Parasites under human skin

leg pain in the presence of subcutaneous parasites

If a person has subcutaneous parasites, it is important to consult a doctor in a timely manner and diagnose the problem. You are also required to choose a therapy regimen that will take into account the type of worms and their location. What parasites can live on human skin, what symptoms bother the patient at the same time, what kind of diagnostic measures will help determine the disease, and what medication treatment is performed when the diagnosis is confirmed?

Reasons for submission

Subcutaneous helminths, penetrating the human body, may not appear for years. When the worm matures, the infected person develops severe symptoms, which indicate that something is wrong with the body and medical attention is required. Worm larvae enter the host's body in the following ways:

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

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

Types of subcutaneous helminths, symptoms and location


Dranculosis - worms under the human skin that enter the body when they drink polluted water, live in places with warm climates. The parasites are located in the back, abdomen and legs, respectively in the subcutaneous layer. Adults reach sizes up to 150 cm, and pets can also be carriers. When larvae enter the human body, they migrate throughout the bloodstream, penetrating the internal organs and the subcutaneous layer. Adults reach sexual maturity after 12 months.

Due to the fact that skin parasites in a patient secrete their remains, the skin at the site of their localization swells, itches and when the tumor reaches a large size, it erupts, releasing new larvae. Leg larvae cause complications such as blood poisoning, joint problems and suffocation in the parasite habitats.


Dirofilaria - skin parasites in humans, which penetrate the host's body through the bite of insects, often mosquitoes. The main host of dirofilaria is a pet that is bitten by a mosquito, transferring the larvae with the bite to the human body. The incubation period lasts 2-3 years, while the infected person during this period does not bother with any symptoms. Dermophilia subcutaneous worm affects not only a person's skin, migrating larvae enter the sclera of the eye, leading to visual impairment, and in case of premature treatment, complete loss. Also, the worm can live in the scrotum and affect the patient's other genitals.

In the process of vital activity, intradermal parasites secrete toxic waste, resulting in itching and burning. As the parasite grows, so does the area of the skin lesion. To remove the worm, the affected area is resected by removing the dirofilaria.

Scabies mite

Scabies mites are parasites that live under the skin and can only be seen under a microscope. Placed in the subcutaneous layer, the mite develops vital activity, damaging the integrity of the dermis, due to which the patient worries about severe itching. By feeding on the human epithelium, the tick develops fully inside the patient's body and upon reaching puberty, lays eggs. Most often, the parasite is localized on the back, hands and fingers, on the soles of the feet, on the outer surface of the thigh, on the chest, in the armpits, on the genitals, on the scalp. Infection with a scabies mites is clearly visible visually, and if the disease is not treated, complications such as furunculosis, dermatitis, eczema develop.


The main carrier of the disease are infected insects that infect a person when bitten. When the larva enters the human body, symptoms of fever appear, which is accompanied by a rash on the skin. After that, the disease is not felt for several years. When larvae form, a person experiences symptoms such as a deterioration in general well-being, weakness, and fever. On the neck, torso and spine, rashes appear in the form of eczema, ulcers, warts and nodular growths. If the disease is not treated in a timely manner, the person suffers from vision, osteoarthritis concerns.


Schistosomiasis - subcutaneous worms that enter the human body after contact with contaminated water. Worms infect the patient's genitals, provoking itching, allergic rash, dermatitis. With schistosomiasis, the kidneys and liver are affected. Parasites in the testicles and scrotum cause inflammation, lumps and itching. It is important to diagnose the disease in time and start treatment with medication.


Cysticercosis is provoked by swine tapeworm larvae, which enter the human body when they drink contaminated water and meat from a sick animal. Helminths live under the skin, in the eyes, in the tissues of internal organs, muscles and even in the head. If the larvae are localized in the muscles and under the skin, there is pain and burning. The affected area under the skin, in which the helminth is located, increases in size, gradually becoming denser.


Subcutaneous parasites in humans are diagnosed directly in the office of an infectious disease doctor who examines the patient. The doctor evaluates the lesions, which determine the negligence of the disease. To confirm the diagnosis, the patient is referred for blood tests and scraping. For a more detailed diagnosis, instrumental methods are used that will help determine the location of the parasite and the number of adults in the body. When the diagnosis is confirmed, the doctor develops a treatment regimen.

Treatment of subcutaneous parasites in humans

Treatment of skin parasites is based on the use of a broad-spectrum anthelmintic agent. With inflammation, the use of antibiotics, a vasoconstrictor and antihistamines is indicated.

With dirofilariasis, when the worm is concentrated in one place and its movement is limited, an operation is prescribed, in which an incision is made in the affected part and the worms come out through the skin with the help of the doctor. Surgical removal is indicated for massive damage from large worms of internal organs, eye sclera and brain. You should not try to cure this type of helminthiasis yourself, using popular methods, as they are generally ineffective with abundant invasion and in some cases can harm the patient.


Since subcutaneous worms and mites enter the human body through the skin, after contact with an infected carrier, the first thing you need to do is follow the rules of hygiene: always wash your hands before eating, keep the room clean, change regularlyunderwear and bedding, do not let mosquitoes and other insects enter the apartment building.

If a person prefers to rest in places with tropical climate, it is worth taking care in advance of the quality of drinks, food and place of rest. If insects and animals that cause a parasitic disease live in the selected area, then it is worth consulting your doctor about safety rules that will help avoid infection.
