At the beginning of 2020, COVID-19 broke out. After the COVID-19 outbreak, online media became an important channel for the masses to obtain information about the epidemic. According to the different social functions of various online media, this paper classifies the important online media in this epidemic into four categories, namely, official media, government media, market-oriented media and We-media. By using the crawler software tool, crawling the Weibo data of the People’s Daily, The Paper, Healthy China, and Doctor Do of Concord, from January 1, 2020, to March 1, 2020, combined with the data of confirmed cases of the domestic novel coronavirus epidemic in the same period, constructed a multiple regression model to conduct empirical research on the effects of online media on different subjects. The research results show that official new media and market-based media are negatively correlated with the number of people infected with the epidemic, whereas government media are more inclined to reflect the law of the development of the epidemic and are positively correlated with the development of the epidemic. Therefore, taking the initiative to grasp the public opinion guidance of the official media and market-oriented media can achieve better publicity effect in the epidemic prevention and control work.

AbstractBackgroundSince late December 2019, a novel coronavirus (COVID-19) has emerged in Wuhan and rapidly spread throughout China. Fears were raised higher, effective policies for prevention and control were concerned.MethodsTill March 3, 91273 confirmed COVID-19 cases were included in. Using Mann-Whitney U test, the provinces that reported the life tracks of confirmed cases to public had lower increased in daily new confirmed cases.ResultsCompared with the paired province, Tianjin, Jilin, Gansu, Shanxi, Hainan and Guizhou had significant differences in the number of new confirmed cases and have lower mean rank (P<0.05). Shanghai had a lower mean rank (P=0.175) but no significant difference. Besides, the successful prevention and control work need other effective strategies, such as real time media coverage, isolating the suspected cases or close contacts, delaying the return of work, closing schools, wearing facial masks, and disinfecting the communities, et.al.ConclusionsStrategies must be adjusted in real time according to the epidemic. Reporting the life tracks of confirmed cases was an effective way to control the epidemic. They may be suggestions to other counties with an outbreak of COVID-19.

<p align="justify">At the end of 2017, Chinese student Jiang Ge was murdered in Japan. With the help of the online we-media Mi Meng and others, there is widespread attention in China. The moral condemnation by online we-media of Liu Xin, another victim of the case, and online violence has become another case that the media makes the judge before the judiciary. Trial by media is not a new subject, and in the cyber age, especially with the increasingly prosperous development of online media, the “trial by media” power cannot be underestimated. This article, taking the “Death of Jiang Ge” as a perspective, briefly analyzes the causes and characteristics of the trial by online we-media in the Internet age, and puts forward some thoughts on the prevention and control strategies of the “trial by media” in the future.</p>

Start your abstract here…In late 2019, a new coronavirus, SARS-CoV-2 outbreak began in China and has since spread around the world, causing nearly one million deaths. By the time this article was written, most countries were still in high-and medium-risk, and this pandemic may continue to the year 2021 or even later. However, when this virus first appeared is still under debate. In this paper, I employ a realistic model and the officially reported data to investigate when SARS-CoV-2 first appeared in China, and how many people were infected with the novel coronavirus at the beginning of Dec in 2019. In addition, I used simulation to get the relationship between imported cases and local intervention measures to predict the current intervention level in China. Based on the first part of the simulation, the result indicate that the number and time of the initial cases reported in China might have under a certain inaccuracy. This underestimation of the severity of the pandemic delayed the progress of epidemic prevention and control. In addition, the increase or decrease of imported cases and the intensity of epidemic prevention measures will directly affect the arrival of the epidemic peak. Of course, the number of incoming cases at this time also has a direct impact on the number of deaths and confirmed patients. We used the model to simulate the overall diagnosis of the disease in Wuhan in the early and late stages of the epidemic, and to approximate the difference between the real and the official data. In addition, we also for the late number of imported cases and different intervention has been analyzed, for the future of the normalization of prevention and control recommendations.

In a large-scale epidemic, such as the novel coronavirus pneumonia (COVID-19), there is huge demand for a variety of medical supplies, such as medical masks, ventilators, and sickbeds. Resources from civilian medical services are often not sufficient for fully satisfying all of these demands. Resources from military medical services, which are normally reserved for military use, can be an effective supplement to these demands. In this paper, we formulate a problem of integrated civilian-military scheduling of medical supplies for epidemic prevention and control, the aim of which is to simultaneously maximize the overall satisfaction rate of the medical supplies and minimize the total scheduling cost, while keeping a minimum ratio of medical supplies reservation for military use. We propose a multi-objective water wave optimization (WWO) algorithm in order to efficiently solve this problem. Computational results on a set of problem instances constructed based on real COVID-19 data demonstrate the effectiveness of the proposed method.

Abstract Background Based on differences in populations and prevention and control measures, the spread of new coronary pneumonia in different countries and regions also differs. This study aimed to calculate the transmissibility of coronavirus disease 2019 (COVID-19), and to evaluate the effectiveness of measures to control the disease in Jilin Province, China. Methods The data of reported COVID-19 cases were collected, including imported and local cases from Jilin Province as of March 14, 2019. A Susceptible–Exposed–Infectious–Asymptomatic–Recovered/Removed (SEIAR) model was developed to fit the data, and the effective reproduction number (Reff) was calculated at different stages in the province. Finally, the effectiveness of the measures was assessed. Results A total of 97 COVID-19 infections were reported in Jilin Province, among which 45 were imported infections (including one asymptomatic infection) and 52 were local infections (including three asymptomatic infections). The model fit the reported data well (R2 = 0.593, P < 0.001). The Reff of COVID-19 before and after February 1, 2020 was 1.64 and 0.05, respectively. Without the intervention taken on February 1, 2020, the predicted cases would have reached a peak of 177,011 on October 22, 2020 (284 days from the first case). The projected number of cases until the end of the outbreak (on October 9, 2021) would have been 17,129,367, with a total attack rate of 63.66%. Based on the comparison between the predicted incidence of the model and the actual incidence, the comprehensive intervention measures implemented in Jilin Province on February 1 reduced the incidence of cases by 99.99%. Therefore, according to the current measures and implementation efforts, Jilin Province can achieve good control of the virus’s spread. Conclusions COVID-19 has a moderate transmissibility in Jilin Province, China. The interventions implemented in the province had proven effective; increasing social distancing and a rapid response by the prevention and control system will help control the spread of the disease.

The Impact

The COVID-19 pandemic is a major challenge for society as a whole, and analyzing the impact of the spread of the epidemic and government control measures on the travel patterns of urban residents can provide powerful help for city managers to designate top-level epidemic prevention policies and specific epidemic prevention measures. This study investigates whether it is more appropriate to use groups of POIs with similar pedestrian flow patterns as the unit of study rather than functional categories of POIs. In this study, we analyzed the hour-by-hour pedestrian flow data of key locations in Beijing before, during, and after the strict epidemic prevention and control period, and we found that the pedestrian flow patterns differed greatly in different periods by using a composite clustering index; we interpreted the clustering results from two perspectives: groups of pedestrian flow patterns and functional categories. The results show that depending on the specific stage of epidemic prevention and control, the number of unique pedestrian flow patterns decreased from four before the epidemic to two during the strict control stage and then increased to six during the initial resumption of work. The restrictions on movement are correlated with most of the visitations, and the release of restrictions led to an increase in the variety of unique pedestrian flow patterns compared to that in the pre-restriction period, even though the overall number of visitations decreased, indicating that social restrictions led to differences in the flow patterns of POIs and increased social distance.

ABSTRACTBackgroundWorking under pandemic conditions exposes health care workers (HCWs) to infection risk and psychological strain. Protecting the physical and psychological health of HCWs is a key priority. This study assessed the perceptions of European hospital HCWs of local infection prevention and control (IPC) procedures during the COVID-19 pandemic and the impact on their emotional wellbeing.MethodsWe performed two rounds of an international cross-sectional survey, between 31 March and 17 April 2020 via existing research networks (round 1), and between 14 May and 31 August 2020 via online convenience sampling (round 2). Main outcome measures were (1) behavioural determinants of HCW adherence with IPC procedures, (2) WHO-5 Well-Being Index, a validated scale of 0-100 reflecting emotional wellbeing. The WHO-5 was interpreted as a score below or above 50 points, a cut-off score used in previous literature to screen for depression.Results2,289 HCWs (round 1: n=190, round 2: n=2,099) from 40 countries in Europe participated. Mean age of respondents was 42 (±11) years, 66% were female, 47% and 39% were medical doctors and nurses, respectively. 74% (n=1699) of HCWs were directly treating patients with COVID-19, of which 32% (n=527) reported they were fearful of caring for these patients. HCWs reported high levels of concern about COVID-19 infection risk to themselves (71%) and their family (82%) as a result of their job. 40% of HCWs considered that getting infected with COVID-19 was not within their control. This was more common among junior than senior HCWs (46% versus 38%, P value <.01). Sufficient COVID-19-specific IPC training, confidence in PPE use and institutional trust were positively associated with the feeling that becoming infected with COVID-19 was within their control. Female HCWs were more likely than males to report a WHO-5 score below 50 points (aOR 1.5 (95% confidence interval (CI) 1.2-1.8).ConclusionsIn Europe, the COVID-19 pandemic has had a differential impact on those providing direct COVID-19 patient care, junior staff and women. Health facilities must be aware of these differential impacts, build trust and provide tailored support for this vital workforce during the current COVID-19 pandemic.

Severe acute respiratory syndrome coronavirus – 2 (SARS-CoV-2), an emerging novel coronavirus causing coronavirus disease 2019 (COVID-19) pandemic, has now rapidly spread to more than 215 countries and has killed nearly 0.75 million people out of more than 20 million confirmed cases as of 10th August, 2020. Apart from affecting respiratory system, the virus has shown multiple manifestations with neurological affections and damaging kidneys. SARS-CoV-2 transmission mainly occurs through close contact of COVID-19 affected person, however air-borne route is also now considered as dominant route of virus spread. The virus has been implicated to have originated from animals. Apart from bats, pangolins and others being investigates to play role in transmitting SARS-CoV-2 as intermediate hosts, the recent reports of this virus infection in other animals (cats, dogs, tigers, lions, mink) suggest one health approach implementation along with adopting appropriate mitigation strategies. Researchers are pacing to develop effective vaccines and drugs, few reached to clinical trials also, however these may take time to reach the mass population, and so till then adopting appropriate prevention and control is the best option to avoid SARS-CoV-2 infection. This article presents an overview on this pandemic virus and the disease it causes, with few recent concepts and advances.
