  On December 1, 2021, SARS-CoV-2 B.1.1.529 (Omicron) variant of concern (VOC) was identified for the first time in the Republic of Korea (ROK) and a total of 123 cases with Omicron VOC were identified through quarantine and community epidemiological surveys. As of December 12, 2021, among them, a total number of cases (123), 90 cases were confirmed through RT-PCR and NGS analysis and 33 epidemiological related cases were divided. By infection route, 23 imported cases and 100 additional cases of transmission in local communities were identified.
  In term of ages, sex, and vaccination status, 63.4% (78 cases) were between 20 and 59 years of age, 57.7% (71 cases) were female, which marked a slightly higher than male, and 54.5% (67 cases) were unvaccinated. Asymptomatic at diagnosis were 24.4% (30 cases), and the main symptoms of Omicron VOC were fever 32.5% (40 cases), sore throat 30.9% (38 cases), cough 29.3% (36 cases), headache 20.3% (25 cases). There were no cases exhibiting severe symptoms and no deaths up to now. The average incubation period was 4.2 days (2-8 days), and the serial interval was 2.8 to 3.4 days. As a result of the initial analysis of the epidemiological properties of the 123 cases of the omicron VOC, this report will share information with the public and related experts. This report recommended that the KDCA continuoue to monitor and respond to the omicron VOC.

  Tuberculosis (TB) is an infectious disease caused by the bacillus Mycobaterium tuberculosis. It was the 13^th leading cause of death worldwide in 2019. The aim of this report was to review World Health Organization’s (WHO) Global Tuberculosis Report 2021. According to the report, in 2020, an estimated 9,87 million (127 per 100,000 population) people suffered from TB incident cases worldwide. It caused 1.49 million (19 per 100,000 population) deaths. The WHO’s report presented data from 215 countries and territories. Among them, the Republic of Korea (ROK) ranked 95^th in TB incidence and 109^th in TB mortality. This marked the ROK as the “Organization for Economic Co-operation and Development” country with the highest incidence (49 per 100,000 population) and the third-highest TB mortality rate (3.8 per 100,000 population). To accelerate the goal of ending TB by 2030, the WHO recommended intensifying multisectoral action on the broader determinants of TB. Pursuant to the ROK's global commitment, the Korea Disease Control and Prevention Agency will continue to implement the policy measure to improve TB prevention management.

  The aim of this study was to investigate the weight distribution and obesity-related factors of adolescents from the Daegu-Gyeongbuk region by using the results of the Korean Youth Risk Behavior Web-based Survey (KYRBS) data and to provide information on the weight management of adolescents in the region. We analyzed data from the 2018-2020 KYRBS of 167,618 middle and high school students, of which data of 17,260 adolescents (males: 8,943, females: 8,317) in Daegu-Gyeongbuk were included. In this region, the prevalence of obesity had increased from 11.8% in 2018 to 13.5% in 2020, showing slightly higher results than the national prevalence of obesity, which increased from 10.8% in 2018 to 12.1% in 2020. When analyzing weight control behaviors by weight category, similar results were shown both in Daegu-Gyeongbuk and nationwide. Among the behaviors, the proportion of adolescents trying to "lose weight" was the highest in normal, overweight, and obesity groups. In particular, female students comprised a significantly higher percentage of those who tried to "lose weight" than male students, even though they were in the normal weight group. When comparing the general characteristics of adolescents in Daegu-Gyeongbuk by obesity, both male and female students in the obesity group, were older and had a higher educational grade than those from the normal weight group. The obesity group was associated with lower household income and was more likely to report poorer perceived health status. Multiple logistic regression with adjustment for general factors showed that relative to normal weight, obesity was significantly associated with gender (female vs. male; OR [95% CI]: 1.00 vs. 1.92 [1.74-2.12]), grade (middle school vs. high school; OR [95% CI]): 1.00 vs 1.35 [1.10-1.64], and muscle strengthening exercise (No vs Yes; OR [95% CI]: 1.00 vs 0.65 [0.57-0.73]). Based on these results, we suggest that proper weight management and education are necessary with regards to these personal characteristics for the healthy growth of adolescents in Daegu-Gyeongbuk.
