Novel Coronavirus

The novel Coronavirus (nCoV-19) pandemic began in Wuhan, China with Severe Acute Respiratory Syndrome (SARS) in December, 2019. The virus transmitted from China to other countries by traveling of the infected individuals. The number of infected populations with Coronavirus is increasing day by day with an increased mortality rate. The signs and symptoms of the disease include fever, non-productive cough, dyspnea, and fatigue. The transmission routes of the virus include respiratory secretions or droplet infection and direct contact with the infected person. Dentists are a group of professionals that are highly exposed to infectious diseases. The nCoV-19 is transmitted from patient to dentist and dentist to patient mainly through aerosol and splatter produced by the dental procedure and saliva of an infected person. To avoid transmission of the virus from patient to dentist and from dentist to other patients, screening tests should be done at dental setups. The use of gloves, face shields, masks, gowns, and antiseptic handwash are mandatory for the dentist. Awareness programs should be conducted to prevent further transmission of the disease. We searched Google, Google Scholar, WHO website for coronavirus and National Institute of Health website (nih.org.pk) for relevant literature by using various MeSH terms including ‘2019-nCoV’, ‘transmission of 2019-nCoV in dental clinics’, ‘dentistry and COVID-19’ and ‘infection control’, etcKey words: COVID-19, Dental clinics, Infection control, Transmission

Key Steps

One of the key steps in determining how to prevent the viral disease is to identify the virus. The virus lives in different ways and in different environments. It lives in the air, in the sea, on plants, animals and objects and humans. Some people put humans on the path of developing zoonotic diseases that are specific to animals but also involve people with unhealthy behaviors. In the food chain, each animal is hunted by other animals and feeds on other animals or plants and other objects. Bacteriophages are viruses that kill bacteria. And there are creatures that kill viruses and this is the biological struggle with viruses. When the virus enters the body, it performs a series of activities that lead to a series of symptoms in the patient. These symptoms include the behavior of viruses. These are among the ecological and behavioral characteristics of viruses that need to be fully understood in order to limit viruses and deal with epidemics and pandemics. In this study, we try to reach a conclusion by reviewing the articles that have information about the behavioral (signs and symptoms) and ecological characteristics of viruses and use these findings in order to combat viruses.

The Basic Reproduction Number

Abstract The aim of this study was to estimate the basic reproduction number (R0) of COVID-19 in the early stage of the epidemic and predict the expected number of new cases in Shahroud in Northeastern Iran. The R0 of COVID-19 was estimated using the serial interval distribution and the number of incidence cases. The 30-day probable incidence and cumulative incidence were predicted using the assumption that daily incidence follows a Poisson distribution determined by daily infectiousness. Data analysis was done using ‘earlyR’ and ‘projections’ packages in R software. The maximum-likelihood value of R0 was 2.7 (95% confidence interval (CI): 2.1−3.4) for the COVID-19 epidemic in the early 14 days and decreased to 1.13 (95% CI 1.03–1.25) by the end of day 42. The expected average number of new cases in Shahroud was 9.0 ± 3.8 cases/day, which means an estimated total of 271 (95% CI: 178–383) new cases for the period between 02 April to 03 May 2020. By day 67 (27 April), the effective reproduction number (Rt), which had a descending trend and was around 1, reduced to 0.70. Based on the Rt for the last 21 days (days 46–67 of the epidemic), the prediction for 27 April to 26 May is a mean daily cases of 2.9 ± 2.0 with 87 (48–136) new cases. In order to maintain R below 1, we strongly recommend enforcing and continuing the current preventive measures, restricting travel and providing screening tests for a larger proportion of the population.

Current Practices

Relegated to clinical afterthought, the topic of infection control has never taken center stage in our modern dental sedation and anesthesiology practices. Surgical and procedural masks, gloves, gowns, protective eyewear, and appropriate surgical attire have remained de rigueur in both fashion and custom for decades. However, the emergence of certain seminal events throughout health care history has driven mandated changes when practitioners, staff, patients, and the surrounding communities were exposed or put at risk of exposure to infectious disease. Hepatitis, human immunodeficiency virus, and now the global COVID-19 pandemic involving the novel coronavirus SARS-CoV-2, have forced us into rethinking our current practices. This review article will contextualize previous epidemics and their influence on infection control in dental settings, and it will explore the rapid evolution of current modifications to personal protective equipment and infection mitigation practices specific to sedation and anesthesia in dentistry.

Novel Coronavirus

Novel coronavirus (nCoV) is a novel form of virus with a new strain identified recently in humans. Common clinical signs and symptoms primarily consist of fever, cough, and breathing difficulties. In severe cases, it can results in pneumonia, severe acute respiratory syndrome, kidney failure, and even death. It is important to follow all infection control measures in prevention of the nCoV from spreading and controlling the epidemic situation. The risk of cross infection can be high between dental practitioners and patients due to the features of dental clinical settings. Here, we are summarizing the nCoV related information and infection control measures to be followed in dental practice.

<b>Background:</b> The novel coronavirus (COVID-19) pandemic is expected to last for an extended time, making strict safety precautions for office procedures unavoidable. The lockdown is going to be lifted in many areas, and strict guidelines detailing the infection control measures for aesthetic clinics are going to be of particular importance. <b>Methods:</b> A virtual meeting was conducted with the members (n = 12) of the European Academy of Facial Plastic Surgery Focus Group to outline the safety protocol for the nonsurgical facial aesthetic procedures for aesthetic practices in order to protect the clinic staff and the patients from SARS-CoV-2 infection. The data analysis was undertaken by thematic and iterative approach. <b>Results:</b> Consensus guidelines for nonsurgical facial aesthetic procedures based on current knowledge are provided for three levels: precautions before visiting the clinic, precautions during the clinic visit, and precautions after the clinic visit. <b>Conclusions:</b> Sound infection control measures are mandatory for nonsurgical aesthetic practices all around the world. These may vary from country to country, but this logical approach can be customized according to the respective country laws and guidelines.

Objective: to describe the occurrence of COVID-19 and the health services used by elderly individuals living by themselves; identify the knowledge held by elderly individuals regarding the transmission, signs and symptoms of COVID-19, as well as factors associated with poor knowledge of preventive measures according to sociodemographic and clinical variables. Method: cross-sectional survey conducted by telephone or mobile with 123 elderly individuals living by themselves in the Health Macro-Region of Triângulo Sul in the state of Minas Gerais, Brazil. Descriptive analysis was performed along with bivariate and multiple linear regression (p<0.05). Results: most elderly individuals did not present COVID-19 signs and symptoms (97.5%), were aware of how it is transmitted (86.6%), and of its signs and symptoms (90.8%). The elderly individuals were familiar with four preventive measures on average. After social distancing began, 85.7% of them left home and implemented three preventive measures on average, the most frequent of which was the use of face masks (99.0%). Being a man (p=0.001), 80 years old or older (p=0.045), and having fewer years of schooling (p=0.010) were associated with having less knowledge regarding the COVID-19 preventive measures. Conclusion: the elderly individuals were knowledgeable on COVID-19, but did not implement all the preventive measures. Male elderly individuals living by themselves with a low educational level are more vulnerable to COVID-19.

And Control

The novel coronavirus (covid-19) was initially identified at the end of 2019 and caused a global health care crisis. The increased transmissibility of the virus, that led to high mortality, raises the interest of scientists worldwide. Thus, various methods and models have been extensively discussed, so to study and control covid-19 transmission. Mathematical modeling constitutes an important tool to estimate key parameters of the transmission and predict the dynamic of the virus. More precisely, in the relevant literature, epidemiology is considered as a classical application area of branching processes, which are stochastic individual-based processes. In this paper, we develop a classical Galton-Watson branching process approach for the covid-19 spread in Greece at the early stage. This approach is structured in two parts, initial and latter transmission stages, so to provide a comprehensive view of the virus spread through basic and effective reproduction numbers respectively, along with the probability of an outbreak. Additionally, the effectiveness of control measures is discussed, based on a simple exponential smoothing model, which is used to build a non-mitigation scenario. Finally, our primary aim is to model all transmission stages through branching processes in order to analyze the first semiannual spread of the ongoing coronavirus pandemic in the region of Greece.

Novel Coronavirus

COVID-19, caused by infection of the novel coronavirus SARS-CoV-2, has caused a pandemic of enormous impact that has challenged healthcare and political system throughout the world. This new health emergency has occurred on top of the usual burden of diseases, including systemic sclerosis, and has led to many unanticipated consequences. An early consequence of the pandemic was postponement of the Sixth Systemic Sclerosis World Congress that was recently completed as a successful virtual congress with more than 1000 delegates. In this article, we summarise the relevance and impact of COVID-19 from the perspective of systemic sclerosis. Shared concepts of pathogenesis are considered, and the relevant literature emerging about COVID-19 and systemic sclerosis summarised. The specific impact of this pandemic on delivery of optimal scleroderma care is considered, together with the broader effect on rheumatic and musculoskeletal diseases and the activities of European League Against Rheumatism. As the World continues to struggle against this new infectious disease, it is notable that expertise and growing understanding of systemic sclerosis has been able to help tackle COVID-19. Moreover, the essential adjustments to deliver clinical care and establishment of new ways of working due to the pandemic have offered potential avenues for future improvement in systemic sclerosis care.
