What clinical presentation is associated with Ascaris lumbricoides infection?

Ascaris lumbricoides, commonly known as the giant roundworm, is one of the most prevalent human parasites globally. When an infection occurs, it can lead to various clinical presentations, particularly due to the large size of the adult worms, which can reach lengths of over 30 cm.

Intestinal obstruction is a significant complication associated with Ascaris lumbricoides infections. The worms can accumulate and form a mass, especially in children, leading to blockage of the intestine. This can result in symptoms such as abdominal distension, pain, nausea, and vomiting, and may require surgical intervention if not addressed promptly.

While severe abdominal pain can occur due to the presence of these worms, it is more typically a symptom of obstruction rather than a standalone consequence of the infection. Likewise, fever and chills are not characteristic of Ascaris infections, as they are more commonly associated with infections due to bacteria or other parasites. Skin rashes do not typically occur in Ascaris infections, unlike some other parasitic infections where skin manifestations might be evident.

Overall, intestinal obstruction represents a direct and serious consequence linked to the presence of a heavy burden of Ascaris lumbricoides.
