You may be surprised to learn parasitic worms can feed on human blood. Although some people laugh at having worms in their bodies, it is possible. Parasite transmission often occurs throughout infancy due to increased exposure and poor sanitation. Water, soil, food, and direct human touch may spread to other species.

Parasitic Worms: A Brief Summary

Parasites are living organisms that feed on and reside inside other living organisms, such as your body. Contaminated food and drink, insect bites, and sexual contact are all ways for them to spread. Some parasitic diseases are treatable, while others are not.

Parasites can be as little as single-celled protozoa or as large as worms visible to the naked eye. Various parasitic illnesses exist in the United States. Giardia infections are spread via contaminated water sources. Toxoplasmosis, which is hazardous to pregnant women, can be applied by cats. Malaria, for example, is common in many places in the world.

It’s crucial to consume water that you know is safe while travelling. It is vital to take precautions. Vaccines to guard against parasite infections are not available. Parasite infestations can be treated with a variety of medications. Below are some of the common diseases that are caused by parasitic worms.

Common Diseases Caused by Parasitic Worms:

A. Ascariasis:

Ascariasis is a disease caused by roundworms. These parasitic worms live on your body as larvae or eggs before maturing into adult worms. Adult reproductive worms may reach lengths of over one foot (30 cm). The majority of persons who are sick have little or no symptoms. Conversely, a significant infestation might result in severe symptoms and problems.

B. Schistosomiasis:

Schistosomiasis, often known as bilharzia, is an infection caused by a parasitic worm. Although schistosomiasis-causing worms are not found in the United States, individuals worldwide are impacted. In terms of severity, this infection is second only to malaria as the most lethal parasitic disease.

C. Hookworm Disease:

Intestinal hookworm is a type of worm that resides in the intestines. The larvae of hookworms enter the body via the skin. When the eggs reach the intestines, they hatch. Hookworms have a hook-like characteristic on their heads that allows them to connect to the intestinal walls.

D. Pinworm Infection:

One of the most prevalent intestinal worm infections in individuals is pinworm infection. Pinworms are small worms with thin bodies. They’re white and about half an inch long. Enterobiasis and oxyuriasis are other names for pinworm infestations. Infections with pinworms may spread quickly. They are widespread in youngsters aged 5 to 10 and those who reside in institutions and have regular, intimate interactions with these individuals.

E. Trichuriasis:

Trichuriasis, often known as whipworm infection, is a parasitic ailment of the large intestine caused by Trichuris trichiura. Because of its likeness to a whip, this parasite is colloquially known as a “whipworm.” Ingestion of polluted water or soil containing whipworm parasites might result in whipworm infection. Anyone who comes into contact with faeces harboring the whipworm parasite can become unwell. The sickness is widespread among youngsters. It is also more common in nations with hot, humid weather and communities with poor sanitation and hygiene.

F. Strongyloidiasis:

Strongyloidiasis is a parasitic worm illness caused by two different species of Strongyloides. S. stercoralis is the most frequent and clinically significant pathogenic species in humans. S fuelleborni is sometimes seen in Africa and Papua New Guinea.

G. Trichinosis:

Trichinosis, also known as trichinellosis, is a roundworm-borne sickness. To survive and proliferate, Trichinella parasitic roundworms need a host. These parasites may be found in bears, cougars, walruses, foxes, wild boars, and domestic pigs. After consuming the larval stage of the roundworm, you get ill.


Parasites are living entities that need a host, such as humans, to survive. Due to increasing exposure and inadequate sanitation, parasite transmission is standard throughout childhood. As a worm’s grasp becomes more potent, it becomes more difficult to expel it from the body.
