Disease is an abnormal condition affecting the body of an organism. It is often construed to be a medical condition associated with specific symptoms and signs. It may be caused by external factors, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases. In humans, "disease" is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, and/or death 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 not only physically, but also emotionally, as contracting and living with many diseases can alter one's perspective on life, and their personality.
- [Diseases] crucify the soul of man, attenuate our bodies, dry them, wither them, shrivel them up like old apples, make them as so many anatomies.
- Robert Burton, The Anatomy of Melancholy (1621), Part I, scene 2. Memb. 3. Subsect. 10.
- A bodily disease which we look upon as whole and entire within itself, may, after all, be but a symptom of some ailment in the spiritual part.
- Nathaniel Hawthorne, The Scarlet Letter (1850), Chapter X.
- As man, perhaps, the moment of his breath,
Receives the lurking principle of death,
The young disease, that must subdue at length,
Grows with his growth, and strengthens with his strength.
- Alexander Pope, An Essay on Man (1733-34), Epistle II, line 133.
- But just disease to luxury succeeds,
And ev'ry death its own avenger breeds.
- Alexander Pope, An Essay on Man (1733-34), Epistle III, line 165.
- O, he's a limb, that has but a disease;
Mortal, to cut it off; to cure it, easy.
- Diseases desperate grown,
By desperate appliance are reliev'd,
Or not at all.
- This apoplexy is, as I take it, a kind of lethargy, an't please your lordship; a kind of sleeping in the blood, a whoreson tingling.
- Before the curing of a strong disease,
Even in the instant of repair and health,
The fit is strongest; evils that take leave,
On their departure most of all show evil.
- I'll forbear;
And am fallen out with my more headier will,
To take the indispos'd and sickly fit
For the sound man.
