Intestinal tuberculosis is a type of tuberculosis, second only to pulmonary tuberculosis, and is a chronic, specific infection of the intestinal tract caused by Mycobacterium tuberculosis. Many people are afraid to hear about TB and are always afraid of being infected. We all know that TB is an infectious disease, but in general, intestinal TB is not contagious, at least in some special cases. We all know that tuberculosis is an open tuberculosis and can be transmitted through the respiratory tract by sputum, coughing, sneezing, etc. The tuberculosis bacilli are located in the intestine and there is only one way to discharge the bacilli, which is defecation. Only when a person relieves the feces with TB bacilli can it be transmitted, and the chance of that is very small, so intestinal TB is generally not contagious. However, if intestinal tuberculosis spreads through bloodstream and neighboring organs, and pulmonary tuberculosis develops secondary to it, and if the tuberculosis bacilli are present in the sputum during the active stage, then it is contagious in this case and needs to be noted. As mentioned above, intestinal tuberculosis is not contagious in general, but if pulmonary tuberculosis develops secondary to intestinal tuberculosis and the bacilli are present in the sputum during the active phase, it is contagious to a certain extent. The sputum, saliva and utensils of patients with intestinal tuberculosis must be handled separately to prevent infection. However, general contact is not contagious. Tuberculosis can be cured with standard treatment, so it is recommended to seek standardized medical treatment in a timely manner.
