Whether children with tuberculosis will heal themselves varies from person to person: 1, some of the older children or children with normal immune function, after the body is infected with Mycobacterium tuberculosis, the body’s immune system is activated and will kill the invading Mycobacterium tuberculosis, part of the lesions in the body will be absorbed, dissipated or calcified, and can heal themselves, which is a very common clinical phenomenon. This is a very common clinical phenomenon, and sometimes the calcified foci are found on physical examination, but they are not aware of it. 2. There are also children with primary or secondary immunodeficiency, and after the combination of pulmonary tuberculosis, the symptoms are usually more severe and often manifest as severe tuberculosis, including systemic disseminated tuberculosis, tuberculous pleurisy, and even easily combined with bacterial infection, which is very difficult to treat and will not heal on its own.
