Is talking to tuberculosis contagious?

Talking to tuberculosis patients is likely to cause infection, because tuberculosis is transmitted through the respiratory tract, that is, through the air. If you talk to patients at close range, without wearing a mask protection, it is possible to infect tuberculosis. Therefore, when in contact with patients, it is best to wear a mask, and to maintain a certain distance, preferably one meter away. Also to prevent patients from talking loudly to others, sneezing, coughing, patients had better be isolated, given isolation treatment. After anti-tuberculosis treatment, the infectivity of patients is obviously reduced. After treatment, many patients can be cured, the prognosis is good, so tuberculosis, to active treatment.
