Study Notes
Impetigo Overview
- 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.
Causes and Risk Factors
- 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.
Symptoms
- 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.
Types of Impetigo
- 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.
Diagnosis and Treatment
- 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.
Essential Oils
- 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.
