Which symptom is often associated with infected Ascaris?

Abdominal pain is a common symptom associated with infection by Ascaris lumbricoides, the roundworm. These parasites can inhabit the intestines of a host, leading to discomfort and various gastrointestinal disturbances. As the worms grow and reproduce, they can cause blockage or irritation of the intestinal lining, resulting in abdominal cramping or pain.

While other symptoms can be associated with parasitic infections or other types of helminth infections, abdominal pain is particularly characteristic for Ascaris due to the worms' size and their active movement within the intestines. Severe diarrhea, intense itching, and fever with chills may relate to other conditions or types of helminth infections, making abdominal pain the more specific and relevant symptom for Ascaris infections.
