Impetigo, a contagious skin infection that usually produces blisters or sores on the face, neck, hands, and diaper area is one of the most common skin infections among children.
It is generally caused by one of two bacteria: staphylococcus aureus or group A streptococcus.
There are two types of impetigo:
bullous impetigo (large blisters) -nearly always caused by staphylococcus aureus
non-bullous impetigo (crusted) impetigo - the most common type usually caused by staphylococcus aureus but can also be caused by infection with group A streptococcus
Typical presentation in impetigo
* Tender, red rash
* Honey-colored crusts
* Poorly healing wound
Bullous impetigo presents with small or large, superficial, fragile bullae.
Non-bullous 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.
Mild cases may be treated with bactericidal ointment.
More severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin or erythromycin.
