Blisters on the palms and fingers look alarming, and many people wonder whether they can "catch" them or pass them on to others. This article gives a clear, evidence-based answer and explains why dyshidrotic eczema develops — and when it does make sense to see a doctor.
Dyshidrotic eczema (pompholyx) is not contagious. It cannot be passed on by touch or through ordinary physical contact — it is not an infection but an internal (endogenous) inflammatory skin reaction linked to genetics, atopy and triggers such as stress, sweating, nickel or irritants. In more severe forms the rash can spread across a person's own hands or feet, but it does not spread to other parts of the body or to other people. Because the blisters can resemble some contagious conditions, it is worth having them assessed by a doctor if you are unsure or there are signs of infection.
Is dyshidrotic eczema contagious?
No. Dyshidrotic eczema (pompholyx) is not contagious — you cannot catch it by touching another person's skin or through ordinary physical contact [1][2]. Although the blisters can look "infectious", this is not an infection but an internal (endogenous) inflammatory skin condition — that is, eczema, not a transmissible disease [3][4].
Why it isn't contagious — what causes it
The exact cause is unknown, but a combination of genetic predisposition and environmental factors is thought to be involved; the condition is often linked to atopy and runs in families [2][4]. Common triggers are stress, excessive sweating, contact with nickel or cobalt, and irritants — that is, external and internal factors, not a transmissible agent [3][4]. That is precisely why you can't "catch" it from anyone.
Can it "spread" over the body?
It's important to distinguish "contagious" from "spreading". In more severe forms the rash can spread from the fingers to the palms or soles, and in serious cases to the backs of the hands and feet. However, it does not spread to other parts of the body and does not pass to other people [2].
"Spreading" within your own hands and feet is not the same as being contagious. The eczema remains non-transmissible to others even with ordinary physical contact [2].
When it resembles a contagious condition
Dyshidrotic eczema can look similar to some contagious skin conditions — for example fungal ("athlete's foot") or bacterial infections. In itself, though, it is not an infection; it can even arise as a skin reaction (a so-called id reaction) to a fungal infection elsewhere on the body [3][4]. Because fluid-filled blisters can look like other conditions, it's advisable to have an unclear or new outbreak confirmed by a doctor [3][4].
Watch for secondary infection
The eczema itself stays non-contagious, but scratched, broken skin can develop a secondary bacterial infection (most often Staphylococcus aureus) [3][4]. Signs of infection — yellow fluid or pus, increasing redness, pain, swelling, crusting — are a reason to see a doctor [5].
How to care for sensitive skin
Even though it isn't contagious, dyshidrotic eczema can be troublesome. Alongside any medical treatment, gentle daily care helps: regular moisturising (emollients), avoiding irritants and harsh soaps, and protecting the hands [2]. EPIDERMA® offers cosmetic products for the daily care of sensitive skin — gentle, moisturising and dermatologically tested. They do not replace medical treatment but complement ordinary daily care.

Frequently asked questions
No. Dyshidrotic eczema is not passed on by touch or close contact — it is not contagious [1][2].
Fluid-filled blisters can resemble contagious conditions, such as fungal or bacterial infections. The eczema itself, however, is not an infection. If you're unsure, have the outbreak assessed by a doctor [3][4].
In more severe forms it can spread within the hands and feet, but not to other parts of the body or to other people [2].
When the outbreak doesn't improve, recurs, or shows signs of infection (pus, increasing pain, swelling, crusts), or when you're unsure of the diagnosis [3][5].
