High-Resolution CT Features of the COVID-19 Infection During Short-Term Follow-Up

Objective: To estimate the short-term follow-up chest HRCT manifestation in patients with COVID-19 who have left hospitals. Methods: Retrospective analysis was executed on the chest HRCT manifestation of 49 cases with RT-PCR confirmed COVID-19 pneumonia patients diagnosed in Beijing You’An hospital affiliated to capital medical university between 20 January 2020 to April 10, 2020. The study including 21 males and 28 females, and the median age was 59.5 years age ranged from 21 years to 80 years. The evolution characteristics of chest HRCT in short-term follow-up after discharge were analyzed. Results: Forty-nine patients were divided into two groups according to Diagnosis and Treatment Protocol of 2019 New Coronavirus Pneumonia (trial version 7) of National Health Commission of China. Severe group included 23 cases (46.9%) and 26 cases of ordinary (53.1%). The HRCT findings of patients in the 2 groups were analyzed on median follow-up time was 30 day (range, 14 to 46 days) after discharge. The follow-up chest HRCT were normal in 19 of 49 (38.8%) patients, abnormal HRCT findings were detected in 30 of 49 (61.2%) patients. The most frequent abnormality found on follow-up HRCT in COVID-19 patients who recovered from pneumonia was GGO which was seen in 26 of 49 (53.1%) patients, reticular pattern was in 9 of 49 (18.4%), traction bronchiectasis was in 3 of 49 (6.1%), small nodular consolidation was in 6 of 49 (12.2%), other findings including curved line in the subpleural area and irregular linear opacities were in 15 of 49 (30.6%). In the study, 3 of 49 (6.1%) patients were diagnosed with pulmonary fibrosis according to HRCT findings. Three cases were severe patients, aged from 65 to 80 years. Pulmonary fibrosis occurred within 30–50 days of onset. Conclusion: Pulmonary fibrosis may develop in 6.1% of COVID-19 patients, which was lower than that of SARS and MERS, suggesting that the lung damage caused by SARS-COV-2 in the recovered patients was lower than that of SARS and MERS.

An Analysis of the Work Resumption in China under the COVID-19 Epidemic Based on Night Time Lights Data

Public emergencies often have an impact on the production and operation of enterprises. Timely and effective quantitative measurement of enterprises’ offline resumption of work after public emergencies is conducive to the formulation and implementation of relevant policies. In this study, we analyze the level of work resumption after the coronavirus disease 2019 (COVID-19)-influenced Chinese Spring Festival in 2020 with night time lights remote sensing data and Baidu Migration data. The results are verified by official statistics and facts, which demonstrates that COVID-19 has seriously affected the resumption of work after the Spring Festival holiday. Since 10 February, work has been resuming in localities. By the end of March, the work resumption index of most cities exceeded 70% and even Shanghai, Nanjing and Suzhou had achieved complete resumption of work. Wuhan only started to resume work in the last week of March due to the more severe outbreak. Although the level of work resumption is gradually increasing in every area, the specific situation of resumption of work varies in different regions. The process of work resumption in coastal areas is faster, while the process is relatively slow in inland cities.

Characteristics of Misinformation Spreading on Social Media During the COVID-19 Outbreak in China: A Descriptive Analysis.

BACKGROUND: During a public health emergency, social media is a major conduit or vector for spreading health misinformation. Understanding the characteristics of health misinformation can be a premise for rebuking and purposefully correcting such misinformation on social media. METHODS: Using samples of China's misinformation on social media related to the COVID-19 outbreak (N=547), the objective of this article was to illustrate the characteristics of said misinformation on social media in China by descriptive analysis, including the typology, the most-mentioned information, and a developmental timeline. RESULTS: The results reveal that misinformation related to preventive and therapeutic methods is the most-mentioned type. Other types of misinformation associated with people's daily lives are also widespread. Moreover, cultural and social beliefs have an impact on the perception and propaganda of misinformation, and changes in the crisis situation are relevant to the type variance of misinformation. CONCLUSION: Following research results, strategies of health communication for managing misinformation on social media are given, such as credible sources and expert sources. Also, traditional beliefs or perceptions play the vital role in health communication. To sum up, combating misinformation on social media is likely not a single effort to correct misinformation or to prevent its spread. Instead, scholars, journalists, educators, and citizens must collaboratively identify and correct any misinformation.

Evidence-based decision-making for a public health emergency in China: Easier said than done

This article aims to argue that evidence-based decision-making for a public health emergency is "easier said than done" reflected on COVID-19 response in China. For the local government, the behavioral pattern is prone to blame-avoiding instead of making decision following scientific evidence and experts' advice. However, such behavior is not based on completely subjective judgment but a rational choice for the local government. Some consequences associated with China's response to COVID-19 reveals an inflexible administrative system. Therefore, China's governance reform should focus on empowering local governments with more flexibility and resilience, which enables local governments to make independent and scientific decisions in an emergency.

Community Disaster Resilience in the COVID-19 Outbreak: Insights from Shanghai's Experience in China.

PURPOSE: Communities are central to the practice of public health emergency preparedness and response. This article mainly focuses on COVID-19 and discusses the formation and structure of community disaster resilience, which is an effective method for coping with such a public health emergency. METHODS: Based on the management of the COVID-19 outbreak in China, this article uses Shanghai's experience to illustrate how a community disaster resilience was formed for risk management. Resorting to the analytical framework of risk city, principles of community disaster resilience are given. RESULTS: Four actions can be recommended based on Shanghai's experience: 1) Applying a vulnerability analysis matrix for targeted risk governance, 2) empowering volunteer groups for emergency response, 3) policy and action for public health emergency prevention, and 4) risk communication for uncertainty-oriented planning. CONCLUSION: Shanghai's experience offers a reference to tackle the COVID-19 at the global level. The COVID-19 outbreak highlights that humans still face various unpredictable health risks in the future. Forming a connection-based resilience at the community level is an effective way to risk management.

How the Health Rumor Misleads People's Perception in a Public Health Emergency: Lessons from a Purchase Craze during the COVID-19 Outbreak in China.

Health rumors often mislead people and cause adverse health behaviors. Especially during a public health emergency, health rumors may result in severe consequences for people's health and risk governance. Insight into how these rumors form and harm people's health behavior is critical for assisting people in establishing scientific health cognition and to enhance public health emergency responses. Using the case study with interview data of a salient purchase craze led by a health rumor during the COVID-19 outbreak in China, this article aimed to illustrate the process of how a piece of information becomes a health rumor. Furthermore, we identify factors that cause people to believe rumors and conduct behavior that leads to a purchase craze. Results show that a public misunderstanding of the unique psychology of uncertainty, cultural and social cognition, and conformity behavior jointly informs people's beliefs in rumors and further causes purchase craze behavior. We developed a simplified model to demonstrate how an ordinary news report can lead to a rumor. Based on this model, some implications of effective health communication are suggested for managing rumors.
