Tuberculosis
More than two weeks of coughing, positive latent tuberculosis test result – Misconceptions and truths about tuberculosis.
Diseases that have not yet disappeared.
South Korea still has a significant number of tuberculosis cases. If you experience a persistent cough for more than two weeks, along with symptoms like low-grade fever, night sweats, and weight loss, it's important to get tested for tuberculosis.
- The government covers most of the costs for testing and treatment (through public health centers and medical institutions).
- Treatment involves taking multiple medications consistently for six months – stopping midway can lead to drug-resistant tuberculosis, making it much more difficult to treat.
- After about two weeks of starting treatment, the infectiousness decreases significantly, allowing a return to normal activities.

It says I have a positive latent tuberculosis test, but does that mean I have tuberculosis?
Many people are surprised when they receive a notification of latent tuberculosis during health checkups or other screenings.
- Latent tuberculosis means that the bacteria is dormant in the body, and you are not a tuberculosis patient and it is not contagious.
- However, in some individuals (about 10%) over their lifetime, it can reactivate into active tuberculosis, so preventive treatment (taking medication for 3-4 months) may be recommended.
- Preventive treatment is also eligible for national support. It is not a condition that you are obligated to report to your workplace.

Frequently asked questions
My family member has been diagnosed with tuberculosis. Should I get tested too?
Yes. Family members who live together are eligible for contact tracing examinations (chest X-ray + latent tuberculosis test), which can be received free of charge at the public health center.
Is it okay to drink alcohol while undergoing tuberculosis treatment?
Tuberculosis medications can put a strain on the liver, so abstaining from alcohol is generally recommended during the treatment period. Regular liver function tests are performed and treated as needed.
