General symptoms

Parasitic diseases attack an immunocompromised organism. There are signs common to all types of parasites:

  • allergy in the form of a rash, cough, urticaria;
  • a decrease in the production of immunoglobulin leads to a weakening of the immune system;
  • skin problems in the form of peeling, redness, itching;
  • pain in joints and muscles;
  • sleep disturbance;
  • lack of appetite;
  • grinding teeth while sleeping;
  • fatigue, weakness, irritability;
  • as a result of the colonization of the body with skin parasites in humans, the condition of the skin deteriorates;
  • flabbiness, painful color with many scars and abrasions from scratching is observed.

Any parasites in the human body lead to disruption of the functioning of internal organs, dysbiosis and anemia develop.

Emerging diseases from subcutaneous inhabitants

The most common parasitic skin diseases can be identified.

Filariasis in humans develops due to the fault of filamentous nematodes, which are carried by bloodsucking insects living in hot countries. They can live in the body and affect internal organs without symptoms for 7 years. The first characteristic symptom manifests itself in the form of allergies (urticaria), then the body temperature rises, and only after a few years dermatoses, ulcers, are observed. Heat in the body, drowsiness, weakness joins.

The scabies mite becomes the causative agent of scabies. It is a small parasite (only 0.2-0.4 mm). Penetrates into the deep layers of the skin, as they are softer, causing severe itching when moving. The life of an adult female in a human body lasts about 2 months - during this time she manages to lay many eggs. The incubation period lasts about 2 weeks.

Infection occurs through a contact-household way. The main symptoms of scabies are itchy rashes on the septa between the fingers. Itching is especially troubling during a night's sleep. During scratching, wounds, blisters and pustules are formed, which open, crusts form. Complications of the disease are boils, dermatitis, eczema.

Dracunculiasis is caused by round cyclops helminths. An adult can reach 120 cm. They enter the body together with raw contaminated water. After 2 weeks, they penetrate into the subcutaneous space. A favorite habitat is the area of ​​the legs. As a result of the further development of the larvae on the skin, swelling up to 7 cm, shaped like a cord, skin pustules can be observed. Upon contact with water, the bubble bursts, and other larvae spread.

As a result of infection with helminths, the joints suffer, which become inactive and become inflamed. Blood poisoning may occur. Surgical intervention is used to remove an adult from the body.


Ankylostomiasis. The parasites that cause this disease enter the body through wounds and abrasions on any part of the body, especially the lower extremities. In the affected area, severe itching sensations develop, hemoglobin decreases, symptoms of anemia appear.

Dirofilariasis is provoked by parasites such as dirofilariae. They can live not only under the skin, but also in various parts of the eye. The length of an adult reaches 35 cm. The carriers of these helminths are cats and dogs, and mosquitoes are considered carriers. By biting animals, they transfer the larvae to the human body. At the place where the larva stops, a seal develops, which becomes inflamed, reddens and causes itching. Treatment is carried out only by surgery.

Schistosomiasis. The causative agents of the disease are helminths that live in the rivers of hot countries. Infection occurs when water gets into the mouth while bathing. The main symptoms of the disease are dermatitis, rashes, which are accompanied by itching. There is a strong secretion of sweat, an enlarged liver and a violation of its functioning.

Cysticercosis is a disease caused by the larvae of pork tapeworms. Can enter the body together with food and raw water. Swelling, which does not cause pain, and becomes denser over the years, indicate the settlement of parasites under the skin.

Demodecosis disease is caused by demodex mites. In most cases, they live in the sebaceous glands of the face. Acne can fester, itch, and worsen the skin. Signs of this disease include eyelash loss.


The appearance of parasites living under the human skin provokes the development of serious diseases. After laying eggs, adults of many parasite species die, releasing toxic substances. As a result, intoxication joins.

Cutaneous types of parasites

Parasites can also live on human skin. Head lice disease is caused by lice bites. Depending on the type of habitat, three main types of skin lice can be distinguished.

  1. The head louse lays eggs in the hair. Symptoms include an itchy head, swollen lymph nodes.
  2. Body lice live in a person's clothes and only temporarily move to his skin in order to get nutrients with blood. The bite itself does not hurt the person, but after a while the place turns red and causes itching.
  3. Pubic view. It settles in the hairs of the pubic region, but can also move to other hair areas. In most cases, it is sexually transmitted.

Lice are transmitted through close contact with a sick person, as well as through personal hygiene items. External parasites include fleas, bedbugs and ticks.


Another common parasitic disease is mycosis. Caused by yeast-like fungi. You can get infected by contact with an infected person. The main symptoms of the disease are peeling, flaking of the nail plate, itching and redness of the toes or hands.

Diagnostics and treatment

A specialist on examination determines the area of ​​the lesion, examines the external manifestations, by which it is often possible to determine the type of parasite.

  1. Scraping from the affected areas of the skin is effective. But this method is carried out if there are wounds, pustules, blisters, peeling on the skin.
  2. Study of venous blood for the presence of antibodies produced by the body in response to helminths.
  3. The analysis of feces, the study of hair, nails, capillary blood can become informative.
  4. The patient needs to visit a dermatologist, infectious disease specialist, allergist and even a neurologist, since the nervous system is also affected.

If subcutaneous parasites have been found in humans, then they cannot be removed using traditional medicine recipes. They have a long exposure time, and the condition can deteriorate very quickly. Apply conservative or surgical intervention.

  1. Treatment begins with the use of antihistamines.
  2. Prescribe acaricidal agents - for example, Trichopol.
  3. Parasites under the skin of people are treated with antibiotic ointments and gels.
  4. In the case of a scabies mite, sulfuric or salicylic ointment helps. They treat the affected area every three days.
  5. Schistosomes are treated with surgery or chemotherapy.
  6. If the scabies mite is properly treated, then the disease goes away within a week. An emulsion of benzyl benzoate, which is used to treat the skin, does a good job. It is imperative to disinfect the room, wash and iron all bedding and clothes with an iron.

Even following the strict instructions of doctors, it is not always possible to quickly get rid of subcutaneous parasites. Sometimes it takes many months.

Preventive measures

The main reason for infection by any helminths is non-compliance with personal hygiene, eating unwashed food, direct contact with an infected person

You can reduce the risk of parasites entering the body by following some guidelines:

  • wash hands with soap and water as often as possible, especially before eating and after visiting public places;
  • you cannot put on the things of another person, as there may be maggots on the clothes;
  • it is not recommended to use someone else's cosmetics;
  • vegetables, fruits and berries must be thoroughly washed, sprinkling with boiling water;
  • wounds or abrasions need to be well treated, as a favorable environment is created for the habitat of skin worms;
  • vaccinations should not be neglected before traveling abroad.
