Discovering spatiotemporal patterns of COVID-19 pandemic in South Korea.

ABSTRACT: A novel severe acute respiratory syndrome coronavirus 2 emerged in December 2019, and it took only a few months for WHO to declare COVID-19 as a pandemic in March 2020. It is very challenging to discover complex spatial-temporal transmission mechanisms. However, it is crucial to capture essential features of regional-temporal patterns of COVID-19 to implement prompt and effective prevention or mitigation interventions. In this work, we develop a novel framework of compatible window-wise dynamic mode decomposition (CwDMD) for nonlinear infectious disease dynamics. The compatible window is a selected representative subdomain of time series data, in which compatibility between spatial and temporal resolutions is established so that DMD can provide meaningful data analysis. A total of four compatible windows have been selected from COVID-19 time-series data from January 20, 2020, to May 10, 2021, in South Korea. The spatiotemporal patterns of these four windows are then analyzed. Several hot and cold spots were identified, their spatial-temporal relationships, and some hidden regional patterns were discovered. Our analysis reveals that the first wave was contained in the Daegu and Gyeongbuk areas, but it spread rapidly to the whole of South Korea after the second wave. Later on, the spatial distribution is seen to become more homogeneous after the third wave. Our analysis also identifies that some patterns are not related to regional relevance. These findings have then been analyzed and associated with the inter-regional and local characteristics of South Korea. Thus, the present study is expected to provide public health officials helpful insights for future regional-temporal specific mitigation plans.

Hip Fracture Management during the COVID-19 Pandemic in South Korea.

Project description:BackgroundThe purpose of this study was to introduce a screening system for coronavirus disease 2019 (COVID-19), to evaluate the overall orthopedic management in hip fracture patients during the COVID-19 pandemic in South Korea, and to compare the surgical results in hip fracture patients during the COVID-19 pandemic with those of the previous year.MethodsHip fracture patients who visited emergency rooms were screened at the screening clinics before admission. The medical management was carried out with the medical staff wearing surgical masks, meticulous hand hygiene observed, and a minimum distance of 2 m between patients maintained. The demographics, operative parameters, and surgical results of patients treated during the pandemic were compared with those from the previous year.ResultsFrom January 2020 to July 21, 2020, 119 patients with hip fractures (33 men and 86 women) were admitted to our institution for surgical treatment. Five patients showed symptoms of pneumonia, but no patient was positive for COVID-19. The mortality rate during the study period was 4.2%, and none of the patients died due to COVID-19. The interval between admission and surgery and the length of hospital stay were significantly shorter (p = 0.008, p = 0.002) and the proportion of spinal anesthesia was greater in hip fracture patients during the COVID-19 pandemic compared to those from the previous year (p = 0.011).ConclusionsThe COVID-19 screening system for hip fracture patients has proven to be effective in preventing intrahospital spread of the disease. Hip fracture surgery performed during the COVID-19 pandemic has shown comparable results without any COVID-19 infection and COVID-19-related mortality.

COVID-19 in South Korea: epidemiological and spatiotemporal patterns of the spread and the role of aggressive diagnostic tests in the early phase.

Project description:BackgroundSouth Korea experienced the novel coronavirus disease (COVID-19) outbreak in the early period; thus data from this country could provide significant implications for global mitigation strategies. This study reports how COVID-19 has spread in South Korea and examines the effects of rapid widespread diagnostic testing on the spread of the disease in the early epidemic phase.MethodsWe collected daily data on the number of confirmed cases, tests and deaths due to COVID-19 from 20 January to 13 April 2020. We estimated the spread pattern with a logistic growth model, calculated the daily reproduction number (Rt) and examined the fatality pattern of COVID-19.ResultsFrom the start date of the epidemic in Korea (18 February 2020), the time to peak and plateau were 15.2 and 25 days, respectively. The initial Rt was 3.9 [95% credible interval (CI) 3.7 to 4.2] and declined to <1 after 2 weeks. The initial epidemic doubling time was 3.8 days (3.4 to 4.2 days). The aggressive testing in the early days of the epidemic was associated with reduction in transmission speed of COVID-19. In addition, as of 13 April, the case fatality rate of COVID-19 in Korea was 2.1%, suggesting a positive effect of the targeted treatment policy for severe patients and medical resources.ConclusionsOur findings provide important information for establishing and revising action plans based on testing strategies and severe patient care systems, needed to address the unprecedented pandemic.

Deterioration of mental health despite successful control of the COVID-19 pandemic in South Korea.

Project description:South Korea was able to successfully control the spread of COVID-19 without nationwide lockdowns or drastic social distancing efforts, but pandemic-related psychological outcome of the general population remains unknown. Between March and June 2020, 400 South Korean residents participated in an online study of depression, anxiety, stress, psychosis-risk and loneliness, as well as indices of social network, physical health and demographics. Clinical levels of depression, anxiety or stress were reported by 45% of the respondents, and psychosis-risk was present in 12.8%; a drastic increase above the base rate reported by previous studies conducted in South Korea prior to the pandemic. Subjective feelings of loneliness, but not the size of the social network accounted for poor mental health. Women were especially at increased risk for mental health problems. Thus, despite effective mitigation of the pandemic, there was a striking deterioration of mental health. As the psychological burden of the continuing pandemic accrues, the probability of an impending mental health crisis is increasing, especially in countries with greater infection and death rates than South Korea. Comprehensive efforts to address the psychological aftermath of the pandemic are urgently needed.

Changes in energy consumption according to building use type under COVID-19 pandemic in South Korea.

Project description:An unprecedented global lockdown has been implemented for controlling the spread of COVID-19 in many countries. These actions are reducing the number of coronics, but with the prolonged COVID-19 outbreak, the restrictions on the activities of people are having a significant impact on all industries. Accordingly, this study aimed to statistically analyze changes in building energy consumption under the COVID-19 pandemic in South Korea, as well as identify the relationship between COVID-19 and building energy consumption according to the building use type. As a result, the average rate of changes in electricity and gas energy consumption decreased -4.46% and -10.35%, respectively, compared to the previous year. The energy consumption in most facilities has tended to decrease while energy consumption in residential facilities increased during COVID-19. The rate of change in building energy consumption had a significantly positive correlation with COVID-19 related factors in various facilities (e.g., neighborhood, religious, educational, and research facilities). Significant findings of this study that social distancing by the COVID-19 outbreak, has changed energy consumption according to building use type indicates the need for new energy systems to effectively manage the energy demand at the community level in the Post COVID-19 era.

Lifestyle Changes that Impact Personal Quality of Life in the COVID-19 Pandemic in South Korea.

Project description:ObjectiveWe investigated which factors in psychological changes positively or negatively affect the quality of life to suggest desirable directions in the period of the COVID-19 pandemic.MethodsOnline survey was conducted with 1,011 adults more than 19 years old in Busan, South Korea. Quality of life was measured using the World Health Organization Quality of Life-BREF. Questions regarding the psychological changes were about COVID-19-related concerns, distress in complying with quarantine guidelines, and interest in seeking something to do alone.ResultsQuality of life was perceived to be below average (mean±SD, 2.86±0.53). The more economic worries there were, the lower the quality of life in psychological, social relationships and environmental domains. The more distress one experienced when maintaining their personal hygiene, the higher the quality of life related to their physical health. Likewise, the more difficult it was to maintain social distances, the higher the quality of life associated with psychological and social relationships. The more interested someone was in how to spend time alone, the higher the quality of life in all domains significantly.ConclusionWe can minimize the negative impacts of COVID-19 by maintaining economic stability, maintaining prosocial behaviors related to personal hygiene and making good use of personal time.

COVID-19 screening center models in South Korea.

Project description:In a recent report, the British Broadcasting Company (BBC) introduced South Korea's measures to manage COVID-19 as role model for the world. Screening centers serve as frontiers for preventing community transmission of infectious diseases. COVID-19 screening centers in Korea operate 24 h a day, always open for individuals with suspected COVID-19 symptoms. South Korea concentrated COVID-19 screening centers around cities with high population density. Advanced screening centers (models C, D, and E) proved more effective and efficient in the prevention of COVID-19 than the traditional screening centers (models A and B). Particularly, screening centers at Incheon Airport in South Korea prevent transmission through imported cases effectively. It will be important elsewhere, as in South Korea, to establish an infectious disease delivery system that can lead to 'Test-Treat-Track' using an adequate model of screening centers.

The impact of COVID-19 pandemic on orthopaedic resident education: a nationwide survey study in South Korea.

Project description:PURPOSE:There have not been well-designed survey studies investigating the impact of the coronavirus disease 2019 (COVID-19) pandemic on orthopaedic resident education. METHODS:A 58-question, web-based survey was administered to orthopaedic residents in South Korea. A total of 229 orthopaedic residents from 43 hospitals completed the survey questionnaire. RESULTS:The average working time of 72.7 hours/week before the pandemic was decreased to 65.6 hours/week during the pandemic (p?<?0.001). The time working in the operating room was significantly decreased during the pandemic, but not in the emergency centre and outpatient clinic. The education times for lecture and clinical case discussion were decreased during the pandemic (both, p?<?0.001), respectively. While the use of traditional teaching methods was decreased, the use of online-based teaching methods was increased (p?<?0.001). However, satisfaction level with online-based teaching methods was significantly lower compared with that of traditional teaching methods. The average working time exposed to the patients with COVID-19 was 9.7 hours/week. About 47.6% of orthopaedic residents experienced isolation or quarantine. The average score for quality of life, which was 68.9 out of 100 scores before the pandemic, decreased to 61.7 during the pandemic (p?<?0.001). The most stressful factor for orthopaedic residents during the pandemic was family/relative health, followed by their own health and residency program. CONCLUSION:The COVID-19 pandemic had a significant impact on orthopaedic resident education in South Korea. Therefore, flexible and sustainable strategies are necessary to prepare for the future as well as the current pandemic situation.

Current perspective of COVID-19 spread across South Korea: exploratory data analysis and containment of the pandemic.

Project description:The outbreak of severe acute respiratory syndrome coronavirus 2 is regarded as a highly contagious disease that has challenged the healthcare systems worldwide with confirmed cases approaching 12 million and more than 50,000 deaths. Considering the worldwide cases of novel coronavirus disease (COVID-19), it remains a pandemic and the vaccines and therapeutic agents have yet to be developed to stop the spread of this outbreak. Due to the unavailability of specific treatment for the COVID-19, it can be viewed that the risk of cluster infection will continue to be present within the intermittent and small-scale outbreaks. Though the COVID-19 has been identified as a communicable disease, the preventive measures and response policies in South Korea are effectively serving the purpose and gained the confidence to overcome the COVID-19 crisis. This paper includes the exploratory data analysis of COVID-19 cases in South Korea till July 8, 2020. South Korea has reported the lowest death rate with the majority of the deaths, associated with persons with underlying health conditions or elderly infected individuals. Currently the infected patients (total 989) remaining in South Korea are mild cases owing to its robust health care system and quarantine inspection procedures followed by the Ministry of Health and Welfare of South Korea to flatten the COVID-19 curve. Although the COVID-19 countermeasures taken by the South Korean government may not be conclusive or universal for all, but its exemplary approach to tackle COVID-19 can aid countries across the globe to strengthen their response system for the future outbreak of such an infectious disease.
