Natural immunity refers to that when pathogenic microorganisms enter into the human body, such as the upper respiratory tract and intestinal tract, natural immunity is like sentinels. At first glance, it is not the inherent substances of the body, but has a clearing mechanism. It plays a role through mononuclear megaphagocyte system, and fever may appear in clinical practice. That is to say, the first-line defense system is activated. If the first-line defense system is not blocked, the pathogen will enter the body and then be released. At this time, the natural immunity will be very limited, relying on the specific immunity or acquired immunity. At this time, the specific attack will have a strong attack on the cells infected by the pathogenic microorganism, and eliminate the infection of these pathogenic microorganisms. Of course, this process will also lead to the occurrence and occurrence of the disease Therefore, it is very important to keep a good immune state and resist the infection of virus and microorganism. But there is no specific drug that can really increase the immunity. We still emphasize that a balanced diet, suitable exercise and a good mental state are all very important to keep a good immune state. Therefore, it is suggested that the public should not blindly eat all kinds of health care products and drugs, because there may be the risk of drug-induced injury, or to improve the overall immune level through a balanced diet, a good mentality and appropriate exercise. #Come on, Hubei, Wuhan, hold on#
