Primary treatment TB refers to patients who are found for the first time and have not received any anti-tuberculosis drug treatment, or patients who have been treated with irregular and unreasonable anti-tuberculosis treatment after the discovery of TB, but the course of treatment does not exceed 1 month. However, as long as the patient actively cooperates with the anti-TB doctor and insists on effective, reasonable and complete chemotherapy, the infectiousness can disappear within 2-4 weeks and the cure rate can be over 95%. The key is to comply with medical advice, obey management, complete the course of treatment, and strive for a complete cure.
