Mycobacterium tuberculosis positive can be cured in most cases with active treatment. Positive Mycobacterium tuberculosis indicates tuberculosis infection, which is the most specific way to confirm the diagnosis of tuberculosis, including intestinal tuberculosis, pulmonary tuberculosis, renal tuberculosis and so on. Chemotherapy is the basis of treatment, such as isoniazid, rifampicin and other first-line anti-tuberculosis drugs, kanamycin, amikacin and other second-line medicines, and there are also other surgical and symptomatic treatments and other ways. Most TB patients diagnosed at an early stage can be cured after receiving regular treatment. Only a few drug-resistant TB and immunocompromised patients are more difficult to treat and have a longer treatment cycle, and may develop severe disease. Those who are found to be positive for Mycobacterium tuberculosis are advised to consult a doctor in time and receive treatment under the guidance of a professional doctor to avoid delaying their condition.
