Impetigo Skin Infection

Study Notes

Impetigo is a bacterial infection that affects the skin, causing sores and blisters.
It can appear differently depending on the stage of infection and the affected body part.
Impetigo is a common contagious skin infection.

Bacteria like Staphylococcus aureus or Streptococcus pyogenes infect the outer layers of the skin (epidermis).
Anyone can get impetigo, but it most commonly affects children, especially those between 2–5 years old.
The infection often begins in minor cuts, insect bites, or a rash such as eczema - any place where the skin is broken.

The first symptoms of impetigo are discolored sores on the skin, often clustered around the nose and lips.
These sores quickly grow into blisters that may ooze, burst, and then form a yellowish crust.
The clusters of blisters may expand to cover more of the skin.
The sores can be itchy and occasionally painful.

There are three types of impetigo based on the bacteria that cause them and the sores that form:
- Nonbullous: causes patches of skin discoloration and sores that can break and crust over.
- Bullous: forms large, fluid-filled blisters that can burst open.
- Ecthyma: a more severe but less common form that affects deeper layers of the skin and can cause large, painful blisters that break into sores.

A doctor or healthcare professional can usually diagnose the infection by its appearance.
Antibiotics are the first line of treatment for impetigo.
The type of antibiotic depends on how widespread or severe the lesions are.
Topical antibiotic creams, gels, or ointments are preferred for small areas of skin, while oral antibiotics are used for severe or widespread cases.
Home remedies, such as keeping the area clean and covering it with bandages, can also help stop the infection from spreading.

Some people claim that certain essential oils, such as geranium oil, patchouli oil, and tea tree oil, can help remedy impetigo.
However, it's essential to speak with a doctor before using any essential oils, as they may not be safe for everyone and can cause side effects.
