Infections caused by carbapenem-resistant Enterobacterales (CRE) – one of the most feared antibiotic-resistant “superbugs” – are rising at the fastest pace ever recorded in South Korea.
The number of cases this year so far has already surpassed the total number of cases in 2024.
According to the Korea Disease Control and Prevention Agency (KDCA), 44,930 CRE infections have been reported as at Dec 1, a 6.1% increase from the 42,347 cases documented in all of 2024. This marks the highest figure since nationwide monitoring began in 2018, with consistent upward trend observed in the past seven years.
CRE infections occur when Enterobacterales, a common family of gut bacteria, develop resistance to carbapenems, a class of antibiotics considered one of the last lines of defence.
Since CRE became part of mandatory nationwide surveillance in June 2017, cases have risen steadily each year: from 5,717 reports in 2017 to 11,954 in 2018; 15,369 in 2019; 18,113 in 2020; 23,311 in 2021; 30,548 in 2022; and 38,405 in 2023.
The health authorities say the surge shows how the fight against infectious disease has fundamentally shifted.
“The era when we only worried about new pathogens is already over,” one orthopaedics expert said.
“Drug-resistant bacteria are transforming the future landscape of infectious disease.”
Patients in healthcare settings are at most risk for CRE. Bacteria typically spread in healthcare settings through direct or indirect contact with infected patients or contaminated equipment.
Antibiotic misuse is a key driver of resistance, and once infected, patients often face limited treatment options.
Health authorities warn that CRE infections not only prolong hospitalisation and raise treatment costs, but also pose growing socio-economic risks.
The World Health Organisation classified antimicrobial resistance as one of the top 10 global public health threats in 2019.
In response, the KDCA said it is preparing the Third National Antimicrobial Resistance Management Plan for 2026 to 2030, aimed at reducing antibiotic use, preserving treatment effectiveness and strengthening infection prevention.
