"To honour cleanness and shame filth”: medical facemasks as the narrative of nationalism and modernity in China

As the Covid-19 pandemic has swept across the world, the wearing of medical facemasks has become a hot topic on social media. In China, the relevant discourses are entangled with codes of medical science, national self-esteem and appropriated modernity. These discourses can be dated back to the narrative established by Dr Wu Lien-teh, the great fighter in the Manchurian plagues of 1910–1911 and 1920–1921. This paper reveals that Wu and his colleagues used different strategies when displaying to the Western world their achievements in the anti-plague battle and when proving the effectiveness of the Western medical and hygienic system to Chinese people. Wu and his colleagues used metonymies, analogues and metaphors on or related to medical facemasks to illustrate the possibility of building a modernised nation with sovereignty. Because the construction of a sanitary system in China has always been labelled as a patriotic movement (Rogaski, Ruth. 2004. Hygienic Modernity: Meanings of Health and Disease in Treaty-Port China. Berkeley: University of California Press, 285–298), the wearing of medical facemasks has constituted an important part of the narrative of nationalism and hygienic modernity. This discourse continues to play a significant role in today's campaign against the coronavirus.

Assessment of positive airway pressure treatment adherence and sleep quality in sleep apnea patients during COVID-19 pandemic: multi-center cross-sectional study results

Background: Patients with obstructive sleep apnea (OSA), related to their disease consequences and treatment modalities, are physically and mentally vulnerable during the outbreak. Objectives: To investigate the association between pandemic-related changes and positive airway pressure (PAP) adherence and sleep quality in OSA patients. Methods: This was a multi-center cross-sectional study, and the necessary data were collected prospectively. A total of 221 patients were included in the study, who were invited from four different centers from June 1 - December 1, 2020. Pittsburgh Sleep Quality Index (PSQI) was administered to evaluate sleep quality. Information on demographics positive airway pressure (PAP) device use, Coronavirus disease (COVID-19) a questionnaire collected related changes. Patients >18 years with a diagnosis of OSA and prescribed PAP treatment before the pandemic period were included in the study. Lack of cooperation with the questionnaires and incompliant with PAP treatment for longer than one year were the exclusion criteria. Results: Of the 221 participants, 79.2% were men. The mean apnea-hypopnea index was obtained at 40.8+or-24.3. A positive COVID-19 test was reported in nine cases, and three patients had hospitalization. During the pandemic, 102 (46.2%) subjects were retired, 26 (11.8%) lost their jobs, and 34 (15.3%) reported home office work or on-call or on leave. Poor sleep quality was found in 54 (24.4%) individuals. It was also reported that poor sleep quality was more common in those who reported mask use difficulty (38.7% vs. 18.9%;P=0.004) and increased or decreased PAP use (increased, decreased, no change in PAP use: 45.5%, 36.0%, 19.4%, respectively;P=0.01). The good sleep quality group had higher PAP use than the poor sleep quality group (6.2+or-1.5 vs. 5.3+or-2.4 night/week;P=0.002;6.2+or-1.5 vs. 5.5+or-2.2 hour/night;P=0.01). Conclusions: Pandemic period had several negative effects on sleep apnea patients regarding sleep quality and social lives which also influenced PAP adherence in OSA patients. Most patients did not change their regular PAP use attitudes during this period. Similar to the pre-COVID-19 disease period, PAP adherence and compliance positively influenced sleep quality;people who were "good sleepers" were the ones who were the "good PAP device users".

The danger of inappropriate use of personal protective equipment

The coronavirus pandemic is a global health emergency which has had widespread unforeseen mental health consequences. Those with borderline personality disorder are predisposed to poor coping strategies to manage such stress and require intense psychological input which was not widely available during the peak of the pandemic. It is likely that the coronavirus outbreak has had a significant impact on the mental stability of such patients aggravating deliberate self-harm behaviours. A 20-year old psychiatric in-patient with borderline personality disorder, held under Section III of the mental health act, presented to the adult plastic surgery team in Bristol with localised infection of her right forearm. Foreign bodies were easily palpable and imaging revealed linear metal objects. The patient reported that she had removed metal strips from her collection of face masks and inserted them into her forearm as an act of deliberate self-harm. The patient was taken to operating theatre for removal of these foreign bodies under general anaesthetic. After twenty-four hours of antibiotics she was discharged safely back to the psychiatric ward. Despite the epilogue of the COVID-19 pandemic facemasks are still mandatory within the hospital setting. Clinicians need to be aware of these unusual circumstances where a form of protective equipment was deconstructed to cause actual bodily harm. The purpose of this report is to promote awareness of this type of injury especially in those suffering from mental illness. The authors would suggest an alternative mask without any form of metal.

Performance Evaluation of State-of-The-Art 2D Face Recognition Algorithms on Real and Synthetic Masked Face Datasets

Face recognition systems based on Convolutional neural networks have recorded unprecedented performance for multiple benchmark face datasets. Due to the Covid-19 outbreak, people are now compelled to wear face masks to reduce the virus's transmissibility. Recent research shows that when given the masked face recognition scenario, which imposes up to 70% occlusion of the face area, the performance of the FR algorithms degrades by a significant margin. This paper presents an experimental evaluation of a subset of the MFD-Kaggle and Masked-LFW (MLFW) datasets to explore the effects of face mask occlusion against implementing seven state-of-the-art FR models. Experiments on MFD-Kaggle show that the accuracy of the best-performing model, VGGFace degraded by almost 40%, from 82.1% (unmasked) to 40.4% (masked). On a larger-scale dataset MLFW, the impact of mask-wearing on FR models was also up to 50%. We trained and evaluated a proposed Mask Face Recognition (MFR) model whose performance is much better than the SOTA algorithms. The SOTA algorithms studied are unusable in the presence of face masks, and MFR performance is slightly degraded without face masks. This show that more robust FR models are required for real masked face applications while having a large-scale masked face dataset. © 2023, Penerbit Akademia Baru. All rights reserved.

Face Mask Compliance and Complacency amongst Pakistan's Youth During the Third Wave of COVID-19

Objective: To assess the reasons for compliance with face mask usage amongst Pakistani youth. Study Design: Internet-based cross-sectional survey. Place and Duration of Study: Different cities of Pakistan, in April 2021. Methodology: Persons currently residing in Pakistan aged 18-29 were included in the study. The questionnaire included questions to identify self-perceptions of vulnerability to COVID-19, followed by questions about social situations where respondents wore facemasks. Results: A large number of (1,034,90%) respondents reported compliance with facemasks. Specifically, 1048(92%), 962(85%), and 850(75%) of respondents wore facemasks in healthcare facilities, marketplaces, or at work or school respectively. Nevertheless, when self-regulating, such as with family or around friends, compliance fell to 200(18%). Compliance turns to complacency when people are expected to self-regulate face mask usage. Females were more compliant than males (p<0.001). A large 779(68%) of compliant youth relied on information from Internet-based resources. Conclusion: The study correlates the reasons for compliance and complacency. In Pakistan, the most compliant youth get information from the Internet, particularly official websites and social media. © 2023, Army Medical College. All rights reserved.

Face masks as sources of cross-contamination during food preparation

Amid the COVID-19 pandemic, mask-wearing has become a common practice in the foodservice industry to prevent the spread of respiratory diseases. Like kitchen utensils, a mask may serve as a vehicle for cross-contamination of pathogens during food handling. The objective of this study was to quantify cross-contamination between tasks of handling contaminated chicken and chopping lettuce. Chicken breasts were inoculated with a high or a low level of nonpathogenic Escherichia coli surrogates (ca. 6 or 4 log CFU/ml) and sliced for 1, 5, or 10 min. During slicing, duplicate, single-use medical masks were touched each minute. One mask was immediately sampled, but the second mask was used to contaminate lettuce by touching the mask each minute while chopping the lettuce for 5 min. E. coli were enumerated from the second mask and lettuce. Masks touched while slicing both high- and low-inoculated chicken showed significant contamination (0.8-4.9 log CFU/cm2) after each slicing scenario of 1, 5, or 10 min (P > 0.05). Lettuce was significantly contaminated regardless of inoculation level (1.0-3.2 log CFU/g). Slicing time was a significant factor in some cases (P < 0.05), whereas inoculation level was not (P > 0.05). Data indicate masks can be a source of cross-contamination if not replaced appropriately.

The Sociability Argument for the Burqa Ban: A Qualified Defence.

Over the past decade, countries such as France, Belgium, Denmark, Austria, Latvia, and Bulgaria have banned face-coverings from public spaces. These bans are popularly known as 'burqa bans' as they seem to have been drafted with the aim of preventing people from wearing burqas and niqabs specifically. The scholarly response to these bans has been overwhelmingly negative, with several lawyers and philosophers arguing that they violate the human right to freedom of religion. While this article shares some of the concerns that have been raised, it argues that banning face-coverings in public is morally justified under certain conditions with the exception of facemasks that are necessary for the containment of infectious diseases, such as COVID-19. The reason for this is that those who publicly cover their face make it very difficult for other members of society to socially interact with them, especially for those who are deaf or hard-of-hearing, which is problematic in an age where many people are chronically lonely or at risk of becoming chronically lonely. As such, this article can be understood as a more elaborate, and arguably more sophisticated, defence of the justification that France offered for its face-covering ban before the European Court of Human Rights, namely that covering one's face undermines the conditions for 'living together'.

Microplastics/nanoplastics released from facemasks as contaminants of emerging concern.

Facemasks have become a global medical necessity and are a key preventive measure against COVID-19. Typically, facemasks (FMs) are fabricated from non-renewable polymers, particularly polypropylene (PP) and polyethylene (PE), which release secondary microplastic (MPs) due to the chemical, physical, and biological processes. In light of the widespread usage and improper disposal of single-use facemasks, there is concern about their environmental impact since they contribute to plastic pollution during and after pandemics. The repercussions of this have led to millions of tons of plastic waste being dumped into the environment. Due to lack of awareness and improper disposal, the occurrence of micro/nanoplastics released from facemasks in wastewater treatment plants and landfills poses a concern. Infiltration of wastewater treatment processes by micro/nanoplastics at various levels can be problematic because of their chemical nature and broad but small size. Thus, operational and process stability issues can arise during wastewater treatment processes. In addition, landfilling and illegal waste disposal are being used to dispose of potentially infectious COVID-19 waste, leading to an environmental threat to animal and human health and exacerbating plastic pollution. This paper reviews the fate of facemasks in the environment and the repercussions of improper waste management of facemasks in wastewater treatment plants, landfills, and ultimately the environment.

Meta analysis: the effect of age and gender on face mask use during COVID-19 pandemic

Background: Coronavirus disease 2019 (COVID-19) is a world health problem in early 2020. The first case of COVID-19 was found in Wuhan China, the use of masks is intended to control the transmission of the virus to others and as a preventive measure, namely by providing protection to users who do not infected with viral exposure. The purpose of this study was to estimate the extent of adherence to wearing masks in the elderly and women through a meta-analysis of the primary study which was carried out by the previous authors. Subjects and Method: This study was a meta-analysis with the following PICO, PICO. Population: general population, intervention: age (older > 46) and gender (female), comparison: age (young 12 - 45 years) and gender (male), outcome: use of masks. The articles used in this study were obtained from three databases, namely Google Scholar, Pubmed, and Science Direct. With keywords such as: "mask and COVID-19 transmission", "mask or COVID-19 transmission". The articles included are full-text English with an observational study design from 2020 to 2022. Article selection was carried out using PRISMA flow diagram. Articles were analyzed using the Review Manager 5.3 application. Results: A total of 9 case studies from Europe, America and Asia were selected for systematic review and meta-analysis. The results showed that people over 46 years of age were 1.54 times more likely to use a mask than those under 45 years old (aOR= 1.54;95% CI= 0.83 to 2.85;p= 0.170) and women were 1.12 times more likely to use a mask than men. -male (aOR= 1.12;95% CI= 0.78 to 1.61;p= 0.550). Conclusion: Older age and women are more likely to wear masks.

Effects of COVID-19 on customer service experience: Can employees wearing face masks enhance customer-perceived service quality?

Wearing a facemask is an effective part of personal hygiene management (WHO, 2020). Not only can it offer healthy people some protection against coronavirus disease 2019 (COVID-19) infection, but it can also reduce the spread of the virus. Wearing facemasks, as a part of the various regulations and guidelines encouraged by the Chinese government and hospitality firms, has been widely accepted by the public in the post-COVID-19 era in China. But few studies have considered the effects of employees wearing facemasks on the customer service experience. Based on signaling theory, this experimental study explores the effects of hotel employees wearing facemasks on customer perceptions of service quality. The results indicate three main effects. (a) Having employees wear facemasks can improve perceptions of customer service quality. (b) Customers commonly feel that female employees wearing facemasks could provide higher service quality than male mask-wearing employees, but the improvement in customer perception with male employees wearing facemasks is greater than the situation between facemask-less and facemask-wearing females. (c) Customer perceptions of employee expertise, employee trustworthiness, and hotel trustworthiness play serial mediating roles. Recommendations to help hotel managers improve customers' service evaluations during the COVID-19 pandemic are provided. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Determinants of COVID-19 vaccine uptake among undergraduate students in Kenya: a case study of the University of Nairobi

Objective: To evaluate the determinants of COVID-19 vaccine uptake among undergraduates in Kenyan universities. Design: Evaluation design. Setting: University of Nairobi's Main Campus, Nairobi, Kenya. Subjects: Undergraduate students at the University of Nairobi. Background: The fight against COVID-19 pandemic has utilized the information model for behavior change. The prevention behavior to adopt included wearing masks, keeping social distance and the COVID-19 vaccine uptake. However, there is still a knowledge-behavior among high-risk groups like the youth. Based on the Integrated Model of Behavior Prediction, the study sought to evaluate the determinants for the COVID vaccine uptake among undergraduates. Materials & Methods: A survey of undergraduates at the University of Nairobi's Main campus was conducted with a systematic selection of a sample using students class registers. Results: From 384 respondents, the study found that the uptake of coronavirus vaccine was positively correlated with COVID-19 saliency (r=0.211), skills and competency (r=0.146), behavioral intentions (r=0.159) and environmental factors (r=0.211). Conclusion: The uptake of COVID-19 vaccines among undergraduate students in Kenya is determined by all factors in the Integrated Model of Behavior Prediction such as vaccine saliency, behavioral intentions, environmental constraints and skills and competency. Therefore, increasing the uptake of COVID-19 vaccines among undergraduates may involve addressing all these factors.

Wearing mask in children: do's and don'ts

Due to COVID-19 disease, children of all ages seem susceptible to COVID-19;thus, preventing children from COVID-19 disease is a serious duty. One of the preventive strategies in children is the behavior of mask-wearing. Recently, many parents have stated concerns to doctors and social media about whether masks may be harmful for their children. Incorrect news about the negative effects of face masks has also been increasing. Therefore, this letter aims at answering the most common and most important parents' worries about children's wearing face masks.

UK street art and the meaning of masks during the COVID-19 pandemic, 2020-21

This paper contributes to social and cultural geographies of the COVID-19 pandemic through an exploration of the role of UK street art in documenting the remarkable shifts in the practice of wearing facemasks, the tensions and emotions involved, and the transformations in the meaning of facemasks during the pandemic. Street art has become an important outlet for political critique and social engagement, capturing the public mood in response to policies and recommendations attempting to stem viral transmission, including the requirement to wear facemasks in some public places. Drawing primarily on image analysis of street artworks produced during 2020 and sourced using online search tools, and qualitative interviews with UK street artists in 2020 and 2021, the paper first explores the changing geographies and politics of street art during the pandemic. It then examines the ways in which street art portrays mask-wearing simultaneously as reassuring, protective and fear-inducing, and reflects the meaning of masks in relation to protecting public health, managing anxieties concerning health risks, boosting morale, and symbolising solidarity and public spiritedness. The paper argues that pandemic street art contributes to public dialogue by articulating emotion and deeply held concerns, and communicating the intimate politics, semiotic meanings and social properties of objects associated with disease.

Analysis and prediction of the COVID-19 pandemic in Senegal using the SIR model

In this study, the mathematical SIR model (Susceptible-Infected-Recovered (cured and deceased)) was applied to the case of Senegal during the first two waves of the COVID-19 pandemic. During this period, from March 1, 2020, to March 30, 2021, the transmission and recovery rates as well as the number of reproduction were calculated and analyzed for the impact of the decisions taken by the Senegalese government. In both waves, the variation of the basic reproduction number as a function of time, with values below one towards the end of each study period, confirms the success of the Senegalese government in controlling the epidemic. The results show that the solution of mandatory mask-wearing is the best decision to counter the spread of the disease. Indeed, the mean number of reproduction is 2.11 in the first wave, and the second wave has a lower mean value of 1.23, while the decisions are less restrictive during this latter wave. Also, a short-term prediction model (about 4 months) was validated on the second wave. The validation criteria of this model reveal a good match between the results of the simulated model and the COVID-19 data reported via the Ministry of Health, Solidarity, and Social Action of Senegal.

The impact of face masks on COVID-19 transmission based on SEIADR model

In order to estimate the transmission of COVID-19, the asymptomatic class is introduced to the SEIADR model, an improved SEIADR model is proposed to analyze the influence of wearing face masks on the final size and the basic reproduction number of COVID-19. To study the impact of face masks on the transmission of COVID-19, the population is divided into two groups;one group wearing face masks (including susceptible, exposed, infectious, asymptomatic, dead and recovered), and the other not wearing face masks (including susceptible, exposed, infectious, asymptomatic, dead and recovered). The group dynamic model is used to determine the basic reproduction number and the control reproduction number of the epidemic. Then the final size of disease is simulated based on data. Finally, the dynamic influence of face masks on epidemic transmission is simulated by numerical analysis. Data simulations show that without any intervention, the basic reproduction number is 1.35. If 50% of population wear face masks, the susceptibility and infectivity are reduced by 50% 9 then the control reproduction number will decreased to 0.39, and the final epidemic size Will reduce from 73.20% to 16.15%.

Facemasks, material and metaphors: An analysis of socio-material dynamics of the COVID-19 pandemic

In 2020, not only did the Sars-Cov-2 virus become a global pandemic, but public life also changed in the wake of various infection control measures. Increased use of masks was one of the first clearly visible changes. With the masks came stories about masks. Who wore them, where people should wear them, and why? It quickly became clear, however, that stories about ‘the facemask' also have a metaphorical content, negotiating not only problems of the pandemic as a social crisis, but also other social issues amalgamated through the use of masks and the surrounding narratives. Thus, masks not only prevented infection, but also fed and materialised the public imaginary of the pandemic and its challenges. From this perspective, we explore three exemplary cases from Germany and Finland in 2020 in which the mask played different roles as a socio-material phenomenon, linking theoretical perspectives on materiality and metaphors. Additionally, the analysis presents illustrations done by a visual artist. These illustrations capture the key content of the analysis in the form of drawings. © The Author(s) 2023.

Breastfeeding and infection control measures among lactating COVID-positive mothers: a retrospective study

Background: Exclusive breastfeeding along with infection prevention measures is recommended for lactating COVID-positive mothers as benefits outweigh the risk. Aims and Objectives: The present study was undertaken to assess the feeding and infection prevention measures among the COVID-19 infected lactating mothers in Indira Gandhi Medical College and Research Institute, Puducherry to identify areas of concern. Materials and Methods: The cross-sectional and observational study was conducted by telephonic survey after verbal consent on a series of 103 COVID-positive postnatal mothers regarding their feeding practices and infection prevention measures. Descriptive statistics was used. Results: Breastfeeding was given by 72 (69.9%), mixed feeding by 27 mothers (26.2%), and formula feeds by four (3.9%). Overall, exclusive breastfeeding was given by 66 mothers (64.1%). With respect to infection prevention measures, high performance of frequent/always was observed for use of hand hygiene (n=90, 87.3%) and use of mask (n=81, 78.5%). Conclusion: Despite the pandemic situation, the most COVID-positive mothers breastfed their infants with fair compliance to infection prevention measures.

The implementation of COVID-19 health protocol: a higher students' perspective

Over two million Indonesians have been exposed to COVID-19. Every day, thousands of new confirmed cases continue to infect people and form local transmission, even though the guidelines for implementing health protocols in efforts against this pandemic have been rolled out. This study aims to reveal how COVID-19 health protocols are being implemented in Indonesia. We collected information from 289 students to observe the surrounding environment by distributing online questionnaires that include parameters for wearing masks and physical distancing. This study used a mix-method approach, in which the statistical and descriptive analysis were carried out sequentially. This study showed that the presence of positive cases does not affect the implementation of health protocols. Mann-Whitney's test also confirmed that there were no significant differences between the COVID-19 transmitted area and the green zone. This condition was caused by a lack of socialization, social exemplarity, mutual reprimand, and enforcement of the rules. The experience of people telling others to wear a mask has a low, significant, and positive correlation with the intensity of reprimanding others. This phenomenon shows that social awareness of implementing health protocols can continue to increase if they are accustomed to self-awareness. The implementation of the health protocol requires assessment to avoid inconsistencies that reduce the compliance of people.

Is France Once Again Looking for a Scapegoat?

On September 10, 2021, a special tribunal established by the French government launched an inquiry into the activities of former health minister Dr. Agnes Buzyn who was charged with "endangering the lives of others". It is surprising to learn of this accusation and inquiry into the actions of a public health official whose response to the epidemic was, to all appearances, exemplary.
