Why can untreated Fasciolopsis buski infections become especially serious in children?

Untreated infections of the trematode Fasciolopsis buski can become especially serious in children because heavy infestations lead to general body weakness and fluid retention.1

When these parasites attach to the small intestine using ventral suckers, the sites of attachment can ulcerate and form abscesses. In children, the resulting systemic effects of a heavy parasite load are particularly dangerous, making prompt diagnosis and treatment with medications such as praziquantel essential.1
