Who Is At Risk for Aplastic Anemia?

Aplastic anemia is a rare, but serious blood disorder. In the United States, about 500–1,000 people develop this type of anemia each year. The disorder is two to three times more common in Asian countries.

People of all ages can get aplastic anemia. However, it's most common in adolescents, young adults, and the elderly. Men and women are equally likely to have it.

Your risk for aplastic anemia is higher if you have:

• Been exposed to toxins
• Taken certain medicines or had radiation or chemotherapy treatment (treatments for cancer)
• Certain infectious diseases, autoimmune disorders, or inherited conditions
