Impetigo

Impetigo is caused by bacteria, most commonly Staphylococcus aureus or Streptococcus pyogenes. These bacteria can enter the skin through small cuts, insect bites, or other breaks in the surface. Poor hygiene or close contact with someone who has impetigo can increase the risk of catching it.

The common symptoms include red sores that quickly burst and form honey-coloured crusts, itching, and mild discomfort. The infection can spread rapidly through scratching or touching the affected area. In some cases, small blisters may appear, which can ooze before crusting over.

Impetigo is typically treated with antibiotic creams or tablets prescribed by a healthcare professional. Mild cases can be managed with topical treatments like Fusidic Acid Cream, while more severe or widespread infections may need oral antibiotics such as Flucloxacillin or Clarithromycin. Treatment helps clear the infection and reduce the risk of spreading it to others.

With proper treatment, impetigo usually starts to improve within a few days and fully clears within 7 to 10 days. It’s important to complete the full course of antibiotics even if the skin looks better sooner. Healing can take longer if the infection is left untreated or if it spreads to new areas.

Impetigo remains contagious until the sores have completely crusted over or 48 hours after starting antibiotic treatment. During this time, it’s best to avoid close contact with others and not share towels, clothing, or bedding. Good hygiene and keeping the affected area clean can help prevent spreading the infection.

Impetigo is often triggered by breaks in the skin, such as insect bites, eczema, or cuts that allow bacteria to enter. Hot and humid weather can also make it easier for bacteria to grow on the skin. People with weakened immune systems or existing skin conditions are more prone to developing it.

Scratching or picking at the sores can make impetigo worse and spread the infection to other parts of the body. Using harsh soaps or not cleaning the affected area properly can also slow healing. It’s best to keep the skin clean, avoid touching the sores, and follow the prescribed treatment.

Impetigo can sometimes be confused with cold sores, eczema, or allergic skin rashes. The key difference is the distinctive honey-coloured crusts and the rapid spread typical of impetigo. If you’re unsure, a pharmacist or GP can help confirm the diagnosis and suggest appropriate treatment.

Mild cases of impetigo may eventually clear up without treatment, but this can take several weeks and increase the risk of spreading to others. Treatment with antibiotics helps speed up recovery and prevents complications. It’s always best to seek medical advice rather than waiting for it to resolve naturally.

If left untreated, impetigo can spread to other areas of the skin or to other people. In rare cases, it can lead to deeper skin infections or scarring. Prompt treatment helps stop the infection quickly and reduces the chance of complications.

Yes, impetigo can recur, especially if you come into contact with someone who’s infected or if the underlying cause – like eczema or a skin injury – returns. Maintaining good hygiene, washing hands regularly, and treating skin conditions early can help prevent it from coming back. Your doctor may recommend additional precautions if you have frequent recurrences.

Impetigo is usually mild and not dangerous, but it can cause discomfort and spread quickly. In very rare cases, untreated infections may lead to deeper skin problems or kidney inflammation. Prompt treatment and good hygiene make it unlikely to cause serious issues.

Because impetigo is highly contagious, it’s best to stay home until at least 48 hours after starting antibiotic treatment or until the sores have fully crusted over. This helps protect others from infection. Always follow your healthcare provider’s advice about when it’s safe to return.

Wash hands frequently, keep nails short, and avoid sharing towels or personal items. Cover sores lightly with a clean dressing to reduce contact. Regular cleaning of clothes and bedding also helps stop bacteria from spreading to others in your household.
