What is impetigo?

Impetigo is a prevalent and highly contagious skin infection. While it is mostly observed in children, occasional cases may occur in adults, particularly if they have been exposed to infected children. The infection typically manifests as red sores that burst and form honey-colored scabs.

The most common site for impetigo is on the face, typically around the nose and mouth, but it can also develop on other parts of the body, particularly on the hands and feet.

 

What are the symptoms of impetigo?

Common symptoms include dime to quarter-sized blisters that burst quickly, revealing red, moist skin underneath. A golden-colored crust forms in the center of the spots and spreads to the edges. These oozing sores can be painful and are highly contagious. If left untreated, impetigo can progress to a more severe condition known as ecthyma, characterized by darker-colored pus-filled bumps.

 

What causes impetigo?

Most cases are caused by the bacteria Staphylococcus aureus, while group A Streptococcus bacteria can also be a contributing factor. Due to its high contagion, impetigo can result from various direct causes, including age (most commonly found in children aged 2-5), sports involving skin-to-skin contact, warm weather, broken skin, crowded conditions, and direct contact with infected items.

 

How is impetigo treated?

Typically, impetigo treatment involves applying an antibiotic cream or ointment directly onto the sores. In cases with numerous sores, oral antibiotics may be recommended. Completing the full course of antibiotics is crucial, even if the blisters disappear, to prevent the infection’s return. Soaking the area or using a wet compress may be necessary to facilitate the antibiotic’s penetration.

If sores persist after antibiotic treatment, the doctor may conduct lab tests on the liquid inside the sores to identify the most effective antibiotics.

 

How long does impetigo last?

Untreated, impetigo may resolve in two to three weeks. Seeking treatment is recommended to prevent its spread. With treatment, impetigo can clear up in 7-10 days.

 

What is the difference between impetigo and shingles?

The primary distinction is that shingles is a viral infection, while impetigo is bacterial. Shingles can be painful, with a blistering rash typically around the stomach, caused by the same virus as chickenpox. Impetigo, though highly contagious, is less painful, with sores usually around the nose and mouth but potentially spreading to other areas like hands, feet, underarms, and groin.
