According to the International Union of Immunological Societies, more than 150 primary immunodeficiency diseases (PIDs) have been characterized.[2] However, the number of acquired immunodeficiencies exceeds the number of PIDs.[3]
It has been suggested that most people have at least one primary immunodeficiency.[4] Due to redundancies in the immune system, though, many of these are never detected.
