Objective To establish an index system for comprehensive evaluation of public health risks of the coronavirus diseases 2019(COVID-19),and to evaluate the COVID-19 in different counties(districts) of Wenzhou, so as to provide scientific evidence for the implementation of targeted prevention and control measures. Methods Rank-sum ratio(RSR) was used to evaluate 12 quality indicators of 5 categories by brain storming method with data including the incidence of COVID-19 and public health risks of COVID-19 epidemic in Wenzhou during January and February, 2020.The regional public health risks of COVID-19 were ranked according to rank-sum ratio size. Results The top three counties(districts) with most reported cases were Yueqing,Rui′an and Lucheng,accounting for 61.90%(312/504) of the total number in Wenzhou.The ratio of import cases to indigenous cases was 1∶1.39.The top three counties(districts) reported most clustering epidemics were Yueqing,Rui′an and Lucheng,accounting for 62.03%(49/79) of the total number in Wenzhou.About 70.63%(356/504)of the cases were found before the medical visit.The time from onset to first medical visit was 2.39 d, and the time from medical visit to diagnosis was 4.49 d.The average number of close contacts for confirmed cases was 29,and the top three counties(districts)with most reported average number of close contacts were Jingkai(135 cases),Dongtou(59 cases)and Cangnan(50 cases).Among all13 counties(districts),Longgang,Wencheng and Jingkai were at lower level,Yueqing and Lucheng were at higher level,and the other counties(districts)were at the middle level of public health risks of COVID-19. Conclusions RSR method is flexible and simple.It has no specific requirements on samples,and can eliminate the effects of comprehensive assessment indexes of different dimension.It has high value in evaluating public health risks of the COVID-19.The evaluating of public health risks of COVID-19 should be strengthened.Targeted prevention and control measures should be taken to positively prevent the outbreak of COVID-19.

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.
