Eczema is a skin condition that can cause red, itchy and dry skin. It is not caused by either a fungal or bacterial infection. Instead, it is a result of an overactive immune system. The immune system responds to an irritant or allergen by releasing chemicals that result in inflammation and redness on the skin.
Although it is not caused by an infection, eczema can increase the risk of infection in the skin. Bacterial and fungal infections can occur in areas of broken or cracked skin, which can occur due to eczema. People with eczema can also be more prone to more serious infections, such as staphylococcal scalded skin syndrome, which is a type of skin infection caused by a strain of bacteria called Staphylococcus aureus.
The best way to prevent infections from developing due to eczema is to manage it properly. This involves avoiding triggers that can cause flare-ups, using emollients to keep the skin moisturized, and using topical corticosteroids to reduce inflammation. It is also important to be aware of signs of infection, such as pain, pus, and fever, and to seek medical attention if these signs are present.
