"Ezinma lay shivering on a mat beside a huge fire that her mother had kept burning all night. "It is iba.""

In the Igbo culture, the word "Iba" is translated to "fever." This usually refers to the fever that comes from malaria. Malaria is traditionally transmitted by mosquitoes. Its symptoms consist of a cycle of chills, fever, sweating and pain. Malaria fevers were frequently cured by the Igbo with medicine made from leaves, grass, and bark.
