The statement that acquired red cell aplasias predominantly occur in childhood and are almost always transient is accurate. Acquired red cell aplasias, particularly in children, are often associated with viral infections, exposure to certain medications, or autoimmune conditions. In many cases, the underlying cause is transient, and most children will recover as the body clears the infection or as the medication is discontinued.

The context for understanding why this is true involves recognizing that, while red cell aplasias can occur in adults, they are more frequently diagnosed in pediatric populations. Many instances in children may resolve without long-term implications, reflecting their transient nature.

In contrast, other statements suggest chronicity or genetic links that do not align with the majority of cases observed in pediatric contexts. While some acquired red cell aplasias can be more persistent or have genetic components, this is not the predominant characteristic for the majority of cases seen in children.
