An outbreak of new severe acute respiratory syndrome coronavirus disease, coronavirus disease 2019 (COVID-19), has emerged during December 2019. The ongoing outbreak in Wuhan City spread rapidly throughout China, where the fatality rate ranged from 2.1 to 4.9%. Due to its high transmissibility, the World Health Organization (WHO) declared a public health emergency of international concern on 30 January 2020. ⋯ The purpose of this article is to overview the history, epidemiology, clinical characteristics, diagnosis, and treatment of COVID 2019 reported in recently published studies. Based on the results of virus genome sequencing and a model of the interaction between host cells and the virus, we propose several possible targets for antiviral drugs, which may provide new ideas for epidemic control and vaccine development. Keywords: 2019 novel coronavirus; pneumonia; SARS-CoV-2; Coronaviridae; COVID-19.

In late December 2019, COVID-19, a new emerging disease, quickly spread in Wuhan, China. The WHO formally declared it a pandemic and a health emergency on March 11th, 2020. ⋯ The time to take leadership in healthcare where the national health system together with academic societies, universities and private initiative join forces to combat the pandemic has arrived. It is convenient to form collaboration groups of experts in the different specialties that through innovation in health and education, with evidence-based medicine, efficiency of operational costs and tools such as telemedicine, allow us to return to daily surgical procedures, reestablishing the surgery services as soon as possible.

Multicenter Study
Characteristics and outcomes of hospitalised patients with acute kidney injury and COVID-19.
COVID-19 has spread globally to now be considered a pandemic by the World Health Organisation. Initially patients appeared to have a respiratory limited disease but there are now increasing reports of multiple organ involvement including renal disease in association with COVID-19. We studied the development and outcomes of acute kidney injury (AKI) in patients with COVID-19, in a large multicultural city hospital trust in the UK, to better understand the role renal disease has in the disease process. ⋯ We have shown that the development of AKI is associated with dramatically worse outcomes for patients, in both mortality and the requirement for critical care. Patients with COVID-19 presenting with, or at risk of AKI should be closely monitored and appropriately managed to prevent any decline in renal function, given the significant risk of deterioration and death.

The COVID-19 pandemic and the fast global spread of the disease resulted in unprecedented decline in world trade and travel. A critical priority is, therefore, to quickly develop serological diagnostic capacity and identify individuals with past exposure to SARS-CoV-2. In this study serum samples obtained from 309 persons infected by SARS-CoV-2 and 324 of healthy, uninfected individuals as well as serum from 7 COVID-19 patients with 4-7 samples each ranging between 1-92 days post first positive PCR were tested by an "in house" ELISA which detects IgM, IgA and IgG antibodies against the receptor binding domain (RBD) of SARS-CoV-2. ⋯ Study of the antibody kinetics of seven COVID 19 patients revealed that while IgG levels are high and maintained for at least 3 months, IgM and IgA levels decline after a 35-50 days following infection. Altogether, these results highlight the usefulness of the RBD based ELISA, which is both easy and cheap to prepare, to identify COVID-19 patients even at the acute phase. Most importantly our results demonstrate that measuring IgG levels alone is both sufficient and necessary to diagnose past exposure to SARS-CoV-2.

Prevention is the best way to manage a pandemic like COVID-19. The World Health Organization has issued public advice to create awareness by providing people knowledge to prevent/protect them from COVID-19. Hence, the present study was planned to assess knowledge of prevention and its practical use amongst samples from the Saudi Arabian population. It can be used to bring awareness among the masses not only in expanding their knowledge about COVID-19 but also on how to enforce a practicing behavior in relation to the prevention of COVID-19. The study is among the pioneer studies on the issue related to knowledge and practice of the prevention of COVID-19 among Saudis and foreign nationals residing in Saudi Arabia. ⋯ Results reveal that there is a significant relationship between knowledge and practice, but the strength of association is weak. It was found that knowledge and practice of COVID-19 was followed differently in the five regions of Saudi Arabia and the level of education of the respondents influenced their choice of practice to protect themselves from the effects of COVID-19. The study has contributed in the body of literature by examining the inter-relationship between knowledge and practice and their use in prevention of COVID-19 among the Saudi population.
