Objectives:
Tuberculosis (TB) is an airborne infectious disease that is preventable and curable. In the Republic of Korea (ROK), it is designated as a Class 2 infectious disease and is managed. This study aims to describe the incidence and epidemiological characteristics of TB cases in ROK in 2024.
Methods:
The TB incidence in ROK was compiled based on the annual report on the notified tuberculosis in 2024 and the microdata from 2022 to 2024. The TB incidence rate was calculated using the mid-year registered resident population, the number of foreign residents, and the population covered by medical insurance.
Results:
In 2024, the number of TB cases in the ROK was 17,944 (35.2 cases per 100,000 population), a decrease of 8.2% from 2023 (n=19,540, 38.2 cases per 100,000 population). Among TB cases aged 65 years and older, 10,534 were reported in 2024, a decrease of 6.9% from 2023 (n=11,309). However, the proportion of TB cases aged 65 and older increased to 58.7% (an increase of 0.8% point compared with 2023), continuing an upward trend since 2000. The number of TB cases who are foreigners in 2024 was 1,077, a decrease of 2.7% from 2023 (n=1,107), but the proportion of foreign TB cases increased to 6.0% from 5.7% in 2023.
Conclusions:
In 2024, the number of TB cases in the ROK decreased by 8.2% compared to 2023. However, the proportion of elderly TB cases aged 65 and older and foreign TB cases increased. Korea Disease Control and Prevention Agency keeps implementing TB prevention and control programs for high-risk groups and vulnerable populations to address emerging challenges.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
