Princess Shireen Baratheon caught greyscale as an infant and survived, but the ordeal left half of her face disfigured by the disease.
In the books Edit
In the A Song of Ice and Fire novels, greyscale generally affects children, especially in cold damp climates. The victims are left disfigured but become immune to the grey plague, the rarer mortal form of the affliction. The wildlings consider people who survive greyscale unclean.
Greyscale isn't the same thing as leprosy, as the effects are quite different. Still, the greyscale disease is dreaded in Westeros and Essos much as leprosy was in the real-life Middle Ages. A large area around the ruins of Chroyane in the Free Cities is even used as a large-scale leper-colony for those who have contracted greyscale.
