Characteristics of the disease and types

Externally, bite-affected places resemble hives with bright red, small bruises. After 12 hours after contact with an insect, rashes can spread over the entire surface of the body. The extent of the damage depends on how many bites have been done. In this situation, the level of sensitivity and protective ability of a person to resist an aggressive substance, which is released by an insect plays an important role.

These harmful creatures seek a human victim at any time of the year, but most often this happens in the spring when their activity is at its maximum.

In the photo, tick-borne dermatitis is the highest activity of a parasitic insect:

It is enough to walk through the spring forest or to contact with the animals at such a time while staying in the village, and you can easily become prey for the mite.

It is worth noting that this insect is different from scabies ones because it does not make moves under the skin, it just feeds with blood. At the time of the bite, the tick releases a specific substance that is allergic to humans.

There are the following sources of infection: industrial and domestic. The first ones are located at granaries, processing plants, zoos. The second inhabit houses, mainly the first and last floors.

Perhaps the main distinguishing feature is the fact that the mite dermatitis is an acquired type of the disease.

MD types correspond to the name of its causative agent:

  • Rat — caused by mites that feed on rat blood. Most likely, laboratory workers, sanitary-epidemiological stations, residents of houses inhabited by rats are exposed.
  • Mouse — ticks are on the surface of the skin of mice. The risk group is similar to the first type.
  • Shoe — mite lives in shoes.
  • Pseudo-scab — scabies mites, live in the plumage of pigeons or in the fur of domestic animals.
  • Grain itch — pot-bellied and straw mites, arranged on insect larvae. Agricultural workers are most often affected.
  • Bird and snake — employees of zoos, poultry farms, terrariums.

How to recognize mite dermatitis?

The main symptom is skin rash and severe itching. The most likely areas to be affected by parasitic insects are the legs, the groin area, and the arms from the inside.

Arisen red spots are clearly delineated, have a hemorrhagic peel, identical with lichen. Symmetry is not preserved, the rash prefers thinner skin in the groin area, elbow and knee bends, between the arms and the breastbone.

Intolerable itching causes a person to scratch the affected areas, which is fraught with the introduction of additional infection.

Each type of disease is somewhat different in its individual characteristics. For example, infection from a granary insect makes very itchy blisters up to 3 cm (1.1 inches) in diameter appear. External signs are similar to urticaria.

In the case of shoe dermatitis, symptoms similar to an allergic reaction. They can be observed on the feet and legs.

By the way, these parasites are so dangerous that you can get not only dermatitis, but also Q fever, and tick-borne rickettsiosis.

An experienced eye of a dermatologist will be able to consider the absence of moves that the scabies mite makes. In such case, there is only bite marks left. Against the background of inflamed skin, these bites are not easy to detect, but the absence of double traces gives a hint to exclude the scabies diagnosis.

No matter how similar the symptoms of various skin diseases are, however, when compared with MD, you should pay attention to the main difference. It consists in the fact that all types of skin ailments have a number of external and internal causes. And mite-borne has only external signs, as bites.

Signs of mite dermatitis in children

Symptoms in children are similar to adults, but they are carried much harder. Most often, the source of infection is a household one. It is very important to consult a doctor after the first complaint from the child because his unformed immune system is not able to resist the aggressive substance that got into the blood along with an insect bite.

The temperature of the little patient rises rapidly, he becomes moody, nervous, he is tormented by irrepressible itching.

The affected child must first be shown to a pediatrician who can refer him to a dermatologist. Doctors will conduct diagnostic procedures and offer a treatment course.

Diagnosis of mite dermatitis

The most important thing is to accurately recognize the skin disease in order to confirm the preliminary diagnosis. The difficulty lies in the similarity of symptoms, distinctive signs can be determined with a more detailed examination. It is important to differentiate mite dermatitis with scabies, in order to not prescribe a treatment that has no sense.

No matter how professional a dermatologist is, an external examination and patient interview should be supplemented with clinical analyzes:

  • Blood test.
  • Provocative tests.
  • Scarification allergy tests.

After receiving the full clinical picture, the doctor makes a decision and prescribes treatment.

Features of the MD treatment

The medical complex includes such aspects:

  1. Eradication of the infection source by neutralizing parasitic insects.
  2. Prohibition of further contact with objects associated with the presence of ticks.
  3. Taking antihistamine drugs.
  4. Immunotherapy.
  5. Acceptance of hypoallergenic drugs and compliance with the appropriate diet.

The therapy complex also includes a procedure that helps to remove insects from the body surface – a hot shower.

To provide external therapy remedies with antiparasitic properties can be appointed. For example, Wilkinson’s ointment and sulfuric, benzyl benzoate suspension.

In the case of the grain dermatitis soda or potassium permanganate, warm baths can be used.

To soothe severe itching, the doctor prescribes Prednisolone or similar drugs.

Antiallergic drugs, as well as immunomodulators and aniline dyes, reduce the reaction to stimuli.

Sometimes, it is only needed to remove the mite from the body surface for dermatitis to pass without a trace or treatment. This happens only in cases of strong immunity and powerful protective resources of the patient’s body. On this basis, it is worthwhile to once again see how important a healthy lifestyle and attentive attitude to your own body are.

Traditional medicine against MD

Homemade medicinal herbs are quite capable of eliminating the unpleasant symptoms of mite dermatitis. The main thing is not to forget to consult with your doctor in advance, in order to eliminate the errors in self-treatment.

Chamomile with Bidens

Irritated skin from a tick bite can be brought to a normal state with a decoction of two well-known antiseptic plants — chamomile and Bidens. It is added to baths to relieve the discomfort that causes endless itching.

Propolis oil

Mix the crushed and heated bee product with vegetable oil and lubricate the places affected by the mite. Such a mixture has to be stored in a dark container.

Miraculous pumpkin


The pulp and juice of this vegetable is an excellent material for compresses in the case of MD. It is enough to do the procedure 2-3 times and there will be no trace of redness and rash.

Possible complications

Despite the fact that sometimes a person copes with mite dermatitis himself after removing the pathogen from the skin surface, yet the danger of this disease cannot be underestimated. After all, the tick can bring you many types of infectious diseases, from Staphylococcus to typhus.

If you are not responsible enough to treat, do not fulfill the appointments, you can get not so pleasant consequences in the form of scars.

In addition, with a strong itch, a person involuntarily scratches the affected areas, thereby violating the integrity of the skin, opening the way for the entry of pathogens. Thus, having received a secondary infection, the consequences can be far from bright.

Preventive measures

It is quite possible to avoid MD. To do so it is only necessary to implement preventive recommendations:

  • Do not contact with animals that may be carriers of ticks.
  • Avoid areas of parasitic insects’ habitat.
  • Periodically disinfect your living quarters.
  • Destroy rodents in the nearby territory.
  • Treat pets and their litters with special anti-tick agents.
  • Follow personal hygiene requirements.
  • Take a hot shower regularly.
  • Agricultural workers should wash their hands and other exposed parts of the body with a soda solution.

As for children, there is a need for special prophylaxis in order to maximally protect them from the possible tick’s danger. Before the child comes into contact with pets, you need to make sure that there are no harmful insects on their wool.

It is worth remembering that no one has immunity to MD. The only difference is that the stronger the health, the easier is to eliminate the tick. There is no place for such internal factors as heredity, but to some extent, a genetic predisposition to allergies may play a role. In such a person, the mite dermatitis will be somewhat more difficult due to the more intense allergic reaction.
