Impetigo is a highly contagious bacterial skin infection most common among pre-school children. People who play close contact sports such as rugby, American football and wrestling are also susceptible,regardless of age. Impetigo is not as common in adults. The name derives from the Latin impetere It is also known as school sores.

Impetigo contagiosaThis common form of impetigo, also called nonbullous impetigo, most often begins as a red sore near the nose or mouth which soon breaksleaking pus or fluid, and forms a honey-colored scab followed bya red mark which heals without leaving a scar.Sores are not painful but may be itchy.LN in the affected area may be swollen, but fever is rare. Touching or scratching the sores may easily spread the infection to other parts of the body.[3]

Impetigo contagiosaThis common form of impetigo, also called nonbullous impetigo, most often begins as a red sore nearthe nose or mouth which soon breaks leaking pusor fluid, and forms a honey-colored scab followed bya red mark which heals without leaving a scar.Sores are not painful but may be itchy.LN in the affected area may be swollen, but fever is rare. Touching or scratching the sores may easily spread the infection to other parts of the body.

CausesIt is primarily caused by Staphylococcus aureus, and sometimes by Streptococcus pyogenes.TransmissionThe infection is spread by direct contact with lesions or with nasal carriers. The incubation period is 1–3 days. Dried streptococci in the air are not infectious to intact skin. Scratching may spread the lesions.DiagnosisImpetigo generally appears as honey-colored scabs formed from dried serum, and is often found on the arms, legs, or face.

TreatmentFor generations, the disease was treated with an application of the antiseptic gentian violet.Today, topical or oral antibiotics are usually prescribed.Mild cases may be treated with bactericidal ointment, more severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin or erytromycin.
