瘧疾發作瘧疾的一次典型發作表現為寒戰、高熱和出汗退熱三個連續階段。發作是由紅細胞內期的裂體增殖所致，當經過幾代紅細胞內期裂體增殖后，血中原蟲的密度達到發熱閾值，如間日瘧原蟲為10-500個/µl血，惡性瘧原蟲為500-1300個/µl血。紅細胞內期成熟裂殖體脹破紅細胞后，大量的裂殖子、原蟲代謝產物及紅細胞碎片進入血流，其中一部分被巨噬細胞、中性粒細胞吞噬，刺激這些細胞產生內源性熱原質，它和瘧原蟲的代謝產物共同作用于宿主下丘腦的體溫調節中樞，引起發熱。隨著血內刺激物被吞噬和降解，機體通過大量出汗，體溫逐漸恢復正常，機體進入發作間歇階段。由于紅細胞內期裂體增殖是發作的基礎，因此發作具有周期性，此周期與紅細胞內期裂體增殖周期*。典型的間日瘧和卵形瘧隔日發作1次；三日瘧為隔2天發作1次；惡性瘧隔36-48小時發作1次。若寄生的瘧原蟲增殖不同步時，發作間隔則無規律，如初發患者。不同種瘧原蟲混合感染時或有不同批次的同種瘧原蟲重復感染時，發作也多不典型。瘧疾發作次數主要取決于患者治療適當與否及機體免疫力增強的速度。隨著機體對瘧原蟲產生的免疫力逐漸增強，大量原蟲被消滅，發作可自行停止。

瘧疾的再燃和復發瘧疾初發停止后，患者若無再感染，僅由于體內殘存的少量紅細胞內期瘧原蟲在一定條件下重新大量繁殖又引起的瘧疾發作，稱為瘧疾的再燃。再燃與宿主抵抗力和特異性免疫力的下降及瘧原蟲的抗原變異有關。瘧疾復發（relapse）是指瘧疾初發患者紅細胞內期瘧原蟲已被消滅，未經蚊媒傳播感染，經過數周至年余，又出現瘧疾發作，稱復發。關于復發機理目前仍未闡明清楚，其中子孢子休眠學說認為由于肝細胞內的休眠子復蘇，發育釋放的裂殖子進入紅細胞繁殖引起的瘧疾發作。惡性瘧原蟲和三日瘧原蟲無遲發型子孢子，因而只有再燃而無復發。間日瘧原蟲和卵形瘧原蟲既有再燃，又有復發。

A typical episode of malaria malaria is a three-step period of chills, fever and sweating. Attack is caused by the proliferation of red blood cells caused by the proliferation of several generations, when several generations of red blood cells within the proliferation of the proliferation of protozoa protozoa to reach the threshold of fever, such as vivax malaria 10-500 / μl blood, falciparum malaria Protozoa for the 500-1300 / μl blood. Red blood cells within the mature schistosome ruptured red blood cells, a large number of merozoites, protozoa metabolites and red blood cell debris into the blood flow, part of macrophages, neutrophils phagocytosis, stimulate these cells produce endogenous pyrogen Quality, it and the metabolites of malaria parasite on the host hypothalamus in the body temperature regulation center, causing fever. With the blood stimuli are swallowed and degraded, the body through a lot of sweating, body temperature gradually returned to normal, the body into the intermittent stage of attack. As the proliferation of erythrocyte scoliosis is the basis of the attack, so the onset of periodic, this cycle and erythrocyte scoliosis cycle consistent. Typical of vivax malaria and ovoid malaria incident every other day; three malaria for 2 days 2 episodes; falciparum malaria 36-48 hours attack 1 times. If the parasitic parasite proliferation is not synchronized, the onset interval is irregular, such as the initial patients. Different species of malaria parasite infection or different batches of the same type of malaria parasite infection, the attack is also more atypical. The number of malaria episodes is mainly dependent on the treatment of patients with appropriate and the speed of immunity to enhance the body. With the body of malaria parasites produced by the gradual increase in immunity, a large number of protozoa were eliminated, the attack can be self-stop.

Malaria reburning and relapse after the initial onset of malaria, the patient without re-infection, only because the body of a small amount of red blood cells within the period of Plasmodium in a certain condition to reproduce and cause a large number of malaria attacks, known as malaria reburning. Reburning is associated with a decrease in host resistance and specific immunity and an antigenic variation of Plasmodium. Malignant relapse (relapse) refers to the initial malaria patients with red blood cells within the Plasmodium has been eliminated, without mosquito-borne infection, after several weeks to years, but also malaria attack, said recurrence. The mechanism of recurrence is still unclear, in which the sporozoite dormancy theory suggests that due to resuscitation of dormants in hepatocytes, developmental release of merozoites into erythrocyte reproduction caused by malaria. Plasmodium falciparum and Plasmodium falciparum without delayed sporozoites, and thus only reburning without recurrence. Plasmodium falciparum and oviparous flames both reburning and recurrence.
