Tuberculosis, commonly known as consumption, is a chronic infectious disease caused by Mycobacterium tuberculosis infection that can affect multiple organs, with pulmonary involvement, or TB, being the most common. Tuberculosis is an infection caused by the invasion of Mycobacterium tuberculosis and is a chronic and slow-onset infectious disease. It is a chronic and slow-onset infectious disease. If diagnosed promptly and treated appropriately, most patients can be cured clinically. Patients with bacilli are an important source of infection. The common manifestations of tuberculosis are low fever in the afternoon, weakness, loss of appetite, emaciation, and night sweats. Patients with TB also have chest pain, chest tightness, cough and sputum, which is mucopurulent when secondary infection occurs. Due to capillary dilatation and small vessel damage caused by inflammatory lesions or rupture of blood vessels in the lung cavity, patients with pulmonary tuberculosis may have varying degrees of hemoptysis, and some patients may experience irritability, nervousness, struggling to sit up, chest tightness and shortness of breath, cyanosis and other symptoms, which should be rescued immediately. If the lung lesions progress to disseminate, patients often have irregular high fever and women may also have menstrual irregularities. If the tuberculosis bacillus spreads to the skull and brain, it can cause tuberculous meningitis with symptoms of meningitis such as fever, headache, vomiting, and in severe cases, impaired consciousness, coma, or even death. Human infection with TB bacilli does not necessarily cause disease, but may cause clinical morbidity when the body’s immunity, resistance, or cell-mediated metabolic response is increased. Tuberculosis requires prompt treatment. In summary, when similar symptoms appear, early medical consultation is needed to clarify the diagnosis and to provide regular, full course of anti-tuberculosis treatment to avoid delaying the disease.
