What reason is cutaneous tuberculosis caused?

Skin tuberculosis is caused by the direct invasion of Mycobacterium tuberculosis into the skin or by the dissemination of Mycobacterium tuberculosis in other organs through blood or lymphatic system. Mycobacterium tuberculosis is not particularly virulent,

The virulence of Mycobacterium tuberculosis is not particularly strong. Only 5% to 10% of the people get sick after Mycobacterium tuberculosis infection. The incidence rate of skin tuberculosis is similar to that of tuberculosis, and is more common in developing China and poor people.

Mycobacterium tuberculosis is the main pathogenic bacteria of skin tuberculosis. Mycobacterium bovis and Bacillus Calmette Guerin (attenuated Mycobacterium bovis) can occasionally cause skin tuberculosis. Tuberculosis is mainly transmitted by droplets, but also by inhalation, ingestion and vaccination.

The working and living environment should be well ventilated to reduce the concentration of TB in the air; Pay attention to personal hygiene, do not spit everywhere, reduce the spread and reproduction of tuberculosis. Strengthen physical exercise. Tuberculosis can survive in the human body for a long time. Once the body's resistance is reduced, tuberculosis will multiply rapidly, leading to disease. Therefore, at ordinary times should pay attention to strengthen physical exercise, reasonable diet, in order to enhance immunity.
