The COVID-19 outbreak is a manifestation of the contradiction between man and land. Geography plays an important role in epidemic prevention and control with its cross-sectional characteristics and spatial perspective. Based on a systematic review of previous studies, this paper summarizes the research progress on factors influencing the spatial spread of COVID-19 from the research content and method and proposes the main development direction of geography in epidemic prevention and control research in the future. Overall, current studies have explored the factors influencing the epidemic spread on different scales, including global, national, regional and urban. Research methods are mainly composed of quantitative analysis. In addition to the traditional regression analysis and correlation analysis, the spatial lag model, the spatial error model, the geographically weighted regression model and the geographic detector have been widely used. The impact of natural environment and economic and social factors on the epidemic spread is mainly reflected in temperature, humidity, wind speed, air pollutants, population movement, economic development level and medical and health facilities. In the future, new technologies, new methods and new means should be used to reveal the driving mechanism of the epidemic spread in a specific geographical space, which is refined, multi-scale and systematic, with emphasis on exploring the factors influencing the epidemic spread from the perspective of spatial and behavioral interaction, and establish a spatial database platform that combines the information of residents’ cases, the natural environment and economic society. This is of great significance to further play the role of geography in epidemic prevention and control.

SummaryBackgroundThe 2019 new coronavirus, “2019-nCoV”, was discovered from Wuhan Viral Pneumonia cases in December 2019, and was named by the World Health Organization on January 12, 2020. In the early stage, people knows little about the 2019-nCoV virus was not clear, and the spread period was encountering China’s annual spring migration, which made the epidemic spread rapidly from Wuhan to almost all provinces in China.MethodsThis study builds a SEIRD model that considers the movement of people across regions, revealing the effects of three measures on controlling the spread of the epidemic.Based on MATLAB R2017a, computational experiments were performed to simulate the epidemic prevention and control measures.FindingsThe research results show that current prevention and control measures in China are very necessary. This study further validates the concerns of international and domestic experts regarding asymptomatic transmission (E-status).InterpretationThe results of this study are applicable to explore the impact of the implementation of relevant measures on the prevention and control of epidemic spread, and to identify key individuals that may exist during the spread of the epidemic.

People with multiple sclerosis (PwMS) often experience uncertainty and fear about their futures. Partners of PwMS may share their concerns and experience fears about their own futures, limitations on their lives, ability to work, and becoming a carer. For PwMS, modification of lifestyle-related risk factors has been associated with improved health outcomes. For PwMS who attended residential lifestyle modification workshops (RLMW), sustained improved health outcomes have been demonstrated. Whether improved outcomes for PwMS who engage with lifestyle modification translate to improved partner perceptions of the future, is yet to be explored. We explored the perspectives of partners of PwMS who had attended a RLMW and the impact that the person with MS’s illness and their engagement with lifestyle modification had on their partners’ views of the future. Analysis of 21 semi-structured interviews used a methodology informed by Heidegger’s Interpretive Phenomenology. Three themes emerged: ‘uncertainty’, ‘planning for the future’ and ‘control, empowerment and confidence’. Subthemes included MS and lifestyle modification being a catalyst for positive change; developing a sense of control and empowerment; and hope, optimism and positivity. Lifestyle modification may provide benefits, not only to PwMS, but also to their partners, and should be considered part of mainstream management of MS.

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.

Objectives: Through the reflection on the city’s response to the crisis in the process of tobacco control, a comprehensive and systematic public safety prevention and control system will be built to help cities cope with future risks and challenges. Methods: By using the methodological principle of the unity of subject and object and systematic research, this paper analyzes the problems from the three aspects of subject, object and means, and puts forward three important links of prevention, response and guarantee to construct a large urban public security system, and these three links support each other form a closed loop of risk prevention and control urban public security. Results: Under the background of tobacco control, it is feasible to a reliable whole-cycle management system for urban emergency response and accident rescue, a sound basic public safety guarantee system and a whole-society participation system. Conclusions: Due to the change of global climate conditions and the increase of flow people in the social environment, human beings will face a more complex living environment in the future and may encounter more extreme problems. It can be said that at present and even in the future, global urban public security risk management work is facing a grim situation. WHO research shows that smoking will increase the risk of new crown virus infection among smokers and their surrounding population.China is a big smoking country and in the stage of rapid urbanization. Many citiesare densely populated. Once there is an epidemic infection, the cities will face a severe public security situation. Smoking will not only have an adverse impact on personal health, but also the fires in factories, homes and forests caused by smoking.Since the Chinese government’s tobacco control in 2014, various accidents caused by smoking have caused great adverse effects.Smoking in public places has great hidden dangers of public safety, which leads us to think about the risk management of urban public safety.In the context of tobacco control, we should use scientific thinking and methods to construct a new pattern of urban public security risk management. Another important concept is to implement the risk management concept and the value of prevention first in the management of public affairs, so as to create a situation of risk sharing and coordinated response of the whole society.
