text: Both really  - malaria so named because in the old days they thought bad (damp) night air was what caused it.\n\nAnyway its related to zoology (study of animals) because the mosquito is what carries it and infect humans when they bite them. Not all mosquito's are carriers. Its also related to physiology (study of the mechanical, physical, and biochemical functions of living organisms) because it affects the human body severely.
