Infected eczema occurs when a virus or bacteria gets into an open eczema wound. These infections worsen existing symptoms.
Eczema is more common in infants and children than in adults, although anyone can have the condition.
Sometimes, patches of eczema can become infected. This happens when a virus or bacteria gets into an open wound or cracked skin at the site of a rash. It is important for a doctor to treat infected eczema as soon as possible.
This article details what causes these infections, their signs and symptoms, and the available treatment options.
A variety of viruses, bacteria, and fungi can cause infected eczema. The following are some of the more common microbes responsible for causing infected eczema:
- Staphylococcus aureus (staph infection)

Some common complications of infected eczema include:
- prolonged eczema flare
- increased itchiness and blistering
In addition, severe eczema herpeticum can cause infections in the cornea of the eye, which may lead to blindness. If eczema herpeticum spreads to the internal organs, such as the brain, lungs, or liver, it can lead to organ failure. However, this is rare.
If a person has chronic eczema flares, they should speak with their doctor if they develop a fever, experience chills, have low energy, or show signs of infection, such as oozing blisters and excessive itchiness.
If a child or infant develops symptoms of infected eczema, their parent or caregiver should take them to a doctor immediately.

In cases of bacterial infections, a doctor may choose to use either an oral or topical antibiotic. They may also prescribe a steroid cream to reduce associated swelling and discoloration.
Fungal infections require antifungal creams or medication. Similarly, a steroid cream may help with a fungal-infected eczema rash. Some antifungal creams that may help with the infection are available over the counter.
Some people or caregivers may want to supplement medication with natural alternatives to treat or prevent infections.
People seeking natural remedies for infected eczema may choose to try the following:
- essential oils, such as evening primrose and tea tree
- herbal supplements for eczema flares
- natural soaps and creams with emollients

However, it is important to note that these natural remedies should not take the place of prescribed treatment. People should always follow the advice of medical professionals first.
A person can help prevent infected eczema by avoiding scratching and taking steps to reduce eczema flares. These steps include:
- Applying an emollient every day: Emollients are moisturizing products that help keep the skin intact and prevent it from drying out, easing eczema symptoms. Keeping the skin moisturized can help stop skin cracking and sores forming, reducing the risk of eczema becoming infected from outside sources. Learn more about emollients here.
- Practicing good hygiene: This is essential when applying creams and other topical ointments. Where possible, a person with eczema should remove cream from a tub or jar with a clean implement instead of their fingers to reduce the chance of bacteria entering the container.
- Taking care of flare-prone areas: For flares occurring in skin folds or areas that are naturally more moist, people should try to keep these areas dry and clean.
- Treating flares accordingly: A person should follow the recommended treatment plan to help manage and reduce any flares.
