Well thats the answer...

Impetigo, a contagious skin infection that usually produces blisters or sores on the face and hands, is one of the most common skin infections among kids.

It is generally caused by one of two bacteria: group A streptococcus or staphylococcus aureus. Impetigo usually affects preschool and school-age children, especially in the summer months. A child may be more likely 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.

Good hygiene can help prevent impetigo, which often develops when there is a sore or a rash that has been scratched repetitively (for example, poison ivy can get infected and turn into impetigo). Impetigo is typically treated with antibiotics.

Signs and Symptoms
Impetigo may affect skin anywhere on the body but commonly occurs around the nose and mouth, hands, and forearms.

When impetigo is caused by group A streptococcus, it begins as tiny blisters. These blisters eventually burst and leave small wet patches of red skin that may weep fluid. Gradually, a tan or yellowish-brown crust covers the affected area, making it look like it has been coated with honey or brown sugar.

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.

Contagiousness
Impetigo may itch and can be spread by scratching. Kids can spread the infection by scratching it and then touching other parts of the body.

Impetigo is contagious and can spread to anyone who comes into contact with infected skin or other items, such as clothing, towels, and bed linens, that have been touched by infected skin.
