Which type of infection is not common in children?

Trichinosis is not commonly found in children compared to other types of infections listed. It is caused by consuming undercooked meat infected with the larvae of the Trichinella parasite, which is more frequently associated with adults who consume such contaminated products. In contrast, pinworm infections are highly prevalent in children, particularly those in school settings, due to the ease of transmission from person to person. Hookworm and tape worm infections also have certain life cycles and transmission modes that can affect children, especially in areas with poor sanitation or where certain food practices are common.

In summary, while pinworms, hookworms, and tape worms are relatively common in pediatric populations, trichinosis is significantly less common, making it the correct answer to this question.
