Algerian popular belief attributes any illness to the action of a bad djinn.

Evidence

The djinn (plural djnoun) is a spirit. He haunts the houses and the fields. Popular belief attributed to him an important role in all the phenomena of life: birth, circumcision, marriage, sickness, death. In the case of disease, any impairment of health was interpreted as the work of a bad djinn. — Frantz Fanon, A Dying Colonialism, 472
