The World Health Organization (WHO) on March 11, 2020, has declared the novel Corona virus (COVID-19) outbreak a global pandemic. It is essential to understand how coronavirus transmits from one person to another and this knowledge will help protect the vulnerable and limit the spread of the Corona virus. The mode of respiratory transmission of Corona virus is not completely understood as of date. Using a computer simulation, this paper analyses the probability of spreading of Corona virus through air among the people who are standing in a queue. The parameters such as the diameter of the virus particle, room temperature, relative humidity, height of the person, distance between the people and the waiting time in the queue are considered in the computer model to determine the distribution of Corona virus and hence identify the risk factor of spreading the Covid-19. This paper describes the possibilities of getting infectious when a Covid-19 infected person present in a queue and the impact on the waiting time and the position in the queue on the transmission of Corona virus.

Abstract Background: The coronavirus disease 2019 (COVID-19) has been declared a global pandemic by the World Health Organization. Patients with cancer are more likely to incur poor clinical outcomes. Due to the prevailing pandemic, we propose some surgical strategies for gastric cancer patients. Methods: The ‘COVID-19’ period was defined as occurring between 2020-01-20 and 2020-03-20. The enrolled patients were divided into two groups, pre-COVID-19 group (PCG) and COVID-19 group (CG). A total of 109 patients with gastric cancer were enrolled in this study. Results: The waiting time before admission increased by 4 days in the CG (PCG: 4.5 [IQR: 2, 7.8] vs. CG: 8.0 [IQR: 2,20]; p=0.006). More patients had performed chest CT scans besides abdominal CT before admission during the COVID-19 period (PCG: 22 [32%] vs. CG: 30 [73%], p=0.001). After admission during the COVID period, the waiting time before surgery was longer (PCG: 3[IQR: 2,5] vs. CG: 7[IQR: 5,9]; p<0.001), more laparoscopic surgeries were performed (PCG: 51[75%] vs. CG: 38[92%], p=0.021), and hospital stay period after surgery was longer (7[IQR: 6,8] vs.9[IQR:7,11]; p<0.001). In addition, the total cost of hospitalization increased during this period, (PCG: 9.22[IQR:7.82,10.97] vs. CG: 10.42[IQR:8.99,12.57]; p=0.006). Conclusion: This study provides an opportunity for our surgical colleagues to reflect on their own services and any contingency plans they may have to tackle the COVID-19 crisis.


The Novel Corona virus is emerging as a Global public health threat. The outbreak initially emerged in Wuhan, China, large numbers of patients were getting sick because of Pneumonia and later it was found that they were nfected with the Novel Corona virus this emphasizes the importance of analyzing the data of this virus and predicting their risks of infecting people all around the globe. In this study, we present an effort to compile and analyze the outbreak information on COVID19 based on the open datasets on 2019 nCoV provided by the Johns Hopkins University, World Health Organization. An exploratory data analysis with visualizations has been made to understand the number of different cases reported (confirmed, death, and re-covered) in the World. Overall, at the outset of an outbreak like this, it is highly important to readily provide information to begin the evaluation necessary to understand the risks and begin containment activities.

Among disparate infectious diseases viral infection in particular challenges survival of mankind across the globe. By superseding those events, 2019 novel (CoVID-19) or SARS-CoV-2 has become a new human health crisis threatening the world. Corona viruses (CoV) are large family of viruses that affects birds and mammals. In humans, Corona virus can cause respiratory tract infection ranging from the common cold to more serious infection such as SARS (Severe acute respiratory syndrome), MERS (Middle East Respiratory Syndrome) and CoVID-19 (Corona Virus Disease 2019) which can also become lethal. The Novel corona virus (CoVID-19) originated in 2019, is a novel virus which has not been identified in humans since past. At present, the source of CoVID-19 is not known. Although the infection is presumed to be in origin, person to person transmission is evident. Many supportive and symptomatic therapies where being carried out by the Medical practitioners as per the instructions of World Health Organization (WHO) with a hypothesis and there is no evidence that it works against CoVID-19. best to lower the current crises of infection is prevention and many measures that boosts the immunity are following by the people as directed by the Ministry of AYUSH.

Abstract Spread of the novel coronavirus SARS-CoV-2 has resulted in a global pandemic that is affecting the health and economy of all World Health Organization [WHO] regions. Clinical and translational research activities have been affected drastically by this global catastrophe. In this document we provide a suggested roadmap for resuming gastrointestinal translational research activities, emphasising physical distancing and use of personal protective equipment. We discuss modes of virus transmission in enclosed environments [including clinical workplaces and laboratories] and potential risks of exposure in the endoscopy environment for research staff. The proposed guidelines should be considered in conjunction with local institutional and government guidelines so that translational research can be resumed as safely as possible.

In March 2020, the World Health Organization announced that the new Corona virus is a global pandemic. The World Health Organization and the public health authority of various countries are working to contain the spread of the virus through quarantine. But these crises raise the level of stress and psychological tension on individuals and society. As well as Algeria is not an exception and this research will be on the extent of the impact of the pandemic on the conduct of lessons at the universities level in Algeria, which were not equipped for such situations during the outbreak of the emerging corona virus, and try to analyze the situation and then proposing some solutions that can work if it hurts humanity and the Algerians, especially an epidemic like the Corona virus pandemic (COVID-19).

The spread of the corona virus or better known as covid-19 in Indonesia is a serious matter that needs to be dealt with immediately considering the number of victims caused by the virus that was first discovered in Wuhan. As in mid-March, after the first death in Indonesia due to the corona virus and the designation of the catastrophic virus as a global pandemic by WHO or the World Health Organization, this indicates that the government must be tougher in controlling corona virus transmission in Indonesia. Even since March 15, 2020 Indonesia has determined the status of the co-19 distribution as a national disaster. The implications of the outbreak of the pandemic are the impact on problems both in the health and economic fields. In connection with health issues, the Indonesian government itself has established a public health emergency as stated in the Decree of the Head of the National Disaster Management Agency. This is as stated in Article 10 of Law Number 6 Year 2018 on Health Outrageousness as seems to be a lockdown consideration, there are large-scale social restrictions which are clearly evident in article 59 paragraph (2) which includes the consolation of schools and workplaces, restrictions on religious activities and / or restrictions on activities at public places or facilities.

A novel, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes severe acute respiratory syndrome and spread globally from Wuhan, China. In March 2020 the World Health Organization declared the SARS-Cov-2 virus as a COVID- 19, a global pandemic. This pandemic happened to be followed by some restrictions, and specially lockdown playing the leading role for the people to get disassociated with their personal and social schedules. And now the food is the most necessary thing to take care of. It seems the new challenge for the individual is self-isolation to maintain themselves on the health basis and fight against the pandemic situation by boosting their immunity. Food organised by proper diet may maintain the physical and mental health of the individual. Ayurveda aims to promote and preserve the health, strength and the longevity of the healthy person and to cure the disease by properly channelling with and without Ahara. In Ayurveda, diet (Ahara) is considered as one of the critical pillars of life, and Langhana plays an important role too. This article will review the relevance of dietetic approach described in Ayurveda with and without food (Asthavidhi visheshaytana & Lanhgan) during COVID-19 like a pandemic.

: The current global pandemic outbreak of a novel type of corona virus termed by World Health Organization as COVID-19 became an grave concern and worry to human health and world economy. Intense research efforts are now underway worldwide to combat and prevent the spread of this deadly disease. This zoonotic virus, a native to bat population is most likely transmitted to human via a host reservoir. Due to its close similarity to previously known SARS CoV (Severe Acute Respiratory Syndrome Corona Virus) of 2002 and related MERS CoV (Middle East Respiratory Syndrome Corona Virus) of 2012, it is also known as SARS CoV2. But unlike them it is far too infectious, virulent and lethal. Among its various proteins, the surface spike glycoprotein “S” has drawn significant attention because of its implication in viral recognition and host-virus fusion process. A detail comparative analysis of “S” proteins of SARS CoV (now called SARS CoV1), SARS CoV2 (COVID-19) and MERS CoV based on structure, sequence alignment, host cleavage sites, receptor binding domains, potential glycosylation and Cys-disulphide bridge locations has been performed. It revealed some key features and variations that may elucidate the high infection and virulence character of COVID-19. Moreover this crucial information may become useful in our quest for COVID-19 therapeutics and vaccines.
