People with latent TB transmission are not quarantined. Tuberculosis is mainly caused by infectious TB patients spreading Mycobacterium tuberculosis resistant bacilli through respiratory droplets to infect close contacts in the surrounding area. Since the bacilli are more fragile when they are separated from the human body, especially in a dry and hot environment, the activity of the virus is more likely to be lost and is not very harmful. Moreover, after the human body is infected with Mycobacterium tuberculosis resistant bacilli, the immune system can remove most of the bacteria, so it is not easy for widespread transmission to occur. Therefore, people with hidden transmission of TB do not need to be isolated, and only need to wear a mask, take good personal protection, and do not spit. If you suspect that you are infected with Mycobacterium tuberculosis resistant bacilli, no matter whether you have symptoms or not, it is best to consult a doctor in time, complete the relevant examinations, make a clear diagnosis, and then treat the disease as soon as possible.
