Impetigo is a common and highly contagious skin infection, especially among young children. In England and Wales, the weekly incidence in children aged 0 to 4 years has been estimated at 84 cases per 100,000. Though impetigo can affect people of any age, it is most frequently seen in early childhood. Knowing how long impetigo lasts, what triggers it, and how to treat it can help you or your child recover faster and avoid spreading it to others.
What is Impetigo, and How Does it Spread?
Impetigo is a bacterial skin infection caused by Staphylococcus aureus or Streptococcus pyogenes. It usually appears as red sores or blisters that burst and form a yellow-brown crust. These sores are often seen on exposed areas like the face, arms, or legs.
The condition spreads easily through direct skin contact or by touching contaminated objects such as towels, bedding, or clothing. Because of this, it is essential to maintain good hygiene and avoid sharing personal items when someone in the household has impetigo.
How Long Does Impetigo Last?
In most cases, mild impetigo heals within 7 to 10 days with proper treatment. Without any medication, it might take up to two to three weeks to clear completely.
Healing Time with Treatment
Topical antibiotic creams prescribed by pharmacists can help clear the infection more quickly—often within a week. Severe cases that cover larger areas or are not responding to creams may require oral antibiotics.
Factors That Affect Recovery
- Severity of infection: Larger or multiple sores may take longer to heal.
- Treatment response: Prompt use of antibiotics speeds up recovery.
- Skin type and immunity: People with weaker immune systems may need more time to recover.
- Hygiene practices: Regular handwashing and keeping the affected area clean can prevent reinfection.
Even after recovery, the affected skin may remain slightly red or lighter in colour for a short while but usually heals without scarring.
What Are the Common Symptoms of Impetigo?
The symptoms of impetigo can appear anywhere on the body, though it most often affects the face, especially around the nose and mouth.
Early Signs to Look For
- Small red spots that quickly turn into blisters
- Itchy or painful sores
- Oozing fluid that dries into a golden crust
- Mild swelling around the affected area
Impetigo on the Face
When impetigo appears on the face, it can cause discomfort and self-consciousness. Keeping the area clean and avoiding scratching is vital to prevent spreading it to other parts of the body or other people.
When to Seek Help
If the infection spreads rapidly, causes fever, or doesn’t improve within a few days of using a pharmacy treatment, speak with one of our pharmacists. They can advise if further medical attention is required.
What Causes Impetigo, and Who is Most at Risk?
Impetigo is caused when bacteria enter the skin through minor cuts, insect bites, or other skin conditions like eczema. It is particularly common among:
- Children aged 2 to 5 years
- People in close contact with someone infected
- Individuals with weakened immune systems
- Those who play contact sports or use shared facilities like gyms
Good hygiene is the best prevention method. Washing hands frequently, using separate towels, and cleaning minor cuts properly can greatly reduce the risk.
What is the Best Treatment for Impetigo?
Treatment for impetigo depends on how severe the infection is.
Mild Impetigo
- Topical antibiotic cream: Applied directly to the affected area for around 7 days.
- Gentle washing: Clean the skin with warm water and mild soap before applying the cream.
Moderate to Severe Impetigo
- Oral antibiotics: Recommended if the infection is widespread or doesn’t respond to creams.
- Avoid scratching: Helps prevent bacteria from spreading to other parts of the body.
Additional Care Tips
- Wash clothes, bedding, and towels in hot water daily.
- Avoid close contact with others until the sores have healed.
- Keep fingernails short to prevent bacteria build-up.

FAQs on Impetigo
1. Is impetigo contagious, and how can I stop it from spreading?
Yes, impetigo is highly contagious. It spreads through skin contact or by touching contaminated items such as towels, bedding, or toys. To stop it spreading, wash your hands often, keep sores covered with clean dressings, avoid scratching, and use separate towels and flannels until the infection has completely healed.
2. Can impetigo heal without treatment?
Mild impetigo can sometimes clear on its own within two to three weeks, but using antibiotic cream prescribed by a pharmacist helps it heal faster and prevents spreading. Without treatment, the infection may linger longer or worsen, especially if it spreads to other parts of the body.
3. How can I tell if my impetigo is getting worse?
If your sores become larger, more painful, or start oozing heavily, or if you notice redness spreading beyond the blisters, the infection may be worsening. Other warning signs include fever, swollen glands, or new sores appearing elsewhere. Contact one of our pharmacists if you notice any of these symptoms.
4. Can I go to work or school with impetigo?
It’s best to stay at home until the sores have fully healed or for at least 48 hours after starting antibiotic treatment, whichever comes first. This helps prevent passing the infection to others. Children should avoid nursery or school during this time, and adults should avoid close physical contact at work.
5. What can I do to prevent impetigo from coming back?
To prevent impetigo from returning, practise good hygiene — wash hands often, clean minor cuts promptly, and keep fingernails short. Wash clothing, towels, and bedding regularly, and avoid sharing them. Treating skin conditions such as eczema or insect bites early also helps reduce your risk.
6. What is the best way to treat impetigo on the face?
Use a topical antibiotic cream as directed by your pharmacist, keeping the area clean and dry. Avoid touching or picking at the sores to prevent spreading the bacteria. If the infection covers a large area or doesn’t improve after a few days, consult our pharmacist for further advice on oral treatment options.
