Amid the COVID-19 pandemic, vaccination coverage may decline due to limited accessibility to healthcare. We assessed the impact of the COVID-19 pandemic on vaccination coverage and the incidence of vaccine-preventable diseases (VPDs) in the Republic of Korea. National vaccination coverage of 10 essential vaccines administered to children between January-June 2019 and January-June 2020 was analyzed.

We investigated an outbreak of enterotoxigenic (ETEC) O159:H20 associated with the consumption of a tossed-noodle dish in a high school in 2016. Thirty-three ETEC strains isolated from clinical and food samples were genetically indistinguishable. The outbreak strains were resistant to third-generation cephalosporins and harbored a gene on a 97-kb self-transferable IncK plasmid.

- South Korea's National Antimicrobial Resistance Safety Control Program (NARSCP) ran from 2003 to 2013 to address antimicrobial resistance (AMR) through systematic research and funding strategies.
- The study analyzed 198 project reports from various health ministries, revealing a total funding of $18.3 million, with most research focusing on basic microbial research and surveillance.
- Findings indicated a significant increase in yearly funding and a need for more balanced research support that includes input from private and international sectors to effectively tackle AMR.
Article Synopsis
- * A total of 313 homeless individuals were tested for LTBI using two methods and for active TB through chest X-rays during a period from October 2009 to April 2010.
- * Results showed that 75.9% had LTBI and 5.8% had active TB, with LTBI rates in the homeless group being about five times higher than in the general population, indicating a significant public health issue that needs targeted intervention.
Increased tuberculosis burden due to demographic transition in Korea from 2001 to 2010.
Tuberc Respir Dis (Seoul)
March 2013
Background: Notified tuberculosis (TB) cases in Korea have not decreased over the last decade (2001-2010).
Methods: To clarify the reasons, we analyzed an annual report on notified tuberculosis patients and age-specific population drift in Korea.
Results: Compared to the age-specific notified TB cases between 2001 and 2010, distinctive features in notified TB cases and new cases increased markedly in people aged 45-54 years and in patients over 65 years old, whereas those between 15-34 years in 2010 decreased drastically.
Article Synopsis
- Mycobacterium bovis BCG is the only vaccine currently available for tuberculosis.
- The various strains of BCG used globally are derived from a family of daughter strains that have unique genetic traits.
- This report presents the complete genome sequence of the M. bovis BCG Korea strain, which will be utilized for vaccine production in Korea.
Article Synopsis
- The study analyzed medical records of 53,579 TB patients in Korea from 2008 to assess the epidemiology of TB and its treatment in private institutions.
- Among the analyzed cases, 29.2% were sputum smear positive, with new TB cases making up 73.1% and drug resistance rates at 5.3% for new cases.
- The findings revealed that out of the total TB patients, 66.4% were cured or completed treatment, highlighting the effectiveness of using health insurance data to understand TB status in the country.
Objective: To describe the radiographic findings of primary pulmonary tuberculosis (TB) in previously healthy adolescent patients.
Materials And Methods: The Institutional Review Board approved this retrospective study, with a waiver of informed consent from the patients. TB outbreaks occurred in 15 senior high schools and chest radiographs from 58 students with identical strains of TB were analyzed by restriction fragment length polymorphism analysis by two independent observers.
