Tuberculosis may invade various organs of the human body, but it mainly invades the lung, which is called tuberculosis. All year round can be onset, 15 to 35 years old youth is the high incidence of tuberculosis peak age. The incubation period was 4-8 weeks. 80% of them occurred in the lung, and other parts (cervical lymph, meninges, peritoneum, intestine, skin, bone) can also be secondary infection. Respiratory transmission is the main way of infection. Is tuberculosis asymptomatic? Let's have a look.

Is tuberculosis asymptomatic?

The incubation period of tuberculosis is 4-8 weeks. To sum up, in addition to the clinical manifestations of tuberculosis, the above corresponding tests should be done for the diagnosis of tuberculosis. The clinical manifestations of the incubation period are not obvious, and it is impossible to confirm whether there is tuberculosis. Only after the incubation period can the diagnosis be made, and the time is more than 4-8 weeks.

Routine tests for tuberculosis include smear test, which is to make smear of sputum or body fluid from other parts of the patient, and detect the negative and positive of the patient under the microscope. X-ray examination can not only detect tuberculosis early, but also diagnose the location, scope, nature, development and effect of the sign. Tuberculin test, positive tuberculosis infection, but not necessarily sick. If the dilution is positive in skin test, it often indicates that there is active tuberculosis in the body. Negative results indicate no tuberculosis infection.

Tuberculosis is divided into primary, blood group dissemination and secondary. The main clinical manifestations of tuberculosis are fever, cough, expectoration and blood in sputum. The clinical manifestations of gastric tuberculosis are very inconsistent, some asymptomatic or very mild, some similar to chronic gastritis, gastric cancer, most like ulcer disease. The most common symptoms of liver tuberculosis are fever and fatigue. The clinical manifestations of intestinal tuberculosis are not obvious in the early stage, most of them have slow onset and long course of disease.

Tuberculosis is a disease transmitted by Mycobacterium tuberculosis through respiratory tract. It is mainly transmitted by patients' coughing, sneezing and droplets when speaking loudly. Therefore, in order to avoid infection, we must develop good health habits.
