Disease: Malaria
Cause: 4 species of the protozoan, Plasmodium
Transmission: The Anopheles mosquitoes are the hosts that transmit the disease to humans during the blood-sucking process.
Symptoms: The different stages in the life cycle of the protozoan cause the different symptoms of the disease:
- When the pathogen first enters the blood, it travels to the LIVER CELLS, where it hides from the immune system. There, it multiplies rapidly, producing dozens of cells called merozoites

only very slowly. Treatment of sufferers includes using anti-malarial drugs such as quinine (effective against parasites in red blood cells), and primaquine phosphate (works in both blood and liver cells). Some strains of plasmodium are resistant however.
Prevention: Protective clothing, insect repellent, mosquito nets.
Control: Aims to keep incidence of disease to a minimum in population. Drugs to destroy vector, and parasite. Destroying vector's habitat. Vaccines against plasmodium. Genetic engineering of mosquitoes to resist parasite.
