Second, how is tuberculosis spread and how to control it?

Tuberculosis is a respiratory infectious disease. Mycobacterium tuberculosis will protrude from the respiratory tract when patients with pulmonary tuberculosis cough, sneeze and speak loudly, and float in the air, especially those with cough symptoms, which is the most contagious and the main source of infection. Healthy people may be infected with tuberculosis if they inhale mycobacterium tuberculosis floating in the air. ?

The most effective measure to control the spread of tuberculosis is to find patients as soon as possible and carry out active and effective treatment. Kill germs through drugs, reduce and eliminate infectivity. In addition, patients should not cough, sneeze or speak loudly in front of others. Cover your nose and mouth with a handkerchief when necessary, don't spit everywhere, and keep the doors and windows of the room open to keep the indoor ventilation and fresh air. ?

Third, the examination and diagnosis of tuberculosis.

Tuberculosis is a Class B infectious disease under the centralized management of the state. If you have suspicious symptoms of tuberculosis, you should immediately go to the local tuberculosis prevention and treatment institution for examination and treatment. The examination and diagnosis methods of pulmonary tuberculosis include tuberculin test (PPD), chest film, X-ray film and sputum smear microscopy.

Sputum smear examination is the main method and means of diagnosis and differential diagnosis, making treatment plan and evaluating curative effect of pulmonary tuberculosis patients. Sputum smear examination needs to send three sputum samples, namely night sputum, morning sputum and instant sputum. Inhale deeply and cough deeply when taking sputum.
