Is tuberculosis still contagious after taking medicine?

Whether a person with pulmonary tuberculosis is more contagious after taking anti-tuberculosis drugs needs to be determined on a case-by-case basis. If the patient's condition is controlled, it is less contagious; However, if the patient does not take the medication as prescribed or the condition is not effectively controlled, the contagiousness may still be strong.

1. Weak infectivity: If the patient has undergone standardized anti-tuberculosis treatment, the sputum bacteria examination is negative, the clinical symptoms disappear, and the imaging shows that the lesion absorption improves, etc., the infectivity is relatively small or no longer infectious;

2. Strong infectivity: Some patients have poor anti-tuberculosis treatment due to various reasons, such as self-discontinuation of drugs, poor medication compliance, drug resistance, etc., resulting in the prolongation of the disease, and even serious complications and complications, at this time, it is more contagious.In addition, although some patients have received regular anti-tuberculosis treatment, a large number of tuberculosis bacilli can still be excreted during the treatment, resulting in infection of the surrounding population.

It is recommended that patients with pulmonary tuberculosis must strictly follow the doctor's guidance for systematic and regular treatment, and should not stop, reduce or change the dose at will, so as not to affect the efficacy and not be conducive to the recovery of the disease. At the same time, we should also pay attention to protective measures in daily life, avoid sharing daily belongings with others, and regularly review and understand our own situation.
