The spread of an epidemic is a typical public emergency and also one of the major problems that humans need to tackle in the 21st century. Therefore, the research on the spread, prevention, and control of epidemics is quite an essential task. This paper first briefly described and analyzed the development of COVID-19 and then introduced the basic epidemic models and idealized the population in the epidemic area by dividing them into four categories (Classes S, E, I, and R). After that, it set the relevant parameters of the basic SEIR model and the modified one and worked out the relevant differential equations and iterative equations. According to the feature of the epidemic situation and the changes in the number of contacts in different units of time, the epidemic data were substituted into the iterative equations for data fitting with an R Package. Then, analysis was performed on the epidemiological features such as the transmission time and epidemic peak and the epidemic trend was evaluated. Finally, sensitivity analysis was conducted on the parameters (government control and recovery rate), and the results showed that measures such as government restrictions on travel (reducing the contacts between virus carriers and susceptible persons) can effectively control the scale of the outbreak.

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.

New coronavirus pneumonia has had a significant impact on people's health and safety since the outbreak in the early 2020. The latest version of the new coronavirus pneumonia virus is still spreading around the world. China's public health system has passed a severe test: under the leadership of the Chinese Communist Party and the joint efforts of people of all ethnic groups, China won a great victory in the anti-epidemic campaign. Nevertheless, the public health system has also identified some challenges that need to be actively addressed in the area of medicine and health during the prevention and control of epidemics. This article deals with these issues.

BACKGROUND Sufficient emergency preparedness is the key factor to respond effectively and recover from major emergent infectious diseases (MEID). However, in the face of MEID, public emergency preparedness is insufficient, so it is urgent to improve public emergency preparedness. The rapid development of virtual reality and human-computer interaction provides unprecedented opportunities for innovative education methods. OBJECTIVE To design a virtual reality interactive training system (VRITS) to improve public emergency preparedness under MEID, so that the public can respond effectively and recover from MEID. METHODS This study takes the interactive narrative theory, situated learning theory and human-computer interaction theory as the theoretical framework to guide the design of software. Using literature research method and Delphi method, consulting and interviewing multi-disciplinary experts such as pedagogy, medicine, psychology, public health and computer to determine the educational content framework and operating system framework of the VRITS. RESULTS The VRITS is named the People’s War Against Epidemic. The educational content framework includes 21 knowledge, emotion and behavior skills in six aspects, such as cooperating with prevention and control work, improving basic equipment, ensuring personal safety, preparing economic resources, managing self-emotion, and improving emergency response ability. The operating system framework includes virtual interactive training module, knowledge corner module, intelligent evaluation module and community forum module, and the core module is a virtual interactive training module. In this module, users control the virtual characters to move in various scenes in the community, and then identify and analyze the controllability and harmfulness of the evolving epidemic and selects the correct prevention and control strategy to avoid infection by themselves and others. CONCLUSIONS The People’s War Against Epidemic creates a realistic learning situation for the trainers, enhances the immersion and experience of the trainers, enriches the theoretical system and education resource database of emergency preparedness training under the MEID, and improves the effectiveness, fairness, accessibility and participation of education.

Key Words Infections

Infection with IPHC occurs in medical institutions together with the underlying disease, complicates its clinical course, complicates the diagnosis and treatment of the disease, complicates the prognosis and outcome of the disease, and sometimes leads to the death of the patient. The main task of the hospital staff is to completely and quickly restore the health of hospitalized patients and create safe and comfortable conditions for them there. To do this, it is necessary to study the epidemiological characteristics of IPHC and implement their prevention and control. Key words: infections associated with the provision of medical care, nosocomial infections, epidemiological features, risk factors
