Overview
Impetigo, sometimes referred to as school sores, is a usually not serious but highly contagious bacterial skin infection that can occur in people of any age, but most commonly affects children. The first signs of infection are red sores or blisters around the nose and mouth—but they can also appear on any other parts of the body. When the sores break open, they can ooze fluid, forming a tell-tale yellow-brown crust that can be extremely uncomfortable and visually unpleasant.
Causes
The two most common types of bacteria that cause impetigo are Staphylococcus aureus and Streptococcus pyogenes. These bacteria easily enter the skin through cuts, scrapes, or insect bites and can then spread from one person to another through touching, scratching, and even through sharing contaminated items such as towels or clothing.
Because certain conditions that create wounds that can increase your risk of getting impetigo, be extra careful if you have:
- Chickenpox (varicella)
- Herpes
- Head lice or scabies
- Burns
- Insect bites
- Haemorrhoids
Symptoms
The symptoms of impetigo may include:
- Small red sores that crust over quickly
- Large blisters that may take longer to burst and develop a yellow-brown crust
- Itching
- Swollen lymph nodes (lymph glands)
- Pain or discomfort in the infected area
Treatment
Treatment for impetigo depends on your symptoms, but getting back to having healthy skin may take over a week and involve:
- Topical antibiotics in the form of creams or ointments
- Oral antibiotics may be prescribed for more severe or widespread infections
- Hydrogen peroxide cream
