What causes pustular rash

Impetigo is a relatively common skin disease. It is caused by excessive secretion of skin oil, which causes a lot of bacteria and garbage to accumulate on the surface of the skin. If the skin's resistance is relatively low or the skin is damaged, impetigo will occur. When this happens, you should go to the hospital for examination and treatment in time to avoid delaying the disease and making the situation worse.

Symptoms of impetigo

1. Simple pustulosis: It mostly occurs in skin folds, with a diameter of about 2-3 mm. The pus scars are slightly higher than the surrounding skin and have a slightly red base. Most of them occur within 1 week after birth.

2. Bullous: The pustules are relatively large (such as the size of peas or apricots), and contain transparent or slightly turbid liquid. They will burst when they swell to a certain extent. After the pustules burst, the area will feel like a burn. In patients with mild illness, the body temperature is normal or slightly higher, and it takes 1-2 weeks to heal.

Classification of herpes simplex

1. Bullous impetigo

Bullous impetigo is caused by Staphylococcus aureus and begins as millet-sized blisters that quickly enlarge to the size of a peanut or larger. At first, the contents of the blister are clear. After about one day, the blister fluid becomes turbid, and the pus sinks to the bottom of the blister. The superficial fluid remains clear, forming a crescent-shaped pus accumulation phenomenon, which is one of the characteristics of this type.

After the blister breaks, it becomes an erosive surface with pus scab on it. New blisters may develop around it. Skin lesions often occur on exposed parts of the body such as the face and limbs. The pathological changes are pustules under the stratum corneum of the epidermis, in which many neutrophils can be seen.

2. Impetigo

Impetigo is caused by hemolytic streptococci or a mixed infection of hemolytic streptococci and Staphylococcus aureus.

Blisters occur on the basis of erythema and quickly turn into pustules. The blisters are easy to break and form dense yellow thick scabs, which continue to expand around. It often occurs on the face, around the mouth, around the nostrils, and exposed parts of the limbs. Pathological changes are the same as those of the bullous type. This type may be accompanied by acute glomerulonephritis. Neonatal impetigo belongs to this type.

Treatment of impetigo

1. Prevent infection: Wash your hands thoroughly before and after contact with the patient, and soak your hands for 1-2 minutes and wash them thoroughly.

2. There are many small pus scars at the beginning. After piercing them, follow the doctor's instructions and soak the patient in specific medicine for 3-5 minutes. It will heal in 3-5 days.

3. Systemic medication: Use antibiotics, administered intravenously.

4. Enhance resistance: If necessary, a small amount of blood or plasma can be transfused to increase resistance.

5. Prevention: Patients should take a bath and change underwear every day.
