How do I recognize the disease from the rash?
Skin rash is medically called an exanthem and on closer examination of the rash, one recognizes differences in spread, scaling and soreness - along with the accompanying circumstances such as fever, malady or contact with other people with an infectious disease, the wide range of diseases with rashes already restricted by the expert become.
- The Masernexanthem is usually accompanied by a high fever, it is large, starts behind the ears and then affects the whole body. It occurs only after a few days, when the child already has flu-like symptoms. When the rash fades, the upper layer of the skin dissolves with small scales.
- In rubella, however, the child is usually less ill, the rash begins on the face and is paler and spotty.
- The scarlet rash leaves the face, the child is seriously ill for about a day, before a small patchy, very tight-looking rash appears, which can disappear on lighter gradients even after a few hours.
- In chickenpox, after a brief period of general malaise, many very itchy patches appear all over the body, turning into small blisters after a short time. Often, all stages of chickenpox occur side by side, the blisters are infectious and burst easily. In contrast, the three-daytime fever is a lighter disease, the exanthem attacks more the body, less the face and disappears quickly.
- The disease Ringelröbel owes its name to the garland-shaped rash, which often begins in the face and then spreads over the body. It can persist for over a week. Impetigo is caused by bacteria, which are also part of the normal skin flora. It is usually in the mouth area locally encrusted bubbles that can merge together.
- Herpes simplex and herpangina are viral diseases that affect the lips and oral mucosa and lead to blistering. Allergies can lead to extremely different rashes. While in contact allergies (eg on diaper material or clothing) redness often occurs only on the body parts that also have contact with the triggering allergen, the rash may occur in food intolerances on the entire body or face. In addition to redness, blisters, small papules and scaling occur, the accompanying itching often leads to secondary inflammation of the damaged skin.
- Cradle cap (on the hairy scalp) and atopic dermatitis are often coupled with incompatibilities, but may also occur without allergenicity. The flaky, reddened skin is particularly sensitive and in need of care.
- The rashes of psoriasis and eczema differ in their localization - while psoriasis often occurs on the scalp and the extensor sides of the joints, eczema occurs more in the flexor folds.
- Porphyria and pemphigus are blistering chronic skin diseases that occur all over the body and require long-lasting therapy.
