Anti-tuberculosis treatment must be given in full course; if the medication is stopped halfway, the disease may recur and re-treatment with anti-tuberculosis therapy may become difficult. Experiments have proved that sputum tuberculosis bacillus test is positive if the patient is newly suffering from tuberculosis treated for the first time. If a full course of treatment is given, the cure can be as high as 99% or even 100%. However, if the drug is stopped halfway, it may lead to the invasion of tuberculosis bacilli into the human body is not completely killed, resulting in a relapse of the disease, is because the tuberculosis bacilli are very stubborn, after entering the human body can exist in the human body’s macrophage and macrophage outside the macrophage cells. The macrophage is a kind of immune cell of the human body, for the invasion of the human body, can be eliminated by swallowing the things that are discharged out of the body. The tuberculosis bacilli that multiply very vigorously outside the macrophage can be easily killed by isoniazid, rifampicin, streptomycin, so at this time the symptoms of tuberculosis patients, such as coughing, fever, night sweats will disappear. At this time the patient may think he is cured and stop treatment, but the TB bacteria parasitized in the cells or lung tissues grow very slowly and are not completely killed. When the body’s resistance drops, it will take advantage of the opportunity to make tuberculosis recur, so the patient must adhere to the medication, the full course of treatment, the full course of medication, in order to make the macrophage inside and outside of the tuberculosis bacilli are all eliminated, in order to achieve a complete cure, and to prevent the recurrence of tuberculosis purposes.
