Diseases from A to Z
A disease is an abnormal condition that affects the human body of an organism. It is often construed as a medical condition associated with symptoms and signs. It may be caused by factors originally from an external source, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases. In people, "disease" is often used more broadly to refer to any condition that causes pain, dysfunction, distress, and social problems to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. Diseases usually affect people, but not only physically, also emotionally, as contracting and living with many diseases can alter one's perspective on life, and their personality.
