Hello, according to the situation you described, tuberculosis is a respiratory infectious disease, which is caused by mycobacterium tuberculosis. Whether people living with pulmonary tuberculosis will be infected mainly depends on three factors. One is whether the patient is an active pulmonary tuberculosis patient, that is, whether live Mycobacterium tuberculosis is discharged from his lungs, the other is whether the sputum secretion discharged by the patient has been specially killed, and the last one depends on the resistance of susceptible people and whether they have been vaccinated with BCG. If you are vaccinated with BCG, you are already immune to tuberculosis and generally will not be infected.

Suggestion:

Hello, according to the situation you described, to sum up, in any case, if there are tuberculosis patients at home, it is better to take some appropriate preventive measures. The sputum spit out by tuberculosis patients should be disinfected in time, and the things used at ordinary times should be disinfected regularly. It is best to wear a mask at ordinary times. Active patients should be treated in isolation from time to time, and uninfected susceptible people should be vaccinated with BCG in time. I hope my answer can help you, thank you! ! !
