed in International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) version 22.0. Results: A steady increase in the isolation of Methicillin-Resistant Staphylococcus aureus (MRSA) was noted during the study period (60.5% in 2018 to 78.1% in 2021). A statistically significant increase was noted in the detection of MRSA after the onset of the COVID-19 pandemic (p=0.018) despite the reduced number of surgeries conducted in the institution and rigorous execution of contact precautions. Conclusion: There was an increase in the rate of MRSA isolation during the study period. The increase was significantly affected by the onset of COVID-19. To contain the spread of MRSA, novel methods including preoperative screening of patients undergoing elective surgeries and periodic screening of hospital staff need to be implemented along with standard infection control precautions at all times.

Introduction: Narratives of Belonging-The Interrelation between Ontological-Epistemological Observations and Narrative Methodology

In a recent editorial, the Lancet reported that one of the consequences of pandemics is the detrimental impact "on the mental health of affected populations," and the current COVID-19 one is no different. Since its out-break at the end of 2019, "depressed mood, anxiety, impaired memory, and insomnia" are constant companions of people around the world. Many even experience "stress, burnout, depression, and post-traumatic stress disorder." Amongst its concerns, the Lancet notes the rising "misuse of substances" as a consequence of these mental health problems.1 One of the reasons for this global mental health crisis is the way the pandemic affects peoples' practices of community building and rituals of belonging. Having to wear masks, being required to keep at least 1.5 meters apart, not being able to meet (vulnerable) friends and family members, and even more drastic measures like weeklong lockdowns fundamentally disrupted everyday lives and reduced opportunities to socialize. What is normally taken for granted is being challenged. Around the world, these measures have been met by increasing demonstrations, often based on conspiracy theories and against commonsense precautions for preventing a potentially lethal disease. This conflict between reasonable precaution and emotional stress and pressure suggests disruptions of common narratives of belonging.

IoT-enabled Contactless Doorbell with Facial Recognition

The COVID-19 epidemic has altered lifestyles all across the globe, causing people to take additional safety precautions and make using a face mask a requirement. Face masks are becoming more popular, making it occasionally challenging for people to recognize other people. Children and the elderly in particular would have trouble identifying their masked guests, which poses a serious hazard because thieves or burglars would take advantage of the situation. In this study, a system was created using IoT and deep learning technologies that works as a unit to offer a contactless solution to the ongoing COVID-19 pandemic while also enabling home owners to keep track of their visitors and receive notifications when someone comes over. The contactless doorbell was created with the help of a Raspberry Pi and a modified ResNet-50 model using ArcFace loss as the feature extractor to efficiently extract visible features from a masked face and support very accurate recognition. Due to the lack of a real masked face dataset with sufficient data, this study used a data augmentation method to add masks to face images from a dataset. The model was able to achieve a recognition accuracy of 98.27% when evaluated using a masked LFW dataset. Furthermore, testing the face recognition model in real-Time with limited users, each with and without a mask yielded an accuracy of 100% in unmasked facial recognition and 90% on masked facial recognition. © 2023 IEEE.

Multi-subject collaborative prevention and control of adolescent myopia in China

Improving the system of adolescent myopia prevention and control and promoting adolescent healthy development is one of the main directions of healthy China construction in the new era. The paper reviewed national myopia policies and local practices and proposed reflections on the high burden and complex etiology of myopia among adolescents as well as unclear role and lack of coordination mandate during the COVID-19 epidemic. Based on the synergy theory through the analysis of the functional positioning of multiple subjects in the prevention and control of myopia the paper highlighted the multi-party linkage of government schools medical institutions communities families and markets profiling the resources and advantages of each subject as well as dynamic management of adolescent myopia as well as a multi-subject collaborative prevention and control system with national unity clear rights and responsibilities and long-term cooperation. © 2023 Journal of Chinese Agricultural Mechanization.

Considering the precautionary principle and its application to MRSA and SARS-CoV-2 as emerging novel pathogens of their time.

In the 1980s Contact Precautions were introduced as a precautionary measure to control the emerging threat of antimicrobial resistance in hospitals, particularly methicillin resistant Staphylococcus aureus (MRSA). Today, antimicrobial resistance remains a concerning global public health threat, and a focus for hospital patient safety priorities. In late 2019 a novel respiratory virus described as SARS-CoV-2, was reported. Just as MRSA had prompted control measures developed in the context of limited information and understanding of the pathogen, public health control measures against SARS-CoV-2 were promptly and strictly implemented. Whilst SARS-CoV-2 control measures were successful at containing the virus, numerous detrimental socio-economic and health impacts have led to a rebalancing of harms versus benefits and loosening of restrictions. Conversely, evidence collated over the past 50 years, suggests that Contact Precautions are not superior to well-applied standard infection prevention and control precautions in controlling MRSA acquisition in hospitals. Several harms associated with Contact Precautions, affecting patient safety, financial costs, and organisational culture, are described. However, rebalancing of hospital MRSA control policies has been slow to materialise. This commentary invites infection prevention and control policy makers to reflect and revise policies for the control of MRSA in hospitals so that harms do not outweigh benefits.

Evaluation of nurses' knowledge about protective precautions and experiences in terms of various factors during Covid-19 pandemic

Aim: The aim of the study was to evaluate nurses' knowledge of protective precautions and their experiences of various factors during the Covid-19 pandemic. Design: A descriptive cross-sectional study. Methods: In this descriptive cross-sectional study, the snowball method was selected for sampling to access nurses (n = 392) serving in the fight against the Covid-19 infection nationwide. The online data collection form had two parts: a sociodemographic form and a second part including 25 items on institutional protective measures, personal protective measures, and nursing care. Results: Most of the nurses caring for patients with Covid-19 were well-informed about institutional, personal, and patient protective precautions. The scores of female nurses, married nurses and those with children were higher. Multiple regression analysis revealed that in-service training, working in a clinic, and having colleagues diagnosed with Covid-19 positively affected knowledge, while having 0–5 years of professional experience negatively affected knowledge. Conclusion: This study may enlighten medical authorities and policymakers in their efforts to promote the quality of care delivered to patients with Covid-19 and the quality of working conditions of healthcare providers. © 2022 Central European Journal of Nursing and Midwifery.
