人体抵抗病原微生物感染的免疫功能,包括天然免疫及获得性免疫两个方面。天然免疫是由人体的某些组织的解剖结构和某些生理机能所构成的防御机能。它的防御作用快,一遇到病原微生物即能发挥作用,是机体防御病原微生物的第一道防线。保护好这道防线,坚固这道防线,是有效地预防传染病的一个重要方面。 面对SARS(传染性非典型肺炎)这种呼吸道急性传染病的可能再次袭来,我们应该怎么办? The body’s immune function against pathogenic microorganisms, including both innate immunity and acquired immunity. Natural immunity is the defensive function of the anatomy and certain physiological functions of certain tissues of the body. Its defensive effect is quick, and once it encounters pathogenic microorganisms, it can play a role as the first line of defense against pathogenic microorganisms in the body. To protect this line of defense and strengthen this line of defense is an important aspect of effective prevention of infectious diseases. In the face of SARS (SARS), an acute respiratory infectious disease may hit again, what should we do?
