Another notable healer is Primrose Everdeen, who helps Mrs. Everdeen heal people. She is young, but she has gotten the blood of her healer mother and naturally had a great ability to heal people. After the bombing of District 12, when Gale collected more than 900 people and escaped out the forest, Prim and her mother set up a medical area and healed injured people who survived out of the fire. They had very few things to treat from, but they tried their best by gathering whatever they could from the forest.
Since the districts do not have official hospitals or doctors, a healer is their main source of medical care and is equivalent to a doctor. It is mentioned in Mockingjay that District 8 had a hospital in the rebellion but it is unknown whether there were actual doctors or healers there.
After Gale's whipping, when Mrs. Everdeen and Prim were healing him, Mrs. Everdeen remarked that it was lucky that they had snow for a snowcoat. When Katniss asked what she did in the summer, Mrs. Everdeen put on a weary face and replied: "Tried to keep the flies away."
