Eczema is a common skin condition that can cause red, itchy, and inflamed patches on the skin. While eczema itself can be bothersome, it is possible for the affected skin to become infected. Knowing how to identify if eczema is infected is important because untreated infections can lead to more serious health problems. In this article, we will discuss the signs that your eczema might be infected, how infections develop, and what you can do about it.
Understanding Eczema and Its Symptoms
Eczema, also known as atopic dermatitis, is a chronic condition that makes the skin red, dry, and inflamed. It can occur anywhere on the body but is most commonly found on the face, arms, and legs. The exact cause of eczema is not fully understood, but it is believed to be related to a combination of genetic and environmental factors, including a compromised skin barrier and an overactive immune system.
Symptoms of eczema include:
- Itching (which can be intense)
- Dry, flaky skin
- Red or brownish-gray patches
- Thickened or leathery skin
- Small bumps that may leak fluid when scratched
These symptoms can flare up or improve over time, and eczema can be mild, moderate, or severe depending on the individual.
Why Eczema Can Get Infected
Eczema creates cracks or breaks in the skin, which can make it easier for bacteria, viruses, or fungi to enter the skin. The irritation caused by scratching can also further damage the skin and introduce germs. When an infection occurs, it can complicate the eczema and make it more difficult to treat.
Some people with eczema are more prone to skin infections because of their weakened skin barrier and immune system. Infected eczema is more likely to occur when the skin becomes moist from excessive scratching, sweating, or exposure to water, which can encourage bacteria to grow.
Signs Your Eczema May Be Infected
It’s important to know how to identify an infected eczema patch so that you can seek proper treatment. Here are some common signs that your eczema might be infected:
1. Increased Redness and Swelling
If the redness in the area of eczema becomes more intense or spreads, it could be a sign of infection. The skin may also become swollen, and the area may feel warm to the touch. This happens when the body’s immune system responds to the infection.
2. Pus or Fluid Drainage
One of the most noticeable signs of an infection is the appearance of pus or fluid coming from the eczema patches. This can occur when the skin is broken or scratched, allowing bacteria to enter and cause an infection. Pus is usually yellow or greenish in color, and if you notice this coming from your eczema, it is important to take action.
3. Pain and Tenderness
If your eczema feels painful or tender to the touch, it could be infected. Normally, eczema can cause itching, but if it becomes increasingly painful, it may be a sign of an underlying infection. You might also notice that the affected area feels sore or achy, and it may be difficult to move that part of your body without discomfort.
4. Crusty or Scabbed Over Skin
Infected eczema may start to form a crust or scab as a result of the skin’s attempt to heal. This can happen when there is an ongoing infection that is preventing the skin from healing properly. The crust can also trap bacteria and worsen the infection.
5. Fever
In some cases, an infected eczema patch can lead to a systemic infection, causing a fever. If you develop a fever along with your eczema symptoms, it is a strong indication that the eczema may be infected and that medical attention is needed.
6. Increased Itching or New Bumps
If the itching from eczema becomes significantly worse or if you notice new bumps appearing around the affected area, this could signal that an infection is present. The itching may become unbearable and may be accompanied by new fluid-filled blisters or pimples.
7. Change in Color
Infected eczema may also change in color, becoming darker or more red than usual. If the patches appear to be changing in color or if there are dark spots developing around the affected area, infection may be the cause.
8. Foul Odor
An infected eczema patch might emit a bad smell, which is usually a sign of bacterial growth. If you notice an unpleasant odor coming from the area, it is a clear indication that an infection has occurred.
Common Types of Infections That Affect Eczema
There are different types of infections that can occur with eczema, and they can affect the skin in different ways. Some of the most common types of infections include:
1. Bacterial Infections
The most common bacterial infection that occurs in eczema is caused by a type of bacteria called Staphylococcus aureus (often called “staph”). This bacteria can cause a skin infection known as impetigo, which is characterized by yellow, crusty sores. Staph bacteria can also infect the skin in more serious ways, leading to cellulitis (a deeper skin infection).
Another type of bacterial infection, caused by Streptococcus bacteria, can cause a condition called erysipelas, which involves bright red, swollen, and painful areas on the skin.
2. Viral Infections
Viral infections are also common in people with eczema, especially in cases of severe eczema. The most common viral infection in eczema patients is caused by the herpes simplex virus, leading to cold sores or a condition called eczema herpeticum. This is a serious infection that can cause fluid-filled blisters, fever, and general illness.
3. Fungal Infections
Fungal infections can also complicate eczema, especially when the skin becomes too moist. Fungi thrive in warm, damp areas of the body, so areas where eczema is located (such as the folds of the skin) may be prone to fungal infections. Ringworm is a common fungal infection that can appear in eczema patches, causing redness, itching, and scaling.
How to Prevent Infections in Eczema
Preventing infections in eczema is largely about taking good care of your skin and avoiding things that could irritate it further. Here are some tips to help prevent eczema from becoming infected:
Moisturize Regularly: Keeping your skin hydrated with emollients can help to restore the skin’s barrier, reducing the chance of infection.
Avoid Scratching: Scratching eczema increases the risk of breaking the skin, which can lead to infections. Use anti-itch creams or talk to your doctor about options for managing the itch.
Keep Skin Clean: Cleanse your skin with gentle, fragrance-free products to avoid introducing bacteria. Pat your skin dry gently after washing.
Wear Loose, Soft Clothing: Tight or rough clothing can irritate eczema and make the skin more susceptible to infection.
Use Steroid Creams or Topical Treatments: If prescribed by your doctor, use topical steroids or other medications to reduce inflammation and prevent flare-ups that can lead to infections.
Avoid Wet Conditions: Try to keep the skin dry, especially in areas where eczema is present. Excess moisture can create an environment where bacteria and fungi thrive.
What to Do If You Suspect an Infection
If you suspect your eczema has become infected, it is important to see a healthcare provider for proper treatment. Your doctor will examine the affected area and may take a sample of the pus or fluid to determine the cause of the infection. Treatment options may include:
Antibiotics: If the infection is bacterial, your doctor may prescribe topical or oral antibiotics.
Antiviral Medication: For viral infections, antiviral medications may be needed to treat conditions like eczema herpeticum.
Antifungal Creams: If a fungal infection is present, antifungal creams or oral medications may be recommended.
Stronger Steroid Creams: In some cases, stronger topical steroids may be needed to reduce inflammation and treat the infection.
It is important to follow your doctor’s instructions carefully and complete the entire course of treatment to avoid complications.
Conclusion
Knowing how to recognize the signs of an infected eczema patch is essential for preventing complications and ensuring that the infection is treated promptly. If you notice any of the symptoms mentioned above, it is important to seek medical attention to get the right treatment. By following proper skincare routines and taking steps to prevent infections, you can manage eczema more effectively and avoid unnecessary complications.
