Spring is here, everything is reviving, flowers and willows are green, and spring is in full swing. However, you can often see the rush of pedestrians, men, women and children, there are always people inadvertently issued a “click”, followed by a mouthful of yellow phlegm, people see more than disgust. Especially when you walk on the road, see large and small, spotted with sputum, you have to look down around these nauseating sputum, not to mention how awkward it is. There are at least nearly twenty diseases transmitted by the respiratory tract, and mainly through droplets into the respiratory tract infected with disease, of which sputum is the culprit carrying pathogenic microorganisms. In patients with cavitary tuberculosis, one milliliter of sputum contains 1 million to 100 million tuberculosis bacteria, and these pathogenic bacteria survive for a very long time and can easily be transmitted to others through various means. For example, if someone walks on the floor with a trolley case or a child plays on the floor, the sputum will contaminate the object and your hands. There is also a way to spread the sputum containing disease-causing bacteria over time, and when it dries up, it floats in the air with the dust and can cause disease after being inhaled by healthy people. In short, spitting is a stereotypical habit that harms both others and oneself. In fact, the reason is very simple, and our air contains a large number of pathogenic microorganisms have a relationship, in layman’s terms, our air quality is too poor, too dirty, in addition to exhaust pollution, many people spit is also a very important reason. Western developed countries attach great importance to environmental health, especially the management of spitting is very strict, spitting on the ground to impose heavy fines. In Hong Kong, the fine for spitting is 1500 HKD. Singapore’s punishment for spitting includes education, fines, imprisonment, flogging and other means. Whether you are a Singaporean or a foreigner, you will be fined RMB 2,500 for spitting in Singapore. As a result, the incidence of respiratory diseases is low in countries with good sanitation. If we all take environmental sanitation as a major issue for the benefit of the country and the people, we should consciously do not spit, do not urinate or defecate anywhere, do not litter, control our pets, put their poop into the garbage cans, and maintain the public environment as if it were our own home. Then our country is not only famous for its vast territory and long history, but also for its beautiful environment and hygiene. We are proud to be Chinese in the world. It is always said that we should improve the health of our people. “No spitting” is one of the most important measures. If everyone can take the initiative to maintain environmental hygiene, those few people who want to try to destroy environmental hygiene will be opposed by everyone, and they will feel that spitting is a stereotype that is disgraceful and despised and spurned by everyone like a rat crossing the street. Only in this way can our environment be maintained in good condition. Everyone will be able to enjoy the benefits of an elegant environment and will not keep getting sick with the flu or other respiratory diseases. For the sake of your health and the health of others, I once again make a loud appeal: Don’t spit!
