What are the close contacts of tuberculosis?
People who are in close contact with tuberculosis patients are likely to inhale a large number of tuberculosis due to close contact with the patient, and therefore are more susceptible to the disease than others, and should be given special attention. Including the following types of people:

• The family members of the patient's relatives, or those who live together for a long time;
• A colleague who shares the office with the patient and a patient who lives in a ward;
• Intimate contact with the patient, such as inhaling the tuberculosis discharged by the patient while kissing or hugging.

Anyone who is in close contact with tuberculosis patients will get tuberculosis?
Not necessarily. This depends mainly on the following factors:

(1) Whether there is tuberculosis in sputum: depends on whether there is tuberculosis in the sputum and droplets coughed out by tuberculosis patients, only patients with tuberculosis can spread tuberculosis (not all patients with tuberculosis, there are tuberculosis in the sputum bacteria).

(2) Amount and time of inhaled tuberculosis: When a patient with infectious tuberculosis is coughing or sneezing, a large amount of tuberculosis is discharged. If close contact with the patient, a large amount of tuberculosis will be inhaled, and with the contact time The amount of prolonged inhaled tuberculosis will also increase.

(3) The virulence of tuberculosis and the resistance of the infected person: If the tuberculosis is highly toxic or the body's resistance is not high, it is easy to develop tuberculosis. If the body's resistance is high enough, the virulence of tuberculosis is weak, and our body's defense system can kill tuberculosis and will not develop disease. Therefore, not all infected sources may be infected, and infected people may not always have the disease. Some people with lower resistance, such as the elderly, patients with malignant tumors, and patients taking immunosuppressive agents, are more likely to develop tuberculosis.
