What causes malaria?
Malaria is caused by protist pathogens that enter red blood cells and damage them.
What are the symptoms of malaria?
Symptoms include fevers and shaking when the protists burst out of blood cells.
How is malaria spread?
The vector is the female Anopheles mosquito, in which protists reproduce sexually. When the mosquito punctures the skin to feed on blood, the protists enter the human bloodstream via its saliva.
How can malaria be prevented?
Prevention methods include using insecticide-coated insect nets while sleeping, removing stagnant water to stop vectors breeding, and travellers taking antimalarial drugs to kill parasites that enter the blood.
