Pink disease (acrodynia, erythredema), named because of the skin colour of the sufferers, was once a serious disease of infants and young children. It appeared in the western world about the turn of the 20th century, particularly in English-speaking countries. Babies turned bright pink and became ill, intolerant to light, lost their appetites, and became utterly miserable, often rejecting even their mothers. Some lost fingers and toes from gangrene and, on average, 7% of sufferers died.
