Ascariasis is an infection caused by a roundworm called Ascaris Lumbricoides. It affects the small intestine and is known to be the most common type of roundworm infection.
The infection happens when the roundworms use the body as a host to mature larvae into adult worms. It takes them two to three months to grow up to 30 centimeters long. Additionally, adult worms can reproduce inside the body, and they can stay inside the body for about a year or two.
This infection commonly occurs in children living in tropical and subtropical regions. Higher rates of this infection are recorded in areas with poor hygiene and sanitation.
