The harm of natural epidemic diseases to humans

Human health is related to many factors, so if everyone wants to stay healthy, they must stay away from natural epidemic diseases. Once this disease infects humans, there will be serious epidemics and the harm to the body is also serious. The following is a detailed introduction so that you can have a comprehensive understanding of the harm of natural epidemic diseases to the human body.

1 Humans generally lack specific immunity to these diseases

Natural epidemic diseases exist originally in animals and cause them to become sick or not. Humans generally lack specific immunity to these diseases, and once infected, they are usually difficult to control and easily spread, especially newly emerging infectious diseases. Judging from the infectiousness of SARS in 2003, this pattern is consistent with the view that SARS originated from animals.

2 Once the immune response is initiated, it may cause serious pathological damage to the body

Since the antigens of these pathogens are new to humans, once the body's immune response is initiated after infection, the immune response may cause serious pathological damage to the body. Looking back at the SARS epidemic in 2003, the patients' clinical course was very serious, especially in every newly emerging epidemic area, where a number of critical cases appeared in large numbers.

3. When you are not vigilant, you are easily helpless.

Since natural epidemic diseases often exist in a specific environment, there has been a long period of contact between animals and pathogens, and a certain dynamic balance has been reached between animals and pathogens. Therefore, this specific environment appears calm on the surface, which makes humans relax their vigilance and they may be helpless once they are infected. When people go to fields, reservoirs, and streams outdoors, they are often mesmerized by the "peaceful" nature and enter this natural environment at will. Even after the disease occurs, this aspect is still ignored. In the late 1950s, a middle school in Guangzhou had a painful lesson: a student was infected with Leptospira after going to the suburbs, but due to lack of vigilance, he delayed treatment.

The harm of natural epidemic diseases to humans. After fully understanding the above introduction, I believe you have understood the harm to humans. After understanding the harm of natural epidemic diseases to humans, you must pay attention to it, stay away from animals, and don’t touch animals, so as to keep yourself away from the harm of this disease.
