Roundworms vs. Hookworms: What’s the Difference?

What are the common symptoms of roundworm and hookworm infections in humans?

Roundworms and hookworms are parasitic worms that can cause serious health problems in both humans and animals. Both roundworms and hookworms cause similar symptoms, but they differ in many ways. Understanding the differences between these two types of worms can help you diagnose and treat infection more effectively.


Roundworms are elongated, segmented worms, also known as nematodes or intestinal roundworms. They have a long tail and a small head, and they can grow up to 2 cm in length. Millions of people are infected by roundworms worldwide, and they are the most common worm infection in the United States.

Roundworms most commonly infect the intestine and can cause respiratory, digestive, and other symptoms. They can be spread through contact with feces, contaminated soil, or infected food or water. Roundworms can also enter the body through the skin or by being swallowed.


Hookworms are another type of parasitic worms. Unlike roundworms, these worms attach to the intestinal walls and feed on the host’s blood. Hookworms are much smaller than roundworms, and they are about 1 cm in length. Hookworm infestations are more common in tropical regions, but they are found around the world.
