What is the most common cause of a fistula in children?

Chronic PA abscess
Bacterial infection
Viral infection
Physical injury

The correct answer is: Chronic PA abscess

Fistulas are abnormal connections between two organs, vessels, or structures that are not normally in contact with each other. They can occur due to various reasons, such as inflammation, injury, or infection. However, when it comes to fistulas in children, the most common cause is a chronic PA abscess. This type of abscess is caused by a build-up of pus in the abdominal area, which can lead to the formation of a fistula. Bacterial and viral infections can also cause fistulas, but they are not as common in children as they are in adults. Physical injury, while it can cause a fistula, is not the most common cause in children.
