Parasites under human skin

foot pain in the presence of subcutaneous parasites

If a person has subcutaneous parasites, it is important to see a doctor in good time and diagnose the problem. In addition, a therapeutic system should be selected that takes into account the type and location of the worms. What parasites can live in human skin, what symptoms bother the patient at the same time, what diagnostic measures help diagnose the disease, and what medication is given to confirm the diagnosis?

Reasons for appearance

Subcutaneous helminths that penetrate the human body do not show up for years. When the worm develops, the infected person develops severe symptoms that indicate that something is wrong with the body and that medical help is needed. The larvae of the worm enter the host in the following ways:

  • through the bites of infected insects;
  • when they drink the water in which the larvae are present;
  • in contact with the skin of an infected person.

To determine what parasites have entered a person’s skin, you should contact a physician dealing with an infectious disease who will send the patient for research. After a series of diagnostic tests, the doctor identifies the type of worm and prescribes appropriate treatment. It is not recommended to try to remove the parasites under the skin yourself, as this can worsen the condition and cause life-threatening complications.

Types, symptoms and localization of subcutaneous helminth samples


Dranculosis - worms under the skin of the skin that enter the body while drinking dirty water live in countries with warm climates. The parasites are found on the back, abdomen, and legs, namely in the subcutaneous layer. Adults reach a size of 150 cm and pets can also be carriers. When larvae enter the human body, they migrate into the bloodstream, penetrating the internal organs and the subcutaneous layer. Adults reach sexual maturity after 12 months.

Due to the fact that the patient's skin parasites secrete their waste products, the skin at the site of localization swells, itches, and when the tumor reaches large size, it explodes, releasing new larvae. The larvae in the leg cause complications such as sepsis, joint problems, and pus in the parasite’s habitats.


Dirofilaria - human skin parasites that enter the host through insect bites, often mosquito bites. The primary host of dirofilaria is a domestic animal that is bitten by a mosquito and delivers the larvae into the human body along with the bite. The incubation period is 2-3 years, during which time the infected person is not disturbed by any symptoms. Dirofilaria subcutaneous worm not only affects the human skin, migrating larvae enter the sclera of the eye, damage vision, and complete loss if treated prematurely. In addition, the worm can live in the scrotum and affect the patient's other genitals.

During vital activity, intradermal parasites excrete toxic waste products that cause itching and burning. As the parasite grows, the area of the lesion on the skin also increases. To remove the worm, the affected area is removed by extracting the dirofilaria.

Group of mites

Scabies mites are parasites that live under the skin and are only visible under a microscope. Settling in the subcutaneous layer, the mite performs a vital activity that impairs the integrity of the dermis, causing the patient to fear severe itching. Feeding on the human epithelium, the tick fully develops in the patient’s body and lays eggs when puberty is reached. The parasite is most commonly located on the back, hands and fingers, soles of the feet, the outer surface of the thighs, chest, armpits, genitals, and scalp. The infection of the scabies mite is clearly visible, and if the disease is not treated, complications such as furunculosis, dermatitis, eczema develop.


The main carrier of the disease is infected insects, which infect humans when bitten. When the larvae enter the human body, feverish symptoms occur, accompanied by a rash. After that, the disease does not feel for several years. When larvae develop, a person experiences symptoms such as deterioration in general well-being, weakness, and an increase in temperature. Rashes appear on the neck, trunk and back in the form of eczema, ulcers, warts and nodules. If the disease is not treated in time, the person suffers from vision and arthrosis worries.


Schistosomiasis - subcutaneous worms that enter the human body in contact with contaminated water. The worms infect the patient's genitals, causing itching, allergic rashes, and dermatitis. Schistosomiasis affects the kidneys and liver. Parasites in the testicles and scrotum cause inflammation, lumps and itching. It is important to diagnose the disease in time and start taking medication.


Cysticercosis is caused by the larvae of the porcine tapeworm that enter the human body through the drinking of contaminated water and the meat of a sick animal. The helminths live under the skin, in the eyes, in the tissues of the internal organs, in the muscles and even in the head. If the larvae are located in the muscles and under the skin, there is pain and a burning sensation. The affected area under the skin in which the helminth is found grows in size and gradually becomes denser.


In humans, subcutaneous parasites are diagnosed directly in the office of a doctor dealing with infectious diseases, who examines the patient. The doctor will assess the lesions that determine the neglect of the disease. The patient is referred for blood testing and sampling to confirm the diagnosis. For a more detailed diagnosis, instrumental methods are used to help determine the location of parasites and the number of adults in the body. After confirming the diagnosis, the doctor will develop a treatment regimen.

Treatment of subcutaneous parasites in humans

The treatment of skin parasites is based on the use of a broad-spectrum anthelmintic. In case of inflammation, the use of antibiotics, vasoconstrictors and antihistamines is recommended.

In dirofilariasis, when the worm is concentrated in one place and its movement is restricted, surgery is prescribed in which an incision is made in the affected area and the worms come out through the skin with the help of a doctor. Surgical removal is recommended for severe damage to the internal organs caused by sclera of the eye and brain. Do not try to cure this type of helminthiasis yourself by folk methods, as they are usually ineffective in the event of abundant invasion and in some cases can harm the patient.


As subcutaneous worms and mites enter the human body through contact with the infected carrier, the first step is to follow hygiene rules: always wash your hands before eating, keep the room clean, change your underwear and bedding regularly, do not let it go, to allow mosquitoes and other insects to enter the residential building.

If you prefer to relax in countries with a tropical climate, it is worth taking care of the quality of drinks, food and the resting place in advance. If the selected area is home to insects and animals that cause parasitic disease, it is a good idea to consult your doctor about safety rules to help prevent infection.
