ICD-11

A disease caused by determinants arising after birth, in the antenatal period or genetically inherited factors leading to the inability of stem cells to generate new mature cells. This disease is characterised by low levels of red blood cells, white blood cells, and platelets. This disease may present with pallor, fatigue, dizziness, increased risk of infection or increased bruising or bleeding.

A condition occurring secondary to other disorders or via an auto-immune response directed to the bone marrow arising after birth. This disease is characterised by an almost complete absence of hematopoietic stem cells resulting in low levels of red and white blood cells and platelets. This condition may present with fatigue, chronic infections, dizziness, weakness, headaches, and episodes of bleeding, usually in the skin and mucous membranes.
