What to do on day one of impetigo

Impetigo often starts on irritated or broken skin as small red areas, blisters, or sores that ooze and develop a crust. It can enlarge or appear in more than one place through scratching and contact. Early appearance is not enough to confirm the diagnosis: eczema, insect bites, cold sores, and other infections can resemble it. Take a clear note of when the first spot appeared, where it is, and whether new areas are developing.

Wash hands, gently rinse the skin, and pat it dry. Do not squeeze or pick lesions. Cover them with a clean dressing if advised and keep nails short. Use separate towels and washcloths, avoid close skin contact, and clean items that touch the area. Do not use antibiotics left from a previous illness. A clinician may recommend [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) or a topical option after examining the skin.

Seek same-day advice for sores near the eye, rapidly spreading redness, severe pain, fever, unusual sleepiness, or difficulty drinking. Arrange assessment promptly for a newborn, a child who seems unwell, or anyone with reduced immune defenses. If the main feature is persistent [Crusting Skin](/symptoms/skin-crusting/), diagnosis still requires an examination.

Ask whether the appearance fits impetigo, how to clean and cover it, which contacts should be avoided, and what improvement to expect after treatment begins.
