Some roundworms infect humans and can live in the intestines, tissues, or other parts of the body. Examples include Ascaris lumbricoides, hookworms, and Strongyloides species.
Human roundworm infections can be acquired through routes such as contaminated soil, food, or water, depending on the species. Treatment varies according to the particular parasite.
