Abstract
|
|
|
The Korea Centers for Disease Control and Prevention (KCDC) conducted a tuberculosis (TB) screening pilot project in 2019 in local regions. The aim was to develop screening and treatment protocols for strengthening TB management among
homeless people. Homeless people have a high risk of developing and spreading TB to socially and economically vulnerable populations. Out of the 500 people targeted for the project, 483 participated. As a result of chest X-ray examinations (482) and sputum examinations (141), 3 TB patients (621 people per 100,000 population) were found. This is about 12 times higher than the incidence of TB in the general population (51.5 per 100,000 people, based on 2018 data), and about 4 times higher than the incidence of TB in the elderly population, which accounts for 46 percent of the country's new TB patients (163 per 100,000 people, based on 2018 data). The results of each test were abnormal findings rate of chest X-ray 20.1% (97/482), smearpositive 0.7% (1/141), culture-positive 2.1% (3/141), tuberculosis-polymerase chain reaction(PCR) test-positive 2.1% (3/141), Xpert MTB/RIF test-negative 100% (1/1), and the rapid resistance and drug susceptibility tests were both resistant 66.7% (2/3). The 3 patients who were diagnosed with TB were medical care recipients and ineligible for health insurance. They were 40-50-year-old Korean males with histories of smoking, drinking, and underlying diseases. As patients with no TB history, 2 patients were diagnosed with extensive drug resistance and isoniazid monoresistance TB. For the early detection and successful treatment of individuals living on the periphery of society, which is a blind spot for TB prevention management, it is essential to secure access to examinations with mobile chest X-ray equipment and to create a treatment support environment by providing housing and living expenses for confirmed TB patients. The KCDC plans to expand and promote TB screening projects nationwide for the homeless and residents of Chok Bang in 2020 and will strengthen the treatment support system, including housing costs and food support linked to local governments' welfare projects.
