The dangers of spitting

Spitting is uncivilized because sputum contains many germs, such as bacteria, viruses, etc. If a patient with tuberculosis spits Mycobacterium tuberculosis is easily contained in the sputum of patients, and the bacteria are easily transmitted into normal people through the respiratory tract, causing the spread of tuberculosis and affecting public health.

Sputum is the secretion of the respiratory tract, and normal people do not cough up sputum. Only people with respiratory diseases will secrete a large amount of sputum when they are infected by foreign pathogenic bacteria. Sputum contains a variety of viruses, which are easily transmitted through droplets and can be transmitted to healthy people. Therefore, do not spit anywhere. In addition, be sure to wear a mask when going out and avoid going to crowded places.

Phlegm is the secretion of the respiratory tract, and healthy people generally have no phlegm. However, if you have a respiratory disease, you will produce a lot of sputum after being infected by pathogenic microorganisms. The sputum spit out by the patient is equivalent to the "culture medium" for bacteria. Thousands of germs will "reside" in a mouthful of sputum.
