St. Agatha of Sicily, a 3rd-century martyr, is patron of nurses, as is St. Camillus de Lellis, a 16th-century founder of a religious order dedicated to hospital care. St. Camillus's red cross on his habit was one of the inspirations for the modern Red Cross symbol. He was declared the patron of the sick, nurses, hospitals, and physicians by Pope Leo XIII in 1886.
St. John of God, whose religious order (the Brothers Hospitallers) operates hospitals worldwide, is also invoked by nurses and those who care for the sick. His feast day is March 8.

Saint Agatha is the primary patron saint of nurses. Their feast day is February 5.
A patron saint is a holy man or woman canonized by the Church whose life and heavenly intercession are considered especially powerful for particular needs, groups, or situations. Catholics ask patron saints to intercede — to pray to God on their behalf — drawing on the doctrine of the Communion of Saints.
To ask for a patron saint's intercession, Catholics typically pray directly to the saint, saying something like: "Agatha, pray for us." You may also light a candle, attend Mass on their feast day, or make a novena — nine days of consecutive prayer — asking for their help before a particular need.
