The world evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-Cov2 or simply COVID-19) led the World Health Organization to declare it a pandemic. The disease appeared in China in December 2019, and it has spread fast around the world, especially in European countries like Italy and Spain. The first reported case in Brazil was recorded in February 26, and after that the number of cases grew fast. In order to slow down the initial growth of the disease through the country, confirmed positive cases were isolated to not transmit the disease. To better understand the early evolution of COVID-19 in Brazil, we apply a Susceptible–Infectious–Quarantined–Recovered (SIQR) model to the analysis of data from the Brazilian Department of Health, obtained from February 26, 2020 through March 25, 2020. Based on analytical and numerical results, as well on the data, the basic reproduction number is estimated to [Formula: see text]. In addition, we estimate that the ratio between unidentified infectious individuals and confirmed cases at the beginning of the epidemic is about 10, in agreement with previous studies. We also estimated the epidemic doubling time to be [Formula: see text] days.

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.

Abstract Coronavirus disease 2019, first reported in China in late 2019, has quickly spread across the world. The outbreak was declared a pandemic by the World Health Organization on March 11, 2020. Here, we describe our initial efforts at the University of Florida Health for processing of large numbers of tests, streamlining data collection, and reporting data for optimizing testing capabilities and superior clinical management. Specifically, we discuss clinical and pathology informatics workflows and informatics instruments which we designed to meet the unique challenges of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing. We hope these results benefit institutions preparing to implement SARS-CoV-2 testing.

With over 80 million cases, and 1,800,000 deaths reported at the end of 2020 by the World Health Organization, the “CoronaVirus Disease-2019” (CoViD-19) pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), should be viewed as a global catastrophe [...]

Coronavirus (COVID-19) was recognized in late December in Hubei province of Wuhan city in China. This highly contagious disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is transmitted from humans to humans. After the first case in Wuhan, the disease rapidly spread to other parts of the globe. On March 11, 2020, the World Health Organization (WHO) made an assessment that COVID-19 can be characterized as a pandemic. Thus, social-distancing became an important measure to stop the spread of this disease. Various countries across the world adopted nationwide lockdowns. This led to a completely new scenario for the world, where every business in each industry faced new challenges and witnessed new opportunities. Similarly, the medical personal protective industry, a vital part of the healthcare sector, also witnessed new growth opportunities.

In March 2020, the World Health Organization (1) declared COVID-19 as a pandemic and a threat to global public health (2). The virus mainly affects the lungs and can cause acute respiratory distress syndrome (ARDS). In addition, coronavirus 2 severe acute respiratory syndrome (SARSCOV2) also has devastating effects on other important organs, including the circulatory system, brain, gastrointestinal tract, kidneys and liver

In January 2020, the pathogen was identified and named by the World Health Organization as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2). The consequent SARS-CoV-2-related disease was defined as coronavirus disease 2019 (COVID-19). As data emerged about characteristics of the disease, it was found to be associated with increased risk of acute kidney injury (AKI). We explore the recent literature and reports emerging from the epicenters of the pandemic to help our viewers understand the nature of AKI among these patients.

The severe acute respiratory syndrome coronavirus 2 virus and its associated disease, called coronavirus disease 2019 (COVID-19), first appeared in Wuhan, China in December 2019 and quickly spread around the world. Coronavirus was officially named COVID-19 by the World Health Organization and was recognized as a pandemic due to its rapid spread worldwide. Based on the published data, it is hoped to provide a source for later studies and to help prevent and control the contagious COVID-19 and its characteristics, and considerations that surgeons and medical staff must observe during the epidemic.

We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2.

Recently, much of the world, including the World Health Organization, the European Union and many North American countries, have emphasized patient safety. Around the same time, Taiwan’s Department of Health (DOH) devoted a significant amount of resources to better the quality of medical treatment for their patients. This study explores perceptions of and attitudes towards patient safety among medical staff and patients in emergency departments. Analysis results indicate that medical staff and patients significantly differ in perceptions and attitudes. Results of this study provide a valuable reference for governmental authorities and hospital managers in formulating policies aimed at clarifying perceptions and attitudes regarding patient safety among medical staff and patients in emergency departments.
