Impetigo is skin infection. It produces blisters sores on the face and hands. It is caused by bacterial infection and distinguished by crusting skin lesions. Impetigo normally visible on the face and especially around a child’s nose and mouth. Other skin disorders may follow it. The skin usually has many types of bacteria on it, but undamaged skin is an effective barrier which keeps bacteria from entering and growing within the body. When there is a cut in the skin, bacteria can reside in the body and grow there, causing inflammation and infection. Cuts in the skin may occur with insect bites, animal bites, or human bites, or other injury or other accidents to the skin. Impetigo may happen on skin where there is no visible break.

The two important types of bacteria that causes impetigo are streptococcal and staphylococcal organisms. It mainly occurs due to bacteria that enters the skin through breaks or insect bites, it can also develop in skin that’s perfectly healthy. Impetigo may follow a current upper respiratory invasion such as a cold or other viral infection. After infection, new blisters may be seen on the patient with no visible break in the skin. However, during some close examination, these blisters will demonstrate some underlying physical damage.

Impetigo is an infection caused by group. A beta-hemolytic streptococci (GABHS) or S aureus. Remnants of ruptured bullae are seen at the time of presentation. Break-up of the epidermis is due to an exotoxin produced by staphylococci, which is the pathologic organism present in cases of bullous impetigo. In lesions of this type, isolation of methicillin-resistant S aureus has been as high as 20%. The organisms are supposed to enter through ruptured skin and are transmitted through direct contact.

Causes of Impetigo

Impetigo that is caused by staphylococcus aureus triggers larger fluid-containing blisters that appear clear, then cloudy. These blisters are more likely to stay intact longer on the skin without bursting. Common causes of Impetigo
