The 2018 National Guideline for Tuberculosis Control, which was published by the Korea Centers for Diseases Prevention and Control (KCDC), mandates conducting an epidemiological survey among close contacts of active tuberculosis patients at public institutions such as schools. In the procedure for these surveys, the tuberculin skin test (TST) is mandated as the screening test for latent tuberculosis infection in elementary school students. However, several guidelines recommend using the interferon-gamma releasing assay (IGRA) for contacts aged over 5 years with a Bacillus Calmette–Guérin vaccination history. The main reason for this is that IGRA has a higher specificity and lower false positive rate than TST. In addition, IGRA requires only a single visit to draw blood and the results are available within 24 hours. These advantages could promote cooperation from both parents and students in conducting these surveys. Thus, these findings regarding the benefits of IGRA for surveys of close contacts at elementary schools should be incorporated into the KCDC guideline.
Summary
Korean summary
집단시설에서의 결핵환자 발생시 수행하는 역학조사 지침에는 잠복결핵감염자의 검진을 위해 초등학생에게 투베르쿨린 피부반응검사 (TST)를 시행하도록 되어 있다. 그러나, 6세 이상의 초등학생들은 필수적으로 BCG 예방접종을 받았다는 점과, 역학조사 수행의 협조 등을 고려할 때 TST 대신 인터페론감마 분비검사 (Interferon-gamma releasing assay, IGRA)를 우선 시행하는 것이 보다 더 근거중심적, 가치중심적 으로 타당하다.

Objectives
In the Republic of Korea (ROK), the notified incidence of tuberculosis in foreign-born individuals (NITFBI) has increased recently, as has the rate of multidrug-resistant (MDR) and rifampicin-resistant (RR) tuberculosis in foreigners staying in the ROK. As Jeju Province in ROK has a no-visa entry policy, control programs for NITFBI should be consolidated. The aim was to evaluate the status of NITFBI, with a focus on the distribution of MDR/RR tuberculosis by nationality.
Methods
Data on tuberculosis incidence in individuals born in Jeju Province and in foreign-born individuals were extracted from the Korean Statistical Information Service of Statistics Korea, and the Infectious Disease Surveillance Web Statistics of the Korea Centers for Disease Control and Prevention, respectively.
Results
Among all notified incident cases of tuberculosis, the proportion of NITFBI increased from 1.46% in 2011 to 6.84% in 2017. China- and Vietnam-born individuals accounted for the greatest proportion of the 95 cases of NITFBI. Seven cases of MDR/RR tuberculosis were found, all involving patients born in China.
Conclusions
In Jeju Province, ROK, NITFBI might become more common in the near future. Countermeasures for controlling active tuberculosis in immigrants born in high-risk nations for tuberculosis should be prepared in Jeju Province, since it is a popular tourist destination.
Summary
Korean summary
제주도는 국제자유도시를 천명하면서, 30일 무비자 입국을 허용하고 있다. 이에 따라 외국인 결핵환자가 증가하고 있다. 제주도 결핵 신환자 신고 중 외국인의 분율은 2011년 1.46%에서 2017년 6.84%로 증가했으며, 약제 내성에 있어서는 총 7건이었다. 향후 제주도내 외국인 결핵환자 신고수가 증가하는 가운데 약제내성 결핵환자도 증가할 수 있음을 예측하고, 외국인에 대한 활동성 결핵관리 정책을 보완하고 지침을 강화할 필요가 있다.
