Exploring 7 Common Parasites Found in Humans

Parasites are organisms that live on or within another organism (host) and rely on them for survival. In humans, parasites can cause a range of health problems, from mild discomfort to serious illnesses. Some common parasites found in humans include hookworms, flatworm blood fluke, scabies, tapeworms, pinworms, giardia, and toxoplasmosis.

These parasites can enter the human body through various means, such as ingestion of contaminated water or through insect bites. In this article, we will take a closer look at each of the parasites we mentioned. Fortunately, you can learn everything you need to know about parasites with a search online right now, which could help you spot early symptoms.

Hookworms

Hookworms are small, thin, and thread-like parasites that live in the small intestine of humans. They are usually transmitted through contaminated soil, where the larvae can penetrate the skin of the feet. Symptoms of hookworm infection include anemia, abdominal pain, diarrhea, and fatigue. Treatment typically involves medication to kill the worms and replenish the body’s iron supply.

Flatworm Blood Fluke

Flatworm blood fluke is a type of parasite that can cause schistosomiasis, a disease that affects millions of people worldwide. The parasite enters the human body through contact with contaminated water, such as in lakes and rivers. Symptoms of schistosomiasis include rash, abdominal pain, diarrhea, and blood in the urine. Treatment involves medication to kill the parasite.

Scabies

Scabies is a contagious skin condition caused by tiny mites that burrow into the skin. The mites lay eggs, which hatch and cause intense itching and a rash. Scabies is transmitted through skin-to-skin contact with an infected person. Treatment typically involves medication to kill the mites and their eggs, as well as washing all clothing and bedding in hot water.

Tapeworms

Tapeworms are long, flat parasites that can live in the human intestines. They are usually contracted through the consumption of contaminated meat, such as pork or beef. Symptoms of tapeworm infection include abdominal pain, nausea, diarrhea, and weight loss. Treatment involves medication to kill the worm and its eggs.

Pinworms

Pinworms are small, white worms that can live in the colon and rectum of humans. They are usually transmitted through contact with contaminated objects, such as bedding or clothing. Symptoms of pinworm infection include itching around the anus, especially at night. Treatment typically involves medication to kill the worms and their eggs.

Giardia

Giardia is a type of parasite that can cause diarrhea and other gastrointestinal symptoms in humans. It is typically contracted through the ingestion of contaminated food or water. Symptoms of giardiasis include diarrhea, abdominal pain, and bloating. Treatment involves medication to kill the parasite and alleviate symptoms.

Toxoplasmosis

Toxoplasmosis is a parasitic infection caused by the Toxoplasma gondii parasite. It is usually contracted through contact with infected cat feces or undercooked meat. Most people with toxoplasmosis have no symptoms, but it can be serious for pregnant women and people with weakened immune systems. Treatment involves medication to kill the parasite.

Talk To Your Doctor

Parasites can cause a range of health problems in humans. It is important to take steps to prevent parasitic infections, such as washing hands regularly, cooking meat thoroughly, and avoiding contact with contaminated water or soil. If you suspect that you have a parasitic infection, it is important to see a healthcare provider for diagnosis and treatment.
