Answer

The annual incidence of aplastic anemia in Europe, as detailed in large, formal epidemiologic studies, is 2 cases per million population. [41] Aplastic anemia is thought to be more common in Asia than in the West. The incidence was accurately determined to be 4 cases per million population in Bangkok, [42] but based on prospective studies, it may actually be closer to 6 cases per million population in the rural areas of Thailand. This increased incidence may be related to environmental factors, such as increased exposure to toxic chemicals, rather than to genetic factors, because this increase is not observed in people of Asian ancestry who are living in the United States.
