病原体可以借助哪些途径进入人体? 俗话说:“病从口入”。其实,传染病并不都是通过口感染的。概括起来,它有六条传播途径: 1.空气飞沫传播:所有的呼吸道传染病都通过这种方式传播。当病人呼吸、谈话、咳嗽和打喷嚏时,从鼻咽部排出大量含有病原体的飞沫。这些飞沫悬浮在空气中,就通过这样被污染的空气传播疾病。容易感染的人与病人密切接触便可直接吸入这种含有病原体的飞沫而受到感染。在外环境中抵抗力较弱的病原
Pathways by which pathogen can enter the body? As the saying goes: “Disease from the mouth.” In fact, infectious diseases are not all infected through the mouth. To sum up, it has six routes of transmission: 1. Air droplets spread: all respiratory diseases are transmitted in this way. When the patient breathes, talks, coughs and sneezes, a large amount of droplets containing pathogens are expelled from the nasopharynx. The droplets are suspended in the air and spread the disease through such contaminated air. Infectious individuals can be directly infected with the droplets containing the pathogen by intimate contact with the patient. Weak pathogen in the external environment
