I'm task to do a research on any particular disease that is either common or uncommon in the cultural perspective that when people are affected by it, beliefs may arises from it such as to why, how and when this disease is affecting a particular group or an individual. The beliefs may be in the form of spirits, nature etc, and the practices that are used to combat this particular disease.
Placing it in a cultural perspective when modern technologies were not yet available to either identify and point out it's origin.
