Shitala, sometimes Sheetala: Goddess of Disease in Hinduism.
Shitala is a Hindu god who is both a pestilence deity and a healer.
She's the one who gave us smallpox and a slew of other
illnesses, and she's the only one who can heal them.
She abhors filth and pollution, and people who want her
graces must be ritually washed, both physically and spiritually.
