To investigate CT images of 100 confirmed COVID-19 pneumonia patients to describe the lesion distribution, CT signs, and evolution during different courses. ⋯ • The course of COVID-19 pneumonia consists of three stages: 1~7 days is the early rapid progressive stage, 8~14 days is the advanced stage, and after 14 days, the abnormalities started to decrease. • In the early rapid progressive stage, GGO plus a reticular pattern, GGO plus consolidation, and GGO were all common signs; in the advanced stage, signs of progression and absorption coexisted; lung abnormalities showed an asynchronous process with parts with absorption and parts progressing. • Lung abnormalities mainly showed predominantly peripheral, middle, and lower distribution.

The rapid spread of SARS-CoV-2 leading to the COVID-19 pandemic with more than 400,000 deaths worldwide and the global economy shut down has substantially accelerated the research and development of novel and efficient COVID-19 antiviral drugs and vaccines. In the short term, antiviral and other drugs have been subjected to repurposing against COVID-19 demonstrating some success, but some excessively hasty conclusions drawn from significantly suboptimal clinical evaluations have provided false hope. On the other hand, more than 300 potential therapies and at least 150 vaccine studies are in progress at various stages of preclinical or clinical research. The aim here is to provide a timely update of the development, which, due to the intense activities, moves forward with unprecedented speed.

Understanding the consequence of COVID-19 on undergraduate medical education: Medical students' perspective.
The coronavirus disease 2019 pandemic has significantly influenced the normal operations of all human affairs on a global scale. Indeed, the pandemic has had a considerable impact on the delivery of medical education in the UK for both pre-clinical and clinical year students. In response to the escalating case fatality rate due to the pandemic, there has been widespread termination of clinical placements, face-to-face teaching sessions, and examinations that require a physical presence by UK medical schools. ⋯ Despite the resultant complications of the pandemic on medical education, these challenging times may present a serendipitous opportunity for medical students to cultivate the personal attributes expected of a doctor in the face of adversity. In light of the pandemic, there is scope to reconsider the effectiveness of current medical education and welcome innovative methods of delivering education whilst ensuring quality. The combination of recent telecommunication developments with current teaching methodologies may positively change the future landscape of medical education.
