Active ImageEl noma, o cancrum oris, es una infección de gangrena de acción rápida que destruye las membranas de moco de los tejidos orales y faciales. Se desconoce la etiología exacta de ello, pero con mayor frecuencia ocurre en los niños `malnutridos` que viven en las áreas con el saneamiento deficiente.

El noma no se ha notificado ampliamente en la América Latina y el Caribe, pero aproximadamente 140.000 nuevos casos se diagnostican anualmente. La tasa de mortalidad es cerca de 8,5%. Es sumamente prevalente en África subsahariana.
