The Infectivity of Pulmonary Tuberculosis in Korean Army Units: Evidence from Outbreak Investigations.

Background: Tuberculosis (TB) causes substantial health burden to the Korean military. This study aims to assess the impact of infectious TB cases on close and casual contacts in the Korean Army settings based on contact investigation data.

Methods: Six Army units with infectious TB cases from September 2012 to May 2013 were enrolled in the study.

Occupational Risk of Latent Tuberculosis Infection in Health Workers of 14 Military Hospitals.

Tuberculosis (TB) is a known occupational risk to health workers. Identifying risk factors in health care settings is critical to the prevention of TB for health workers and patients. In 2014, we carried out a TB screening and survey for 902 health workers from 14 selected military hospitals to determine the prevalence rate of latent tuberculosis infection (LTBI) as well as occupational risk factors.

Boosted reaction on two-step tuberculin skin test among military personnel in South Korea, a setting with an intermediate burden of tuberculosis and routine bacille Calmette-Guerin vaccination.

This study was performed to estimate the rate of boosted reaction in the two-step tuberculin skin test (TST) and to evaluate the associated factors among military personnel of South Korea, which has an intermediate burden of tuberculosis (TB) and a routine bacille Calmette-Guerin (BCG) vaccination policy. Two-step TST was performed on 264 military personnel who did not have a history of close contact to TB. Subjects with a negative reaction to the first test of <10 mm had a second TST applied 1 week later on the other forearm.

The incidence of tuberculosis after a measles outbreak.

Among 53,974 cases of measles that occurred during the 2000-2001 outbreak in Korea, the incidence of tuberculosis following measles was 47 cases per 214,949.6 person-years, which was significantly lower than that in the general population (standardized incidence ratio, 0.73; 95% confidence interval, 0.

Tuberculosis among dislocated North Koreans entering Republic of Korea since 1999.

The collapse of North Korea's public health system has increased the development of tuberculosis (TB) in its populace. This study investigated the prevalence of active and latent TB infection (LTBI) in such people who have settled in the Republic of Korea since 1999. From 1999 to August 2006, 7,722 dislocated North Koreans entered the Republic of Korea and all were screened immediately for active TB.
