Hi doctor. My son was born in 1999. In November 2019, he went to the hospital for regular health check-ups and had a chest X-ray, the results were normal. Last week, when she went to the central hospital, she was diagnosed with tuberculosis. She was vaccinated against tuberculosis at birth, why is she still sick? I hope the doctor can help me. I would like to thank you.

Tuberculosis is an infectious disease that causes high mortality rates in the world, including Vietnam. Tuberculosis bacteria were discovered in 1982 by Robert Koch and until now scientists have discovered important characteristics of tuberculosis bacteria.

Tuberculosis is caused by bacteria called Mycobacterium tuberculosis, an infectious disease that causes many dangerous symptoms. In addition to the typical symptoms of the disease, the diagnosis of tuberculosis is based on the test for tuberculosis bacteria, which plays a decisive role.
