What is the difference between old pulmonary tuberculosis and general pulmonary tuberculosis? These are two states of tuberculosis, one is called active tuberculosis, and the other is called stable tuberculosis. Tuberculosis is another manifestation of stable tuberculosis or active tuberculosis. Refers to people who have suffered from tuberculosis and are cured after standardized treatment by doctors and hospitals, and may leave scars, pulmonary nodules or calcified lesions. Known as tuberculosis, some people have mild symptoms or few lesions after getting tuberculosis, and their autoimmune function is activated. If they fight the disease, they will heal themselves, and finally they may leave small scars or calcification in their lungs. It's called old tuberculosis.

The other is general pulmonary tuberculosis or active pulmonary tuberculosis, which refers to pulmonary tuberculosis, for example, which has obvious inflammation and pathological changes recently, or is in the process of recovery, also known as active pulmonary tuberculosis. Because active tuberculosis is active, it means that there are mycobacterium tuberculosis, so the body needs treatment.

What is completely different is that there is no difference between these two types of tuberculosis patients and normal people, just like there was a wound on the skin, which turned into a scar after healing. This scar has no influence except for a little influence on a better life. Tuberculosis is a truth. After the scar, it has no effect on the lungs. It has no symptoms and lives like a normal person. But active tuberculosis must be hospitalized.

Old tuberculosis shows that the patient has been infected with Mycobacterium tuberculosis before, and has improved without special treatment and anti-tuberculosis treatment, and achieved self-healing; Or tuberculosis that has been clearly diagnosed before, after standardized and systematic treatment, is completely cured without any infectivity and does not need medical intervention again. Tuberculosis is a special infectious disease. After the disease has improved or recovered, chronic lesions, tuberculosis fibrous lesions or calcification often remain in the lungs. Calcification is generally no problem, because calcification is a hard pathological state and will not develop further. If it is a fibrous lesion, it will be very troublesome, because the fibrous lesion is the fibrous tissue around the lesion, which may contain residual bacteria.
