Helminthes are parasitic worms that infect humans and are broadly classified into nematodes (roundworms), cestodes (tapeworms), and trematodes (flukes). They are common in areas with poor sanitation, inadequate hygiene, and limited access to clean water. The modes of spread vary according to the type of helminth. Many intestinal nematodes such as Ascaris lumbricoides and Trichuris trichiura spread through the fecal–oral route by ingestion of eggs present in contaminated food, water, or soil. Hookworms infect humans when larvae in contaminated soil penetrate the skin, usually through bare feet. Enterobius vermicularis (pinworm) spreads through direct person-to-person contact and contaminated surfaces. Cestodes like Taenia solium and Taenia saginata are transmitted through consumption of undercooked pork or beef containing larval cysts. Trematodes such as Schistosoma species spread through contact with freshwater contaminated with larval forms that penetrate the skin. Poor personal hygiene, open defecation, and improper disposal of human waste facilitate transmission. The signs and symptoms of helminthic infections depend on the species, worm burden, and the organs involved. Many infections are initially
