RESUMEN
In November 2021, 14 international travel-related severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.529 (omicron) variant of concern (VOC) patients were detected in South Korea. Epidemiologic investigation revealed community transmission of the omicron VOC. A total of 80 SARS-CoV-2 omicron VOC-positive patients were identified until December 10, 2021 and 66 of them reported no relation to the international travel.There may be more transmissions with this VOC in Korea than reported.
RESUMEN
Background@#Following the coronavirus disease 2019 (COVID-19) outbreak in Wuhan, China, a total of 637 patients had been diagnosed with the disease in Seoul as of May 2, 2020. Our study aimed to describe the impact of the 3T strategies (preemptive testing, prompt tracing and proper treatment) on the epidemiological characteristics of COVID-19 in Seoul. @*Methods@#The descriptive and explanatory analysis was carried out on critical indicators such as epidemiological characteristics and key duration of patient status change from January 24 to May 2 in Seoul before and after preemptive testing for patients under investigation associated with COVID-19 clusters. @*Results@#Preemptive testing increased the positive test rate (3.9% to 4.2%), an asymptomatic case at diagnosis (16.9% to 30.6%), and reduced the time from symptom onset to quarantine (4.0 to 3.0 days). Prompt tracing decreased unknown sources of infection (6.9% to 2.8%), the mean number of contacts (32.2 to 23.6), and the time-varying reproduction number R(t) (1.3 to 0.6). With proper treatment, only 2 cases of mortality occurred, resulting in a fatality rate of just 0.3%. @*Conclusion@#In the first wave of the COVID-19 pandemic lasting 100 days, the effect of the 3T strategies flattened the curve and decreased the time during which infected individuals were contagious, thereby lowering the R(t) below 1 in Seoul.
RESUMEN
OBJECTIVES: This study aimed to examine the association between public social expenditure (PSE) and suicides in the 27 countries of the Organization for Economic Cooperation and Development (OECD) from 1980 to 2003. METHODS: The age-standardized suicide rates and their annual change (%) were obtained from the OECD Health Data 2007. As a measure of social protection, the PSE (% GDP) was used. The covariates included the annual divorce rate (/100,000 population), fertility rate (number of children/woman aged 15 to 49 years), GDP per capita (US$PPP), male unemployment rate (%), life expectancy (years) and alcohol consumption (liter/capita) for each country, which were all obtained from the OECD Health Data 2007 and the OECD Social Indicators 2006. Using hierarchical linear models that included these covariates, the effects of PSE on suicides (Model 1) and the annual percent change (Model 2) were examined (Model 3). Also, sub-sample analyses were done for six countries that experienced political/economic transition. RESULTS: We could not find significant effects of PSE on suicides (Model 1), but we observed significantly negative effects on the annual percent change for men and women (Model 2). Such findings were replicated in the sub-sample analysis, and moreover, the effect size was much larger (Model 3). CONCLUSIONS: Our finding suggests that social welfare protection can be a pivotal factor for suicide epidemiology, and especially in countries experiencing a social crisis or transition.
