Health is defined as complete well-being in body, mind, and social interactions rather than just the lack of illness. A disease causes an abnormal condition or malfunction that impacts an organism's structure or functions and can result in pain, discomfort, or death for the affected person. Common disease-causing microorganisms include bacteria, viruses, protozoa, helminthes, and fungi.
