Every school has different rules. Although the state stipulates that tuberculosis patients must drop out of school, most schools have not implemented it.

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, especially tuberculosis infection. Bacterial secretions are an important source of infection.

The human body may not get sick after being infected with tuberculosis, but it may cause clinical diseases only when the resistance decreases or the cell-mediated allergic reaction increases. If it can be diagnosed in time and treated reasonably, most of them can be cured clinically.

The cause of disease

Mycobacterium tuberculosis belongs to the genus Mycobacterium of Actinomyces and Mycobacteriaceae, and it is a virulent acid-resistant bacterium. Mainly divided into human, cattle, birds, rats and other types. Human-type bacteria are the main pathogens, and bovine-type bacteria are rarely infected.

Drug resistance of tuberculosis can be formed by the development of congenital drug-resistant bacteria in the flora, or by using an anti-tuberculosis drug alone in the human body. Drug-resistant bacteria will cause difficulties in treatment and affect the curative effect.
