Idiopathic thrombocytopenic purpura (ITP), also known as primary immune thrombocytopenic purpura and autoimmune thrombocytopenic purpura, is defined as isolated thrombocytopenia with normal bone marrow and the absence of other causes of thrombocytopenia. The 2 distinct clinical syndromes manifest as an acute condition in children and a chronic condition in adults.

In chronic ITP (adults), the female-to-male ratio is 2.6:1. More than 72% of patients older than 10 years are female.
In acute ITP (children), distribution is equal between males (52%) and females (48%).

Mortality rates vary based on the age of the patient and the type of botulism. Foodborne botulism carries an overall mortality rate of 5-10%. Wound botulism carries a mortality rate that ranges from 15-17%. The risk of death due to infant botulism is usually less than 1%.
