Wondering if that new rash is impetigo? Seeing clear pictures is often the first step to getting answers. This common and highly contagious skin infection, caused by bacteria like Staphylococcus or Streptococcus, has a distinct appearance that can be easily confused with other conditions. Getting familiar with its key visual signs helps you know when it’s time to seek a professional diagnosis.
Impetigo primarily presents in two forms. The most common is non-bullous impetigo, which starts as small red sores, typically around the nose and mouth, that quickly burst and leave behind signature golden or "honey-colored" crusts. The other type, bullous impetigo, involves larger, fluid-filled blisters (bullae) that appear on the trunk, arms, or legs; these blisters are less likely to rupture but the skin around them may be itchy. Key visual identifiers include:
- Red pimple-like sores that rupture easily.
- Pus-filled blisters (pustules) and subsequent yellowish-brown crusts.
- Spreading rash due to scratching or touching.
- Swollen lymph nodes near the affected area.
Frequently Asked Questions
Q: Is impetigo contagious?
A: Yes, impetigo is very contagious. It spreads easily through direct skin-to-skin contact with the sores or by touching contaminated items like towels, bedding, or toys.
Q: What causes the honey-colored crusts in impetigo?
A: The hallmark crusts are formed from dried pus and fluid that ooze from the ruptured sores. This is a classic sign of non-bullous impetigo.
Q: When should I see a doctor for suspected impetigo?
A: You should see a doctor as soon as you suspect impetigo. A proper diagnosis is crucial, and prescription antibiotic ointments or oral medications are typically needed to clear the infection and prevent its spread.
