| | Immunodeficiency |
 | | Acquired immunodeficiency is most commonly caused by disease, such as malnutrition, sickle cell anemia, cancers, and diabetes; infections, such as measles, bacterial and fungal infections, and cytomegalovirus; or as a side effect of certain drugs and therapies used in the treatment of chronic disease. |
 | | It is common for children with immunodeficiencies to develop thrush, a fungal infection of the mouth, and other infections of the skin and mucous membranes in the eyes, mouth, and genital area. |
 | | Immunodeficiency disorders are diagnosed through blood tests, which are studied for the presence of immune components such as antibodies, lymphocytes, and phagocytes. |
