Which toxic substance is responsible for the chills and high fever recurring every three to four days in malarial fever ?
Answer & explanation
Correct answer: option 2
The parasites
initially multiply within the liver cells and then attack the red blood cells
(RBCs) resulting in their rupture. The rupture of RBCs is associated with
release of a toxic substance, haemozoin, which is responsible for the chill
and high fever recurring every three to four days.
