What is impetigo

First of all, pustules, also known as "infectious pustulosis", commonly known as "yellow water sores", is a common superficial skin infectious disease transmitted through contact, characterized by blisters, pustules, easy to break and form purulent scab. According to the different clinical manifestations, it can be divided into bullous and non bullous pustules. At the same time, it is also a disease that can cause serious damage to our skin. After getting the disease, timely treatment should be carried out at the early stage of the disease.

Secondly, non bullous pustules are often caused by Staphylococcus aureus and occasionally by group A beta hemolytic streptococcus. Bacteria adhere to, invade and cause infection after minor skin trauma. Bullous pustulosis is caused by Staphylococcus aureus, which can occur in the whole skin. The bacteria can produce and release exfoliative toxin. Exfoliative toxin combines with desmoglein-1 on the cell surface, resulting in the loss of adhesion between epidermal cells, cell lysis and bullous formation.

Finally, the disease is prevalent in summer and autumn, and is more common in children aged 2-7. The clinical manifestations of the two types are as follows: 1. Bullous pustules are common on the face, limbs and other exposed parts. One of the characteristics of this type of pemphigus is that the blister increases rapidly after 1-2 days, the blister fluid changes from clear to turbid, and the pus is deposited at the bottom of the blister, presenting as a meniscus shaped empyema. The wall of the blister is thin and loose, the erosion surface is exposed after the blister is broken, and yellow purulent scab is formed after the blister is dried. Sometimes in the scab around the new blisters, arranged in a ring, known as ring pustules. Patients with pruritus, generally no systemic symptoms. 2. Non bullous pustules usually occur on the face, around the mouth, around the nostrils, auricles and exposed parts of limbs. On the basis of erythema, thin-walled blisters appeared and quickly turned into pustules with obvious red halo around. After the pustule is broken, the pus dries and forms a thick honey yellow scab. The scab expands all around and can fuse with each other. Conscious pruritus, often due to scratch the bacteria inoculated to other parts, new rash. Scab about a week to fall off, healed, leaving no scar. Severe patients can be complicated with lymphadenitis, fever, etc.
