  The aim of this article was to investigate CRE cases and outcomes in Korea between 2018 and 2019 to provide guidance to the Korea Disease Control and Prevention Agency (KDCA) for future planning. The KDCA first conducted CRE surveillance in December 2010. The surveillance was monitored by only a small number of hospitals and then converted to mandatory surveillance from June 3, 2017 by all medical institutions. This article investigated CRE cases as collected in the KDCA’s reporting system and found that 27,323 CRE cases were reported: 11,954 cases at 723 medical institutions in 2018 and 15,369 cases at 831 medical institutions in 2019. The cases were analyzed by year, species, age, and carbapenemase-producing Enterobacteriaceae (CPE). Findings indicated that CRE increased from 11,954 in 2018 to 15,369 (25.8%) in 2019, with K. pneumoniae the most common of the CRE strains. In terms of types of hospitals, reports at long-term care hospitals increased from 4% (517 cases) in 2018 to 7% (1,077 cases) in 2019, and reports of CRE cases aged 70 or older accounted for the largest percentage. The CPE ratio among CRE cases increased from 49.8% in 2018 to 57.8% in 2019 (5,962 → 8,887 cases, 49.0% increase). To better assess and plan for the full burden of CRE, measures should be taken to prevent the spread of CRE.

  Hemorrhagic fever with renal syndrome (HFRS) is a feverish disease caused by hantavirus infection that occurs mainly in autumn in Korea. The primary aim of this review was to analyze the 2017-2019 results of laboratory tests for HFRS to find improvements in the present antibody diagnostic method. HFRS antibody diagnostics is required both acute and convalescent phase serum to confirm an increase in antibody titer. In the last 3 years, 86.3% of HFRS tests were requested only for acute phase serum, but not for convalsecent phase serum. Since most of the primary single serum samples were submitted to laboratory, a 98.4% level of test result was pending. To address limitations of the IFA test, we developed the ELISA. The IgM ELISA for antibody test of HFRS was expected to provide rapid and sensitive results by detecting IgM antibodies from single serum samples in the acute phase. Furthermore, the results of the HFRS IgG avidity test-based ELISA could provide scientific evidence for the 1:512 standard of antibody titer of IFA test. The developed ELISA kit will also be used by Public Health and Environmental Research Institutes (PHERIs) will be effectively used in the diagnosis of HFRS in the future.
