Impetigo

Impetigo is a term which is part of various different infectious skin diseases. Impetigo basically affects school-age children, most often during the hot, humid summer months. While impetigo can obvious as a primary pyoderma of intact skin, it may occur as a secondary infection of preexisting skin disease or traumatized skin, which has been referred to as impetiginous dermatitis. It frequently begins on the face, especially around the corners of the mouth, the nose and back of the ears.

The organisms are believed to enter through damaged skin and are transmitted through direct contact. Futher to infection, new lesions may be seen on the patient with no manifest break in the skin. It is mainly caused by one of two bacteria: group A streptococcus or staphylococcus aureus. The infection is transmitted by direct contact with lesions or with nasal carriers. The incubation period is 1-3 days. Dried streptococci in the air are not contigious to intact skin. In adults, it may advance other skin disorders. Impetigo may follow a newest upper respiratory infection such as a cold or other viral infection.

Impetigo which is caused by staphylococcus aureus triggers larger fluid-containing blisters which appear clear, then cloudy. It tends to develop and spread. Impetigo is infectious. The infection is beared in the fluid which oozes from the blisters. Rarely, impetigo may form deeper skin ulcers. In impetigo contagiosa, the lesions starts with a single 2- to 4-mm erythematous macule which rapidly educes into a vesicle or a pustule. Impetigo is a common skin disease, documenting for 10% of skin diseases treated in pediatric clinics.

Peak prevalence occurs during summer and fall. It first seems as a small scratch or itchy patch of eczema - skin inflammation - on ostensively healthy skin. A small red, itchy spot rapidly develops into a blister having a yellow substance. People who suffer from cold sores have shown higher risk of affecting from impetigo. Impetigo may form up to 10 days after the skin becomes infected with GABS. Good hygiene may help prevent impetigo, that often arises when there is a sore or a rash that has been scratched reiteratively.

Causes of Impetigo

The common causes and risk factor's of Impetigo include the following:

• Impetigo is frequently caused by the same streptococci strains as those which cause strep throat.
• The infection may be caused by a combination of the 2 organisms.
• A child may be more prone to develop impetigo if the skin has already been irritated or injured by other skin problems, such as eczema, poison ivy, insect bites, or a skin allergy to soap or makeup.
• It can also be caused by Staphylococcus infection.
• Direct contact with lesions or with nasal carriers.
