Eczema is not contagious
No, you cannot catch eczema from another person. Eczema is not caused by a virus, bacteria, or fungus that spreads from skin to skin. It is a condition that develops when your skin barrier — the outer layer that holds in moisture and keeps out irritants — does not work the way it should.
You can be in close contact with someone who has eczema, share bedding, clothing, or towels, and still not develop the condition. Eczema runs in families because of inherited genes that affect how your skin functions, not because it spreads like a cold or infection.
Key Takeaways
- Eczema cannot be transmitted from one person to another through touch, shared items, or any other contact.
- The condition is caused by genetic factors and how your immune system reacts to irritants, not by contagious germs.
- If multiple family members have eczema, it is because they inherited similar genes, not because one person gave it to another.
- You can safely share personal items like towels and clothing with someone who has eczema without risk of catching it.
- Eczema flare-ups are triggered by things like dry air, stress, and irritating substances — not by exposure to another person's skin.
Why eczema runs in families
Eczema tends to appear in multiple family members because certain genes make your skin more prone to the condition. If one or both of your parents have eczema, you have a higher chance of developing it too. The same is true for other family members — siblings, cousins, or grandparents may all carry similar genetic traits.
These genes affect how your skin produces and maintains its protective barrier. They also influence how your immune system responds to irritants and allergens. When you inherit these traits, your skin behaves differently than someone without those genes — it loses moisture more easily and reacts more strongly to things that touch it.
This genetic link does not mean eczema is contagious. It means your body is wired in a way that makes eczema more likely to develop, especially when you encounter certain triggers like dry weather, stress, or harsh soaps.
What actually causes eczema flare-ups
Eczema flare-ups happen when your skin encounters something that irritates it or when your immune system overreacts to a trigger. Common triggers include dry air, harsh soaps and detergents, fragrances, stress, sweat, and certain fabrics like wool. None of these triggers are contagious — they are environmental or emotional factors that affect your skin.
When you have eczema, your skin barrier is weaker than it should be. This means irritants can get in more easily, and moisture escapes more quickly. Your immune system also tends to overreact to things that would not bother someone without eczema. This combination is what causes the itching, redness, and inflammation you experience during a flare-up.
Because flare-ups are triggered by things in your environment or your stress level — not by germs — there is no way to catch eczema from someone else's skin or their belongings.
Sharing items with someone who has eczema
It is completely safe to share towels, bedding, clothing, and other personal items with someone who has eczema. You will not develop eczema from using their towel or wearing their shirt. The condition cannot spread through fabric or any other object.
The only caution is if someone with eczema has an active skin infection on top of their eczema — for example, a bacterial infection from scratching. In that case, you would want to avoid direct contact with the infected area, just as you would with any skin infection. But eczema itself, without an infection, poses no risk.
If you live with someone who has eczema, you can share a bathroom, use the same soap dispenser, and hug them without any concern about catching the condition.
When eczema looks like it might be spreading
Sometimes people worry that eczema is contagious because multiple family members have it, or because it seems to appear suddenly in a household. This is almost always because of shared triggers, not because the condition is spreading from person to person.
For example, if a family moves to a dry climate or switches to a new laundry detergent, multiple family members with a genetic tendency toward eczema might all flare up at the same time. To an outside observer, it might look like one person's eczema gave it to everyone else. In reality, everyone was exposed to the same trigger, and their inherited skin traits made them all react.
Similarly, if a child develops eczema and a parent realizes they have had mild eczema symptoms for years, it can seem like the child caught it from the parent. What actually happened is that both inherited the same genes that make eczema likely.
Eczema with a secondary infection
Eczema itself is not contagious, but sometimes eczema leads to a skin infection that is contagious. When you scratch eczema intensely, you can break the skin and allow bacteria to enter. This can cause a secondary bacterial infection, usually from Staphylococcus aureus bacteria.
A bacterial skin infection can spread to other people through direct contact or shared items. If someone with eczema develops signs of infection — such as oozing, crusting, warmth, or pus — they should see a doctor. Until the infection is treated, it is wise to avoid sharing towels or having skin-to-skin contact with that person.
This is different from eczema itself being contagious. The infection is the contagious part, not the underlying eczema. Once the infection is treated with antibiotics or other medication, the risk of spread goes away.
What to do if you think you have caught something from someone with eczema
If you have developed a rash or skin symptoms after contact with someone who has eczema, it is almost certainly not because you caught eczema from them. More likely explanations include an allergic reaction to a product they use, irritation from a shared detergent or soap, or a coincidental skin condition that developed on its own.
The best step is to see a doctor or dermatologist, who can examine your skin and tell you what is actually causing your symptoms. They can rule out infections, identify allergies, and determine whether you have eczema or something else entirely.
If you do have eczema, learning that it is not contagious should be reassuring. You can live normally with family members, friends, and coworkers without worrying that you will pass it on or catch it from them.
Frequently Asked Questions
Can I catch eczema if I touch someone's eczema rash?
No. Eczema is not caused by anything that spreads through touch. You can safely touch someone's eczema rash without any risk of developing eczema yourself. The only exception is if they have a secondary bacterial infection on top of their eczema, in which case you would want to avoid direct contact with the infected area.
If my parent has eczema, will I definitely get it?
Not necessarily. Having a parent with eczema increases your risk because you may inherit genes that make eczema more likely, but it does not may provide you will develop it. Some people inherit the genes but never experience eczema symptoms. Others develop it only when they encounter certain triggers.
Can eczema spread from one part of my body to another?
Eczema itself does not spread from one area of your skin to another. However, if you scratch an eczema rash and then touch another part of your body, you can transfer bacteria or irritants that may trigger eczema in that new location. Keeping your nails short and resisting the urge to scratch can help prevent this.
Is it safe to share a bed with someone who has eczema?
Yes, it is completely safe. Eczema is not contagious, so sharing a bed, pillows, or blankets will not give you eczema. You may want to use gentle, fragrance-free detergent when washing shared bedding if you have sensitive skin, but this is for your own comfort, not because of any risk from the other person's eczema.
What should I do if I develop a rash after being around someone with eczema?
See a doctor to find out what is causing your rash. It is unlikely to be eczema caught from the other person. More common causes are an allergic reaction to a product, irritation from a shared soap or detergent, or an unrelated skin condition. A doctor can examine your skin and give you a clear answer.
