What causes a rash in the internal groin area

My child has a rash - what can it be?

Many conditions are characterized by or associated with a rash on the skin. The assignment to a disease is often not easy. A rash associated with a fever indicates an infectious disease.

Contagious or non-contagious?

In order to be able to assign the rash to a disease and to answer the question of whether it is a contagious disease or not, the following information is important:

  • The age of the child
  • Do you have a fever or other symptoms?
  • Where did the rash first appear?
  • Is it an acute or chronic skin change?

age of the child

Infectious rashes rarely occur in the first six months of life because the infant is protected against many infectious diseases for a few months by the nest protection through the mother. Examples of rashes in the first half of life that are not contagious:

  • Newborn acne
  • Seborrheic dermatitis
  • Eczema

Contagious rashes with fever

The most common febrile infectious diseases are measles, rubella, scarlet fever, chickenpox, three-day fever, ringlet rubella and meningococcal disease, which show a typical pattern of distribution of the rash.

Concomitant skin rashes are less common in gastrointestinal infections, typhoid, infectious mononucleosis, toxoplasmosis or typhus.

The measlesexanthema is usually accompanied by a high fever, it has large patches, begins behind the ears and then affects the whole body. It only occurs after a few days when the child has already developed flu-like symptoms.

At rubella on the other hand, the child usually looks less sick, the rash begins on the face and is paler and smaller in spots.

The Scarlet feverexanthem leaves the face out, the child is seriously ill for about a day before a small, speckled, sandpaper-like, very dense-looking rash appears (especially in the groin), which can disappear after a few hours with milder progressions.

At chickenpox After a short phase with a general feeling of illness, many, severely itchy spots appear all over the body, which turn into small blisters after a short time. Often all stages of chickenpox occur side by side, the vesicles are infectious and easily burst.

Against that Three-day fever a lighter disease, the rash affects the body more than the face and disappears quickly.

The disease Ringlet rubella owes its name to the garland-shaped rash that often begins on the face and then spreads over the body. It can last for over a week.

The range of Meningococci The disease ranges from mild courses with spontaneous healing to a highly acute outbreak which, despite treatment, leads to death within a few hours. Clouding of consciousness, punctiform skin bleeding and circulatory collapse are indications of a life-threatening course of the disease. Treatment with antibiotics as early as possible is crucial.

Contagious rashes without fever

Lichen (Impetigo contagiosa) is caused by bacteria that are also part of the normal skin flora. In most cases, locally crusted vesicles form in the mouth area, which can fuse together.

Herpes Simplex and Herpangina are viral diseases that preferentially affect the lips and oral mucosa, where they lead to the formation of blisters.

scabies (Scabies) is caused by the scabies mite. Their secretions (feces and eggs) produce vesicles, pustules, wheals and, as secondary lesions, crusts, scratches and boils. It mainly affects skin folds. The neck and head can also be affected in small children.

The Hand, foot and mouth disease is a highly contagious, viral, usually harmless infectious disease that occurs primarily in the summer months. The result is a symmetrical rash with blistering on the hands, feet and an enanthem of the oral mucosa, which manifests itself as short-lived blisters in the oral cavity, especially in the area of ​​the tongue, palate and cheek mucosa. The changes in the hands and feet usually occur at the same time or only a short time later.

Non-contagious rashes with no fever

 

  • Hives (urticaria)
  • Allergies
  • Drug-induced skin rash
  • sunburn
  • Heat rash (miliaria)
  • Rose lichen (Pityriasis rosea)

The Hives is characterized by wheals and can be triggered by a wide variety of internal and external stimuli. Allergies, physical stimuli of the skin from heat, cold, light, pressure or water, as well as psychological stress can trigger urticaria. Often the trigger cannot be determined with certainty. The wheals usually go away on their own, usually just as quickly as they appeared. In the case of persistence, antihistamines relieve the symptoms, but this treatment only suppresses the symptoms.

The clinical picture one medicinal The rash that is triggered can be varied and occur after ingestion or topical application of drugs. The most important measure is the immediate discontinuation of the respective drug.

The causes of the Rose lichen are so far unknown. First, the reddish, about one centimeter large, with frilled scallops, so-called primary medallion, forms on the trunk of the body. After about one to two weeks, more foci will spread over the body. Treatment is usually not necessary and the disease will go away on its own.

What can be done about the rash?

Viral infectious diseases such as measles, rubella, chickenpox, three-day fever or rubella can only be treated symptomatically, whereby in addition to measures to lower the fever and adequate fluid intake, extensive isolation of the sick person is particularly advisable so that the highly contagious disease is not passed on to others.

Bacterial diseases such as scarlet fever or lichen planus must be treated with antibiotics, as scarlet fever can otherwise lead to late complications such as changes in the heart valves, and infections of the eyes or sinuses with lichen planus.

What prevention is there?

 

There are effective vaccinations against viral infectious diseases that are recommended as part of preventive medical check-ups. There is also a possible vaccination against meningococcal disease (bacterial infection).

In the case of allergies, the most important therapeutic and preventive measure is the consistent avoidance of the known allergen - whether diapers, certain types of fruit or medication: Avoid contact with the allergen.

When does my child have to see a doctor?

If you are not sure what type of rash it is and what to do about it, then definitely seek medical advice. In any case, you should contact your doctor immediately if you notice any bleeding into your skin.

You can distinguish bleeding from harmless reddening of the skin by pressing a glass surface (water glass) on the reddened area. Reddening of the skin disappears for a short time as a result of the pressure. The hemorrhage remains visible.

When does my child have to go to the hospital?

Inpatient treatment is urgently required, especially in the case of serious illnesses, such as meningococcal disease or a pronounced herpes infection in neurodermatitis. Meningococcal disease must be treated immediately with intensive medical treatment because life is threatened.
