The problem of the enteric carrier has exercised many penetrating minds and has evoked a large amount of work, thought, discussion, and compassion, and a sizable literature over the last half-century. Many conflicting views have been put forward in recent years regarding the efficacy of treatment. In Scotland, where standards of health and hygiene are high, the relatively small nidi of enteric carriers probably represent the last stronghold of a disease which in former years has taken its toll of human life and suffering. In the world at large, however, and particularly in the relatively underdeveloped countries, the problem must still be a vast one. The carrier's condition is a danger not only to the community but to himself in the form of restriction, anxiety, and painful and even potentially fatal disease.
