Risk factors
By Mayo Clinic staffITP can occur in anyone at almost any age, but these factors increase your risk:
- Your sex. Women are about twice as likely to develop ITP as men are.
- Recent viral infection. Many children with ITP develop the disorder after a viral illness, such as mumps, measles or a respiratory infection.
