疟疾是疟蚊(按蚊)传播的。按蚊在吸吮疟疾病人血时,把血里的疟原虫也吸入体内。疟原虫就在蚊子的体内进行有性繁殖,其后代叫“子孢子”。蚊子在咬人吸血的时候,为了迅速把血吸到体内,就吐出一些唾液来防止血液凝固,这时候“子孢子”也就随着唾液进入人的血里。“子孢子”进入人体以后,很快就到达肝脏,在肝脏细胞里进行繁殖,成为“潜隐子”。以后,肝细胞被“潜隐子”胀破,大部分“潜隐子”钻进红血球里吸取营养,进行另一阶段的繁殖,而小部分“潜隐子”仍 Malaria is transmitted by Anopheles mosquitoes (Anopheles mosquitoes). Anopheles also inhale malaria parasites in the blood while sucking malaria. Plasmodium reproduces sexually in mosquitoes. Its descendants are called “sporozoites.” When a mosquito bites a person and sucks blood, in order to suck blood into the body quickly, he will spit out some saliva to prevent the blood from clotting. At this time, the “sporozoite” will enter the human blood with the saliva. When the “sporozoite” enters the body, it quickly reaches the liver and reproduces in the liver cells to become “hidden.” Later, liver cells were “hidden” to burst, most of the “hidden worms” drilled into the red blood cells to absorb nutrients and carry out another stage of breeding, while a small part of the “hidden sub-” still
