Not exactly. Bone tuberculosis is mostly noncommunicable. In the majority of the cases, a healthy person cannot acquire bone tuberculosis from an infected person. Even a study confirms that bone tuberculosis is non-communicable until a healthy person has come in contact with infected body fluids or pus.
When bone tuberculosis occurs inside the lungs, the condition is called pulmonary tuberculosis. In rare cases, pulmonary tuberculosis spreads out of the lungs to reach organs or bones. In this case, mycobacterium tuberculosis bacteria spread outside the lungs to reach the bone through the blood or lymph.
Besides this, bone tuberculosis can also occur outside the lungs. This condition is called Extrapulmonary Tuberculosis (EPTB). EPTB is common among people with weak immunity due to acquired immunodeficiency syndrome (AIDS).
The Narayana Health Hospital website also suggests that the improper treatment of tuberculosis can cause bone tuberculosis soon. It is possible only when the treatment has not killed all the bacteria in the body, and some move to the blood vessels and lymph to reach the bone. In conclusion, bone tuberculosis is rare and can only occur when the immune system cannot control the bacterial cell growth.
