Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has caused a worldwide pandemic and poses a serious public health risk. It has been proven that lung ultrasound can be extremely valuable in the diagnosis and treatment of the disease, which could also minimize the number of exposed healthcare workers and equipment. Because healthcare workers in ultrasound departments are in close contact with patients who might be infected or virus carriers, it is extremely important that they be provided sufficient protection. Extremely aggressive protection should be avoided because it might lead to a lack of protection equipment for the hospital. Guidance on proper protection management should be provided in detail, for example, how to choose personal protective equipment, how to disinfect the environment. To address these problems, on behalf of the Chinese Ultrasound Doctors Association, Chinese PLA Professional Committee of Ultrasound in Medicine, Beijing Institute of Ultrasound in Medicine and Chinese Research Hospital Association Ultrasound Professional Committee, the authors have summarized the recommendations for effective protection according to existing hygienic standards, their experience and available literature. After the recommendations were completed, two online conferences were held on January 31, 2020 and February 7, 2020, at which the recommendations were discussed in detail. A modified version of the work was circulated and finally approved by all authors, and is the present Chinese Expert Consensus on Protection for Ultrasound Healthcare Workers against COVID-19.

BAckground Severe COVID-19 patients account for most of the mortality of this disease. Early detection of severe cases of the disease remains a major challenge. Here, we performed clinical and laboratory profiling of COVID-19 to explore the early warning indicators of severe cases.Methods An analysis of the evolution during the hospitalization of clinical and laboratory findings from 78 confirmed COVID-19 patients and the associated risk factors.Results Of the 78 patients who were classified as un-severe at admission, 60 patients(stable group) were stable as mild cases until discharge, and the remaining 18 patients progressed to severe cases(exacerbated group) during hospitalization. Compared with stable patients, exacerbated patients exhibited older, higher BMI values and higher proportion of smokers. In the exacerbated patients, the median time from onset to deterioration was 7.5 days. Before the time point(days 0–7 from onset), we observed higher-levels of White blood cells(WBC), neutrophil, Neutrophi-Lymphocyte-Ratio(NLR), Lactose-dehydrogenase(LDH), D-dimer, and lower-levels of albumin in the exacerbated group, compared with the stable group. In the second week after the time point, the exacerbated patients displayed lower numbers of lymphocytes, CD3+, and CD8+T-cells, and higher-levels of C-reactive protein(CRP), erythrocyte-sedimentation-rate(ESR), Alanine-aminotransferase(ALT),Aspartate-aminotransferase(AST), and Interleukin-6. In the third week, the highest temperature and the proportion of febrile patients declined. All of the laboratory indicators gradually improved.Conclusions Advanced age and smoking history could be risk factors for COVID-19 progression. In the early stage, high-levels of WBC and neutrophils, with noticeably increased LDH and D-dimer, could be early indicators of the disease’s conversion from mild to severe, followed by elevated inflammatory markers, liver enzymes, and decreased T-lymphocytes in the next week.

2019 novel coronavirus (2019-nCoV) is one of the beta coronaviruses and was identified as the pathogen of the severe "coronavirus disease 2019 (COVID-19)" in 2019. China has formally included the 2019-nCoV in the statutory notification and control system for infectious diseases according to the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases. Currently, the national defending actions on the 2019-nCoV in China is in a critical period. Burn Department is also confronted with risk of infection by the 2019-nCoV. According to the guidelines on the diagnosis and treatment of COVID-19 (6th trial edition), the latest relative literature at home and abroad, the features of the COVID-19, recommendations for the COVID-19 prevention and control issued by the National Health Commission of China, and management experience of diagnosis and treatment in the related disciplines, we put forward recommendations for the medical practices of burn treatment during the outbreak of the COVID-19 in outpatient and emergency treatment, inpatient treatment, operation and ward management, etc. We hope these recommendations could benefit the professionals of the same occupation as us and related hospital managers, improve the treatment of burn during the outbreak of the COVID-19, and avoid or reduce the risk of infection of medical staff .
