The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) which caused COVID-19, is a pandemic that threatens human societies in many ways. It seems that the main strategy of managing coronavirus at present is to prevent infection. In addition to improving physical fitness, moderate-intensity exercise boosts the cellmediated and humoral immune system responses, especially in people with weakened immune systems who are at risk of coronavirus implications such as the elderly, obese people and those with chronic diseases. Therefore, performing regular exercise during life span can be considered as an effective strategy to prevent viral diseases such as COVID-19. On the other hand, home quarantine and non-use of public sports setting reduce physical fitness, circadian rhythm disturbances, sleep disturbances, depression, increased sedentary behaviors and impair the balance of energy received and consumed, which leads to a weakened immune system and a more severe risk of complications from COVID-19 disease. Performing moderate-intensity exercise at home during an outbreak can be an effective strategy in counteracting these complications. In addition, moderateintensity exercise is effective in improving the immune system and counteracting the effects of coronavirus directly by enhancing the immune system, antioxidant defenses and anti-inflammatory responses, and as well as indirectly by reducing anxiety, improving mood and modulating fat profile and insulin sensitivity.

In December 26, 2019, 4 unusual cases of pneumonia were recorded in China, three of those were from the same family. Another 3 cases of pneumonia were found in the same hospital in December 28 and 29(1). The virus started to expand rapidly so that doctors in Wuhan Hospital reported the phenomenon to China’ s CDC and WHO. The research articles began to publish online from the first of January. The Coronavirus news spread out as quickly as the virus. The virus was named new coronavirus 2019 (nCoV 2019). In January 7, 2020 the disease caused by the virus was identified as CoVID 19 (1). The altmetrics database indicates the first mentions to the peer reviewed articles about coronavirus has been tracked in social media like Twitter and Facebook since January 16, 2020. The majority of mentions aggregated from the public profiles. The scientists, practitioners (like doctors) and science communicators (like journalists) were the other group of people who mentioned the scientific articles. This could be a dangerous sign for risk communication, at the same time. The public are the main group who follow the news and information on the social media but not all of the public know how to distinguish misinformation from the truth....

The new coronavirus, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes an infectious disease called coronavirus disease 19 (COVID-19). This disease is highly contagious, and it damages organs due to the high affinity of Spike protein for the human angiotensin-converting enzyme 2 (ACE2) cell receptor, which is highly expresses in organs such as the lungs, heart, liver, kidneys, brain, and bladder. These organs seems a probable host for the virus although the main target tissue of the virus is the lungs. In general, the virus enters the host cell by Spike protein, which it is a good candidate for the vaccine design. Inhibition or blockade of ACE2 receptors using antibodies that neutralize this receptor can be a hope to prevent the virus from invading the cell and causing damage.

On the threshold of 2020,the world was faced with a dangerous and pervasive phenomenon called the coronavirus or Covid-19. The virus led to severe damage to private individuals and legal entities. In addition to various social, cultural, and economic dimensions, it also has legal aspect. In the present study, an attempt has been made to explain the various aspects of civil liability of private individuals resulting from the coronavirus and the factors that relieve individuals of responsibility by examining Imamiyah jurisprudence and domestic law. In jurisprudential and legal sources, several principles have been considered for the civil liability of individuals, including waste, causation, harmlessness and premonition, and so on. The people are responsible not only intentionally but also for any negligence in following the medical instructions in a situation where we face the risk of Corona epidemic in the country. But in some circumstances, responsibility can be transferred from the transferor according to jurisprudential rules such as charity and action.

Coronavirus disease-2019 (COVID-19) is a type of acute viral pneumonia, which began with a sudden outbreak in Wuhan, China. Although closely related to severe acute respiratory syndrome, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), the disease excessive transmission rate distinguishes it from other viral pneumonia diseases. The pulmonary complications and infections caused by this virus, as well as the lack of specific therapeutic have caused one of the most complicated epidemics of the last century. In this review article, we attempted to discuss and describe the latest findings of immunopathogenesis, as well new and applicable treatments for coronavirus disease.

Background: Scientometrics studies are one of the most efficient methods of quantitative evaluation of the scientific outputs of valuable information and citation databases for understanding and observing the status of scientific publications in different subject areas. The main aim of this article was to study the 50 years of Coronavirus scientific publications in the world. Materials & Methods: This applied research was carried out using scientometrics methods and an analytical approach. The statistical population of this article includes 5128 Coronavirus subject area documents indexed on the WoS from 1970 to 2019. The keywords were extracted from MeSH and analyzed using Excel 2016. Results: Data analysis showed that the highest science production was in 2005, and the highest citation number was in 2019. “ Enjuanes L. ” is the most proliferated author, the United States, the most productive country, and the University of Hong Kong, the top organization in Coronavirus in the last half-century. Conclusion: The results showed, there is a direct relationship between the Coronavirus outbreaks and the amount of Scientific Publications in this area in the World. The quality of the researchers' productions in this area can be deliberated by scientific methods and researchers' self-citation has affected their h-index. For health care researchers, policymakers, and planners, it is necessary to be aware of the results of scientific studies of strategic and vital research areas, such as Coronavirus, to identify more appropriate therapeutic goals, make better decisions, and provide more effective solutions in the shortest time.
