Novel Coronavirus

A series of cases of pneumonia occurred in China in late 2019. For this type of coronavirus, the WHO formally identified the condition as a coronavirus disease 2019 (COVID-19). They announced that this disease is the recent main concern of health problems in the world. Transfer of this novel coronavirus (nCoV) from human to human exists predominantly among family members, who have close contact with each other. This review article is provided based on the recent findings of COVID-19, which were retrieved by searching PubMed, Google Scholar, Scopus, and Web of Science until December 2020. Here, we highlighted the coronaviruses types, COVID-19 symptoms, epidemiology of the disease, transmission ways, and nCoV related pneumonia pathogenesis and continue with characteristic features and treatment methods. While no approved treatments are available for this type of infection therapy but several drugs may have potential benefits. It seems that identifying the detailed characteristics of the novel coronavirus disease offers the foundation for further research into the production of effective anti-COVID-19 drugs and vaccines.

The novel coronavirus disease 2019 (COVID-19) pandemic has brought to light the role of environmental hygiene in controlling disease transmission. Healthcare facilities are hot spots for infectious pathogens where physical distancing and personal protective equipment (PPE) are not always sufficient to prevent disease transmission. Healthcare facilities need to consider adjunct strategies to prevent transmission of infectious pathogens. In combination with current infection control procedures, many healthcare facilities are incorporating ultraviolet (UV) disinfection into their routines. This review considers how pathogens are transmitted in healthcare facilities, the mechanism of UV microbial inactivation and the documented activity of UV against clinical pathogens. Emphasis is placed on the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as well as multidrug resistant organisms (MDROs) that are commonly transmitted in healthcare facilities. The potential benefits and limitations of UV technologies are discussed to help inform healthcare workers, including clinical studies where UV technology is used in healthcare facilities.

Novel Coronavirus

SARS-COV2 virus causes Coronavirus disease (COVID-19) and represents the causative agent of a potentially fatal disease that is of great global public health concern. The novel coronavirus (2019) was discovered in 2019 in Wuhan, the market of the wet animal, China with viral pneumonia cases and is life-threatening. Today, WHO announces COVID-19 outbreak as a pandemic. COVID-19 is likely to be zoonotic. It is transmitted from bats as intermediary animals to human. Also, the virus is transmitted from human to human who is in close contact with others. The computerized tomographic chest scan is usually abnormal even in those with no symptoms or mild disease. Treatment is nearly supportive; the role of antiviral agents is yet to be established. The SARS-COV2 virus spreads faster than its two ancestors, the SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV), but has lower fatality. In this article, we aimed to summarize the transmission, symptoms, pathogenesis, diagnosis, treatment, and vaccine to control the spread of this fatal disease.

Abstract Background COVID-19 has been giving the devastating impact on the current medical care system. There are quite many guidelines on COVID-19, but only a few on the management of hepatocellular carcinoma (HCC) during COVID-19 pandemic. Aims We develop these recommendations to preserve adequate clinical practice for the management of HCC. Methods Experts of HCC in the Asia–Pacific region exchanged opinions via webinar, and these recommendations were formed. Results Close contact should be minimized to reduce possible exposure of both medical staff and patients to the novel coronavirus. To prevent transmission of the virus, meticulous hygiene measures are important. With the decrease in regular medical service, the medical staff may be mobilized to provide COVID-19-related patient care. However, diagnosis and treatment of HCC should not be delayed because of COVID-19 pandemic. The management of HCC should be the same as in non-pandemic circumstances. HCC is highly malignant, thus it is recommended not to delay curative treatment such as surgery and ablation. However, a kind of triage is necessary even among patients with HCC when resources are insufficient for all to be treated. Curative treatments should be periodized and cytoreductive or non-curative treatment such as vascular interventions and systemic therapy may be postponed until it can be performed safely with sufficient resources. For patients with confirmed or suspected to be infected with the novel coronavirus, diagnosis and treatment should be postponed until the virus is eliminated or they are confirmed as not being infected with it. Conclusions These are collection of measures implemented by front-line medical professionals. We would evolve these recommendations over time as more real-world data becomes available.

The outbreak of coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is declared pandemic by World Health Organization (WHO) keeping in view its infection rate and toxicity level. The entire world is struggling hard to survive the prevailing health emergency. The authors realise the urgent need of contributing an overview of the present scenario to the researchers who are breathlessly trying to combat this pandemic situation. This review aimed at binding all the scattered data and research available till now on COVID-19 disease starting from its origin to transmission and spread through environmental factors till treatment and the safety measures that should be implemented. This article would possibly help the readers by providing an outlook of current scenario on various perspectives of COVID-19 disease at a single glance. The types, origin and toxicity caused are discussed in brief. The role of contaminated aerosols (viral-laden smoke from tobacco, cigarettes), wastewater, fomites, human and faecal matter are important in spreading the novel coronavirus in the environment. There is no specific treatment till date but clinical trials and diagnosis on several known drugs are on-going. The precaution and safety measures could hopefully reduce number of infections and mortality. The number of infected cases confirmed till 2 August 2020 was 17660523 with 680894 deaths in the world. We tried in this review article to summarize the scattered data available on biochemistry of SARS-CoV-2, environmental spread of virus and the safety measures to combat COVID-19 pandemic.

Abstract Background: COVID-19 is a newly emerging disease caused by a novel coronavirus (SARS-CoV-2), which spread globally in early 2020. Asymptomatic carriers of the virus contribute to the propagation of this disease, and the existence of asymptomatic infection has caused widespread fear and concern in the control of this pandemic.Methods: In this study, we investigated the origin and transmission route of SARS-CoV-2 in Anhui’s two clusters, analyzed the role and infectiousness of asymptomatic patients in disease transmission, and characterized the complete spike gene sequences in the Anhui strains.Results: We conducted an epidemiological investigation of two clusters caused by asymptomatic infections sequenced the spike gene of viruses isolated from 12 patients. All cases of the two clusters we investigated had clear contact histories, both from Wuhan, Hubei province. The viruses isolated from two outbreaks in Anhui were found to show a genetically close link to the virus from Wuhan. In addition, new single nucleotide variations were discovered in the spike gene.Conclusions: Both clusters may have resulted from close contact and droplet-spreading and asymptomatic infections were identified as the initial cause. We also analyzed the infectiousness of asymptomatic cases and the challenges to the current epidemic to provided information for the development of control strategies.

Background. The novel coronavirus (SARS-COV-2) and related syndrome (COVID-19) has required a worldwide measure of quarantine with severe consequences for millions of people. Methods. Since psychopathological consequences related to social restrictions have been reported, a systematic review according to Cochrane Collaboration guidelines and the PRISMA Statement was performed to quantify the effects of quarantine on mental health of adults. Major databases - Pubmed, Scopus, Embase, PsycInfo, and Web of Science- were researched for observational studies with data on mental health indexes related to quarantine or isolation for epidemic infections. Results. Twenty-one independent studies were included for 82,312 subjects. Conclusions. The results showed that at least 20% of people exposed to these conditions reported a psychological distress, with a prevalence of PTSD, depression and, less often, generalized anxiety. Important methodological bias weakens the conclusion of most studies, opening to the need of further research on mental health after quarantine and related risk/buffering factors.

Transmission Of Disease

COVID-19 (Novel coronavirus or corona disease is spreading continuously all over the world. Overloading of ICU and health care system capacity. Along with age factor, community spread, vertical transmission of disease and clinical manifestation is the risk factor for the poor outcomes. The transmission is mainly through respiratory droplets when individual sneezes or coughs and also due to the close contact with an infected individual. Every researcher is in found of preventive measure, and in found of effective treatment for it. As the population is rushing to keep themselves protected from the infection, Ayurveda practitioners are in stress that the kalpas cited in Ayurveda literature will be helpful in strengthening the immunity and to fight against COVID-19. It is an attempt to study the Novel Coronavirus (COVID-19) it's clinical diagnostic and management in Ayurveda perspective. Various Samhitas, such as Charaka Samhita, Ashtanga Hridaya, Madhava Nidana  articles were referred for this study. According to Ayurveda literature, a unique method of impending a fresh identified illness Rather than centring on the bacteriological etiology, Ayurveda encirclements a universal skill for particularising the details of the illness at hand. Till the date, no vaccination is being found for COVID-19 yet, but the concepts given in Vedas have information about diagnostic and management. This attempt is to encourage Ayurveda  practitioners and young researcher’s to work on the formulations, which are cited thousands of years ago to breakdown the pathology of disease and work for the development and promotion of Ayurveda.
