Skin Infection: Impetigo
It is an infection of the skin and is contagious in nature. Children usually get this infection from injury to the skin, often from another skin condition, such as dermatitis, an inflammation of the skin.
It is caused by staphylococcus and streptococcus bacteria. It is more common in children than in adults.
Types of Impetigo
Non-bullous Impetigo: It is most common, it initially manifests as small red papules similar to insect bites. These lesions quickly evolved to small blisters and then to pustules than finally scab over with a honey-colored crust.
Bullous Impetigo: It is caused only by staph bacteria, it produces a toxin that reduces cell-to-cell stickiness causing separation between the top skin layer and the lower layer. This leads to the formation of a blister.
Red sores that quickly rupture and then form a yellowish-brown crust. Itching and soreness are generally mild.
No lab tests are required, it is generally diagnosed by looking at the distinctive sores.
It is treated with the antibiotic ointment or cream which is directly applied to the sores.
