"Dr. S. Tamilarasan examines a fellow Untouchable [a member of the lowest Hindu castes] at a busy clinic he and his father run in Devakottai, a city in the southern state of Tamil Nadu. Patients commonly suffer from malnutrition, typhoid, and tuberculosis. At one of only a few medical facilities in the area, the two doctors serve many higher caste patients, a case of necessity outweighing prejudice."
