Is bone tuberculosis contagious

summary

A very good friend of mine suffered from bone tuberculosis secondary to pulmonary tuberculosis. He just finished the operation yesterday, and now he is recuperating in the hospital. My mother asked me to have a check-up, saying that the disease would be infectious. Let me be careful, and I'm a little worried. Today, let me learn from you whether bone tuberculosis can be infectious.

Is bone tuberculosis contagious

First: if there is bone tuberculosis alone, then daily contact will not be infectious. Tuberculosis is mainly caused by respiratory tract infection, and then transmitted to other organs of the body through lymph nodes and blood system, collectively referred to as extrapulmonary tuberculosis, which accounts for about 15% of tuberculosis.

Second: the spread of tuberculosis is the spread of tuberculosis in the air by coughing or sneezing when patients with tuberculosis are in the infectious period. Healthy people will be infected when they inhale the droplets containing tuberculosis. Therefore, if it is only patients with bone tuberculosis, daily life contact will not spread tuberculosis.

Third: bone tuberculosis is not contagious. 95% of bone tuberculosis is secondary to pulmonary tuberculosis. Mycobacterium tuberculosis can not directly invade bone and joint. Therefore, bone tuberculosis is not infectious. Only after bone tuberculosis causes abscess to burst, the tubercle bacillus in the pus is not handled properly, which may cause infection.

matters needing attention

Because tuberculosis is difficult to treat, it is also difficult to treat. At the same time, we should also pay attention to adequate rest and appropriate outdoor activities. In addition, in life must be clear what symptoms of bone tuberculosis, in order to achieve early detection and early treatment of the disease.
