顾名思义,传染源指的是引起传染的来源。受到病原体感染的人和动物,不仅体内可以孳生和繁殖病原体,而且还可以主动地排出病原体,所以,只有受到病原体感染的人或动物,才可以起到传染源的作用。有人误以为吃了污染的食物或喝了污染的水以后,引起了细菌性痢疾,受到污染的食物或水就是传染源。 As the name implies, the source of infection is the source of the infection. People and animals infected with pathogens not only can breed and multiply pathogens in the body, but also proactively discharge pathogens. Therefore, only humans and animals infected with pathogens can act as sources of infection. Some people mistakenly think that after eating contaminated food or drinking polluted water, it causes bacillary dysentery. Contaminated food or water is the source of infection.
