We all know that tuberculosis is infectious, and the main way of infection is through the respiratory system. Some people may ask, when is the infectivity of tuberculosis the highest? How is tuberculosis infected? Next, we will introduce these one by one for everyone.

Tuberculosis does not have a regular period of high infectivity. Among tuberculosis patients, only those with tuberculosis detected by the microscope in sputum (i.e., so-called ‘smear-positive’ and ‘culture-positive’ patients) have infectivity. ‘Smear-positive’ and ‘culture-positive’ patients are medically referred to as sputum producers, and the tuberculosis they have is called ‘open tuberculosis’, which is the causative agent of tuberculosis. You can go to the infectious disease department of the hospital to check whether you have infectivity. The infection of tuberculosis usually occurs before discovery and diagnosis, that is, when there are no significant symptoms detected, the infectivity is high. After immediate treatment, the infectivity of tuberculosis quickly weakens and diminishes.

How is tuberculosis infected?

The causative agent of tuberculosis is mainly the sputum-producing tuberculosis patients, especially the undetected sputum producers are the most risky causative agents. However, after effective treatment, the infectivity can be significantly reduced or eliminated.

Aerobic infections: When patients with sputum cough or sneeze, the droplets transmitted and the dry sputum containing bacteria turn into floating dust in the air, which may be inhaled by others and cause infection.

Gastrointestinal infections: Using utensils used by patients with sputum without disinfection or eating leftover food from such patients may cause infection due to dietary exposure.

Next, I strongly recommend two types of drugs for everyone:

Cat’s claw capsules: Used for resolving swelling, reducing inflammation, and for treating scrofula, lymph node tuberculosis without ulceration, and can also be used for tuberculosis.

Lifupred capsules: Indicated for pneumonia, tuberculosis, and respiratory diseases.
