What age group is most commonly affected by ITP in children?

The most commonly affected age group for immune thrombocytopenic purpura (ITP) in children is frequently found among those aged 2-4 years. This condition, characterized by a low platelet count leading to increased bleeding and bruising, often presents in early childhood. The reasons for this prevalence in the 2-4 year age range may include factors such as the presence of viral infections that can trigger the immune response, leading to the condition.

While infants under 1 year can experience ITP, and some cases may extend into adolescence and adulthood, the highest incidences are documented within the early childhood age group. This aligns with clinical observations and epidemiological data that show a distinct peak incidence in preschool-aged children, positioning them as the most affected demographic for ITP.
