They have classified 3 types of worms that are parasitic and can infect human, animal and plants: Cestodes or tapeworm, Trematodes (schistosoma), and Nematodes or round worms, hookworm or whipworm.

Parasitic worms can enter the human body through undercooked meat like wild fish, pig meat and cow flesh, unfiltered water, mosquito attacks and contact with waste. This condition is more common in South Asia and Africa where personal hygiene is low. Worms can be treated at home by using antihelminitics such as diethylcarbamazine, mebendazole, benzimidazoles, praziquantel, ivermectin, and albendazole.
