Is Eczema Contagious? What to Know

“Eczema is in no way contagious,” says Susan Massick, MD, a professor of dermatology at the Ohio State University in Columbus and a fellow of the American Academy of Dermatology. “You will not pass it along to someone if they touch your skin, nor will you develop eczema by being in contact with someone who has eczema.”
Here’s what to know about the genetic connection with eczema, as well as other risk factors for developing this common skin condition.
Eczema Isn’t Contagious, but It Can Be Hereditary
“When there are mutations in this gene, the skin is less able to retain water and becomes more susceptible to allergens, irritants, and pollutants,” says Peter Lio, MD, a clinical assistant professor of dermatology and pediatrics at Northwestern University’s Feinberg School of Medicine and a National Eczema Association board member. “However, this does not explain the majority of eczema cases out there.”

Other Potential Causes of Eczema
“Eczema is multifactorial, where your genetics, your own immune system, and both external and internal triggers can initiate a flare,” says Dr. Massick.
- Contact with allergens, such as perfumes, soaps, cosmetics, wool, and certain metals
- Temperature extremes
- Stress, both physical and mental
- Smoke or air pollutants
A dermatologist can help you manage and ease your eczema symptoms by recommending a personalized skin-care routine, says Massick.
