COVID-19 is a highly infectious disease and public health hazard that has been wreaking havoc around the world; thus, assessing and simulating the risk of the current pandemic is crucial to its management and prevention. The severe situation of COVID-19 around the world cannot be ignored, and there are signs of a second outbreak; therefore, the accurate assessment and prediction of COVID-19 risks, as well as the prevention and control of COVID-19, will remain the top priority of major public health agencies for the foreseeable future. In this study, the risk of the epidemic in Guangzhou was first assessed through logistic regression (LR) on the basis of Tencent-migration data and urban point of interest (POI) data, and then the regional distribution of high- and low-risk epidemic outbreaks in Guangzhou in February 2021 was predicted. The main factors affecting the distribution of the epidemic were also analyzed by using geographical detectors. The results show that the number of cases mainly exhibited a declining and then increasing trend in 2020, and the high-risk areas were concentrated in areas with resident populations and floating populations. In addition, in February 2021, the “Spring Festival travel rush” in China was predicted to be the peak period of population movement. The epidemic risk value was also predicted to reach its highest level at external transportation stations, such as Baiyun Airport and Guangzhou South Railway Station. The accuracy verification showed that the prediction accuracy exceeded 99%. Finally, the interaction between the resident population and floating population could explain the risk of COVID-19 to the highest degree, which indicates that the effective control of population agglomeration and interaction is conducive to the prevention and control of COVID-19. This study identifies and predicts high-risk areas of the epidemic, which has important practical value for urban public health prevention and control and containment of the second outbreak of COVID-19.

As the most infectious disease in 2020, COVID-19 is an enormous shock to urban public health security and to urban sustainable development. Although the epidemic in China has been brought into control at present, the prevention and control of it is still the top priority of maintaining public health security. Therefore, the accurate assessment of epidemic risk is of great importance to the prevention and control even to overcoming of COVID-19. Using the fused data obtained from fusing multi-source big data such as POI (Point of Interest) data and Tencent-Yichuxing data, this study assesses and analyzes the epidemic risk and main factors that affect the distribution of COVID-19 on the basis of combining with logistic regression model and geodetector model. What’s more, the following main conclusions are obtained: the high-risk areas of the epidemic are mainly concentrated in the areas with relatively dense permanent population and floating population, which means that the permanent population and floating population are the main factors affecting the risk level of the epidemic. In other words, the reasonable control of population density is greatly conducive to reducing the risk level of the epidemic. Therefore, the control of regional population density remains the key to epidemic prevention and control, and home isolation is also the best means of prevention and control. The precise assessment and analysis of the epidemic conducts by this study is of great significance to maintain urban public health security and achieve the sustainable urban development.

BACKGROUND: The novel Coronavirus Diseases 2019 (COVID-19) is the major public health burden in the world. The morbidity and mortality of global community due to this disease is dramatically increasing from time to time. OBJECTIVE: This situational analysis is aimed to analysis prevalence, and incidence of COVID-19 and to provide clear information about this disease for the scientific community, stakeholders and healthcare practitioners and decision-makers. METHODS: The literatures were identified by searching the key relevant and officially known online databases: medRxiv, Google scholar and PubMed. The online databases contain archives of most English biomedical journals and scientific papers published online from 31 December to 3 April 2020 were included. After the literature search, articles were screened independently by two reviewers for eligibility. RESULTS: The world continents have confirmed a total of 1,202,320 confirmed COVID-19 cases: (51.2%) in Europe, (27.7%) in North America, (17.9%) in Asia, (1.96%) in South America and at less number of confirmed COVID-19 cases in Africa and Australia which was accounted 0.8% and 0.5%, respectively. However, this review showed that there was significantly increased the confirmed COVID-19 cases by 109,555 in Asia, 8,658 in Africa, 332,866 in North America, 20,269 in South America, 568,894 in Europe, 5,051 in Australia and 1,045,403 in the whole world continent except Antarctica during the review period. The overall results showed that there were 1,098,762 cases and 59,172 deaths have recorded from during the review period. The result zero number of deaths with COVID-19 was observed in 66 countries. CONCLUSION: The review concluded that COVID-19; SARS-CoV-2 is the major public health burden in the world, the morbidity and mortality of global community is dramatically increasing from time to time. Strongly collaboration among all sectors and then design effective prevention and control strategies which include staying home, social/physical distancing, quarantine, testing of suspected patients, isolation and managing of the confirmed cases. Therefore, the world continents countries should have to implement five major COVID-19 prevention and control programmes as soon as possible at community level.

With the frequent occurrence of epidemic diseases such as “SARS”, “H1N1”, “MERS”and“COVID19”, public health emergencies, which are characterized by large-scale, high risk, strong persistence and high risk, have become more and more obvious threats to the life and health of urban residents and put forward a huge test to the urban public service system. As the first city of COVID-19 human infection, the core of the epidemic spread and the worst-hit area, Wuhan is an ideal case study. Based on the analysis of the epidemic prevention and control actions in the first three months of the outbreak in Wuhan, this paper evaluates the vulnerability of the public service system and facilities in Wuhan. The results show that Wuhan is faced with many problems, such as the failure of community-level public service facilities, the imbalance of public service allocation in the central city, and the significant gap of graded service supply, when dealing with public health emergencies. Further studies found that due to the lack of dynamic early warning mechanism, the decoupling of public service construction from the urbanization process, the difficulty of service turnover and subsidence and other factors, the public service response was delayed. Based on these practical difficulties, this paper puts forward the construction path of the emergency response mechanism for the city level public service system, specifically including the following six key contents: (1) Improving the emergency plan path of the public service system; (2) Establishing the organizational structure of the emergency management system according to the administrative divisions; (3) Building a community-based mobilization system; (4) Establishing the regional joint defense and control interaction mechanism in public health emergencies; (5) Reserving appropriate strategic construction space; (6) Strengthening the emergency infrastructure construction. Finally, based on the path of emergency response mechanism, this paper proposes the corresponding city wide spatio-temporal prevention and control network strategy, so as to provide a reference for the realization of city health and order.

Background China’s “13th 5-Year Plan” (2016–2020) for the prevention and control of sudden acute infectious diseases emphasizes that epidemic monitoring and epidemic focus surveys in key areas are crucial for strengthening national epidemic prevention and building control capacity. Establishing an epidemic hot spot areas and prediction model is an effective means of accurate epidemic monitoring and surveying. Objective: This study predicted hemorrhagic fever with renal syndrome (HFRS) epidemic hot spot areas, based on multi-source environmental variable factors. We calculated the contribution weight of each environmental factor to the morbidity risk, obtained the spatial probability distribution of HFRS risk areas within the study region, and detected and extracted epidemic hot spots, to guide accurate epidemic monitoring as well as prevention and control. Methods: We collected spatial HFRS data, as well as data on various types of natural and human social activity environments in Hunan Province from 2010 to 2014. Using the information quantity method and logistic regression modeling, we constructed a risk-area-prediction model reflecting the epidemic intensity and spatial distribution of HFRS. Results: The areas under the receiver operating characteristic curve of training samples and test samples were 0.840 and 0.816. From 2015 to 2019, HRFS case site verification showed that more than 82% of the cases occurred in high-risk areas. Discussion This research method could accurately predict HFRS hot spot areas and provided an evaluation model for Hunan Province. Therefore, this method could accurately detect HFRS epidemic high-risk areas, and effectively guide epidemic monitoring and surveyance.
