Animal bones excavated with earthenware from the shell mound at the Jeju Jongdali 1819 archeological site, where three consecutive chronological layers covering the Neolithic (B.C. 15C-B.C. 10C), early Tamra, and late Tamra periods have been identified, were morphologically classified. The majority of the bones from all three periods were broken or split. The major fauna of the mammalian bones in all periods were Cervus spp., Sus scrofa, and Bos taurus. In the early and late Tamra periods, bones of small animals including Mustela sibirica coreana, Meles meles, Rodentia, and Aves were also found in small number. The excavated bones were from all parts of the animal bodies, including head, trunk, forelimb, and hindlimb. Collectively, these findings suggest that the major fauna from the Neolithic to late Tamra periods consisted of Cervus spp., Sus scrofa, and Bos taurus and that the fauna was dissected and carried to the shell mound site after hunting. Information from the bone remains in the shell mound are useful data for study of the wildlife and domestic animals living during the prehistoric period of Jeju Island.

OBJECTIVES: Because effective decolonization options are not available, and treatment options are limited, carbapenem-resistant Enterobacterales (CRE) constitute increasingly threatening nosocomial pathogens. To prevent CRE-associated transmission and ensure patient safety, healthcare personnel and everyone in contact with CRE-infected patients must implement stringent infection control practices. This report describes a CRE outbreak, possibly related to a caregiver at a long-term care facility (LTCF), and presents a new surveillance model to improve the infection control of CRE in Seoul, Korea. METHODS: The Seoul Metropolitan Government surveillance system identified an outbreak of CRE in an LTCF in 2022. We obtained data on the demographic characteristics and contact histories of the inpatients, medical staff, and caregivers. To isolate the inpatients and employees exposed to CRE, we used rectal swab samples and environmental sampling during the study period (May-December 2022). RESULTS: We identified 18 cluster cases (1 caregiver and 17 inpatients) and 12 sporadic cases with CRE, and conducted a complete 197-day follow-up of all cases in the LTCF’s isolation wards. CONCLUSIONS This investigation demonstrated that our surveillance model and targeted intervention, based on the cooperation of the municipal government, public health center, and infection control advisory committee, effectively contained the epidemic at the LTCF. Measures to improve the compliance of all employees in LTCFs with infection control guidelines should also be adopted.

Background: Although the evidence of treatment for coronavirus disease 2019 (COVID-19) changed rapidly, little is known about the patterns of potential pharmacological treatment during the early period of the COVID-19 pandemic in Korea and the risk factors for ineffective prescription. Methods: Using claims data from the Korean National Health Insurance System, this retrospective cohort study included admission episodes for COVID-19 from February to December 2020. Ineffective antiviral prescriptions for COVID-19 were defined as lopinavir/ ritonavir (LPN/r) and hydroxychloroquine (HCQ) prescribed after July 2020, according to the revised National Institute of Health COVID-19 treatment guidelines. Factors associated with ineffective prescriptions, including patient and hospital factors, were identified by multivariate logistic regression analysis. Results: Of the 15,723 COVID-19 admission episodes from February to June 2020, 4,183 (26.6%) included prescriptions of LPN/r, and 3,312 (21.1%) included prescriptions of HCQ.Of the 48,843 admission episodes from July to December 2020, after the guidelines were revised, 2,258 (4.6%) and 182 (0.4%) included prescriptions of ineffective LPN/r and HCQ, respectively. Patient factors independently associated with ineffective antiviral prescription were older age (adjusted odds ratio [aOR] per 10-year increase, 1.17; 95% confidence interval [CI], 1.14–1.20) and severe condition with an oxygen requirement (aOR, 2.49; 95% CI, 2.24–2.77). The prescription of ineffective antiviral drugs was highly prevalent in primary and nursing hospitals (aOR, 40.58; 95% CI, 31.97–51.50), public sector hospitals (aOR, 15.61; 95% CI, 12.76–19.09), and regions in which these drugs were highly prescribed before July 2020 (aOR, 10.65; 95% CI, 8.26–13.74). Conclusion Ineffective antiviral agents were prescribed to a substantial number of patients during the first year of the COVID-19 pandemic in Korea. Treatment with these ineffective drugs tended to be prolonged in severely ill patients and in primary and public hospitals.
