Worms in humans are often, but not always, filarial worms. Filarial worms are parasitic worms in humans that require a human host to survive and complete the life cycle.

Loa Loa worms (also known as the “eye worm”) are classified as filarial worms, meaning they thrive in human tissue. Loiasis, often misspelled as “loaisis”, is the infestation of loa loa worms in humans.

While not fatal, human worms can be quite disgusting and they can wreak havoc on the human body from the skin to the intestines to the respiratory system. Human worms (parasites) are not uncommon either. In fact, it is believed that at any given time the human body may be infected with dozens of different types of parasites. Some are microscopic while others are visible to the naked eye. Some types of worms can be found most often in animals, for example, the bloodworm typically infects horses, and others may affect humans more often.
