Face masks play a pivotal role in the control and prevention of respiratory diseases, such as the novel coronavirus (COVID-19). Despite their widespread use, it is not known how face masks affect human social interaction. In this behavioral economics study (N = 475), we examined how mask-wearing modulates individuals’ likelihood of acceptance of unfair monetary offers in an iterated social exchange. Overall, participants accepted more offers, including more unfair offers, from mask-wearing opponents than from opponents without a mask. This effect was enhanced when participants ascribed more altruistic motives to their interaction partner. Importantly, this pattern of results was only present for surgical face masks, but not when a non-medical cloth face covering was used. This is the first study to uncover a new phenomenon, the face-mask effect, in which face masks can alter human social behavior.

Novel Coronavirus

A face mask is a loose-fitting, disposable outfit that acts as a physical barrier between the mouth and nose of an individual and the potential pollutants in the surrounding environment. COVID-19 which is also called as 2019-nCov is caused by the novel coronavirus and it is spread by the salivary droplets or nasal discharge released when an infected person coughs or sneezes. In the current COVID -19 scenario, the face mask is designed to ameliorate the prevention of airborne transmission of the novel coronavirus. The use of face mask is competent only when the other personal preventive measures are ideally pursued. The effectiveness of the use of face mask depends strongly on the do’s and don’ts which has to followed while wearing a face mask. The purpose of this study is to analyze and summarize the published literature associated with the types, usage, risks, limitations, disposal and reusability of face mask. The availability of medication and treatment options are sparse and the development of vaccines for COVID-19 is going to take a longer time. Hence the most effective strategy to curb the spread of the disease is by the judicious use of face mask along with other personal protective measures.

As the novel coronavirus (COVID-19) pandemic continues to expand, policymakers are striving to balance the combinations of nonpharmaceutical interventions (NPIs) to keep people safe and minimize social disruptions. We developed and calibrated an agent-based simulation to model COVID-19 outbreaks in the greater Seattle area. The model simulated NPIs, including social distancing, face mask use, school closure, testing, and contact tracing with variable compliance and effectiveness to identify optimal NPI combinations that can control the spread of the virus in a large urban area. Results highlight the importance of at least 75% face mask use to relax social distancing and school closure measures while keeping infections low. It is important to relax NPIs cautiously during vaccine rollout in 2021.

Abstract: The danger of the novel coronavirus has not yet come to an end, and new variants have begun to attack the world. What philosophy should humankind’s strategy be based on when human society as a group is fighting against Covid-19, as the pandemic ravages the world? Unfortunately, political leaders of various countries have failed to achieve the overall awareness of attacking the pandemic for a shared future for mankind so far. In the face of the pandemic, mankind as a whole urgently needs to break through the narrow nation-oriented ideology of seeking only self-protection. The International Community should establish a new type of international cooperation featuring the concept of harmony of "all things under heaven as a unity". The international relations system dominated by the power ofwestern discourse is now in a bottleneck. The main aim of this article is to study the ancient Chinese wisdom of "the Unity of Man and Heaven" philosophy and build a global harmonious community. The author argues that the “export” of the aforementioned wisdom must be a priority for Chinese scholars. Keywords: Tao; Unity of Man and Heaven; Novel Coronavirus; Anthropocentrism; Harmony.

In less than a year, the novel coronavirus rapidly changed the world scenario. To dealing with the fast spread of the disease, health associations coordinate data flows and issue guidelines to better mitigate the impact of the threat. Also, scientific groups around the world are working to ensure that all information about the mechanisms of the virus, transmission, and disease clinics is updated as the disease progresses. The objective of this study was to present the guidelines and recommendations for preventing, management strategies, clarifications about pandemics disinformation, and diagnosing COVID-19 infection in human specimens adopted from the main health centers and institutions in the world, such as WHO and Centers for Disease Control and Prevention (CDC). It is important to highlight that the rapid and effective enforcement of existing international and national action plans, as well as parallel review and improvisation, is facilitating the affected countries to contain transmission and possibly delay the peak of outbreak and mortality.

Summary. The first known case of infection from the novel coronavirus was recorded almost one year ago, in China’s Hubei province. The city of Wuhan was infamous the world over as the original virus epicenter, seeing more than half of China’s reported cases and deaths. The outbreak of COVID-19 virus, as sickened more than 14.7 million people. At least 610.200 people have died. The aim of the study – to analyze and systematize the literature data about the influence of chronic diseases on the manifestation of COVID-19 infection. Materials and Methods. The study uses publications of the world scientific literature on COVID-19 infection, in particular the causes and mechanisms of its development, treatment, complications and its consequences as well as the influence of different chronic disorders on the course of COVID-19. Results. A sample of patients hospitalized with COVID-19 across 14 states of the USA in March was analyzed by The Centers for Disease Control and Prevention. It was found that many (89 %) had underlying health problem and 94 % of patients were at the age 65 and older. The case fatality rate for those under age 60 was 1.4 percent. For those over age 60, the fatality rate jumps to 4.5 percent. The older the population, the higher the fatality rate. For those 80 and over, Covid-19 appears to have a 13.4 percent fatality rate. Moreover, it was recognized, that older adults don't present in a typical way of the course of different disorders, and we're seeing that with Covid-19 as well. Conclusions. Chronic diseases and conditions are on the rise worldwide. COVID-19 became the most challenging pandemic influencing all countries worldwide. Chronic diseases are suggested to be one of the main causes of different life-threatening complications of COVID-19 infection and one of the main factors of poor prognosis for the patients.

A novel coronavirus has spread over the world and has become an outbreak. This, according to a WHO report, is an infectious disease that aims to spread. As a consequence, taking precautions is the only method to avoid catching this virus. The most important preventive measure against COVID-19 is to wear a mask. In this paper, a framework is designed for face mask detection using a deep learning approach. This paper aims to predict a person having a mask or unmask and also presents a proposed dataset named RTFMD (Real-Time Face Mask Dataset) to accomplish this objective. We have also taken the RFMD dataset from the internet to analyze the performance of system. Contrast Limited Adaptive Histogram Equalization (CLAHE) technique is applied at the time of pre-processing to enhance the visual quality of images. Subsequently, Inceptionv3 model used to train the face mask images and SSD face detector model has been used for face detection. Therefore, this paper proposed a model CLAHE-SSD_IV3 to classify the mask or without mask images. The system is also tested at VGG16, VGG19, Xception, MobilenetV2 models at different hyperparameters values and analyze them. Furthermore, compared the result of the proposed dataset RTFMD with the RFMD dataset. Additionally, proposed approach is compared with the existing approach on Face Mask dataset and RTFMD dataset. The outcomes have obtained 98% test accuracy on this proposed dataset RTFMD while 97% accuracy on the RFMD dataset in real-time.

There is a need to evaluate and minimise the risk of novel coronavirus infections at mass gathering events, such as sports. In particular, to consider how to hold mass gathering events, it is important to clarify how the local infection prevalence, the number of spectators, the capacity proportion, and the implementation of preventions affect the infection risk. In this study, we used an environmental exposure model to analyse the relationship between infection risk and infection prevalence, the number of spectators, and the capacity proportion at mass gathering events in football and baseball games. In addition to assessing risk reduction through the implementation of various preventive measures, we assessed how face-mask-wearing proportion affects infection risk. Furthermore, the model was applied to estimate the number of infectors who entered the stadium and the number of newly infected individuals, and to compare them with actual reported cases. The model analysis revealed an 86%-95% reduction in the infection risk due to the implementation of face-mask wearing and hand washing. Among the individual measures, face-mask wearing was particularly effective, and the infection risk increased as the face-mask-wearing proportion decreased. A linear relationship was observed between infection risk at mass gathering events and the infection prevalence. Furthermore, the number of newly infected individuals was also dependent on the number of spectators and the capacity proportion independent of the infection prevalence, confirming the importance of considering spectator capacity in infection risk management. These results highlight that it is beneficial for organisers to ensure prevention compliance and to mitigate or limit the number of spectators according to the prevalence of local infection. Both the estimated and reported numbers of newly infected individuals after the events were small, below 10 per 3-4 million spectators, despite a small gap between these numbers.

: New and fascinating physical, chemical and biological phenomena arise in ultra-small materials, such as graphene. Graphene is a single layer formed only for carbon atoms, super-strong, 200 times stronger than steel and as much as 6 times lighter. It also has a high elasticity and density. Furthermore, it seems to be impermeable to almost everything, but it allows the passage of water and air. Due to its versatility, modern and urgent applications arise every day, one of the most necessary, currently, is the control of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), the virus responsible for the novel coronavirus disease (COVID-19), which has dimensions around 100 nm and has caused a worldwide public health emergency. Different ways to prevent coronavirus contagion has been proposed and one of them is through the use of masks. Here, we investigated some properties of graphene that can help combat COVID-19. A scale appropriate for comparison shows that the spatial dimension of a virus is much larger than the graphene sheet, making it a great candidate for manufacturing face masks, filters and respirators. We also make use of first-principles calculations, based on the density functional theory (DFT), to investigate the interaction between graphene and a water molecule. We observed that the water molecule undergoes a repulsion force when it is very close to the graphene sheet. The hydrophobicity of graphene can be important to prevent the face mask that doesn’t get wet when you breathe with it.

The novel Coronavirus disease (COVID-19) first appeared in December 2019 in Wuhan, Hubei Province China before emerging in neighbouring countries in early 2020. The World Health Organization (WHO) declared COVID-19 a pandemic when the spreading of the virus started accelerating in many parts of the world and killing thousands of people. As of 22nd May 2021, there were more than 166 million confirmed cases with more than 147 million recovered and nearly 3.5 million deaths (Worldometers, n.d.). According to the WHO (2020) and Centers for Disease Control and Prevention (2020), the virus easily spreads through coughing and sneezing. Therefore, many countries implemented social distancing between individuals and various other restriction orders or recommendations (e.g., stay-at-home policies, closure of non-essential businesses) to help curb virus spread. How governments in each country reacted to control the spread of the virus appeared crucial to mitigate public health and economic impacts.
