How Tuberculosis Is Caused How to Treat Tuberculosis

Tuberculosis is a chronic respiratory infection caused by infection with Mycobacterium tuberculosis. Spread mainly by droplets, when a person coughs, sneezes or talks, they scatter droplets containing tuberculosis bacteria into the air and can be suspended for several hours, causing infection when inhaled by others.

1. Source of infection

1. Bacteria excreted: Bacterial excretion refers to pulmonary tuberculosis patients with positive acid-fast staining on sputum smear without obvious clinical symptoms, which is the main source of infection;

2. Inactive pulmonary tuberculosis: refers to patients with stable lesions on X-ray examination and negative acid-fast staining on sputum smear, which is also an important source of infection.

2. Mode of transmission

Mycobacterium tuberculosis can be transmitted by airborne droplets and can become susceptible to infection if you are in close contact with an infected person. It can also be transmitted through other routes, such as the gastrointestinal tract and mucocutaneous membranes, but it is rare.

3. Susceptible populations

People of any age can be infected with Mycobacterium tuberculosis, but infants and young children and older people are more susceptible to infection because they are immunocompromised.

Fourth, pathogenesis

After the Mycobacterium tuberculosis invades the body, it grows and multiplies in the body and produces toxins, which leads to lesions in various organs throughout the body, such as pulmonary tuberculosis if the lungs are involved. If left untreated, it may lead to aggravation of the condition and in severe cases, it can be life-threatening.

It is recommended to pay attention to personal hygiene in daily life and avoid visitingabortionDense areas so as not to increase the risk of infection. At the same time, it is also necessary to exercise appropriately, which can enhance self-immunity and help prevent the occurrence of diseases.
