Is Acrodermatitis Enteropathica contagious?

Acrodermatitis enteropathica is absolutely not contagious and cannot be spread through touch, bodily fluids, or any form of social contact. It is a rare genetic disorder caused by an inability to properly absorb zinc from the diet, meaning there is zero risk to family members, caregivers, or friends when interacting with someone who has the condition.

What causes Acrodermatitis enteropathica?

Acrodermatitis enteropathica is an autosomal recessive genetic disorder caused by mutations in the SLC39A4 gene. This gene is responsible for creating a protein (ZIP4) that transports zinc across the intestinal wall. Because the body cannot absorb zinc efficiently, individuals develop a severe deficiency that leads to characteristic skin lesions and other systemic issues. It is a metabolic condition, not an infection.

Why is there confusion about contagion?

The confusion regarding Acrodermatitis enteropathica often stems from its outward presentation. Because the condition causes visible, often weeping, skin rashes—frequently appearing around the mouth, hands, feet, and diaper area—observers may mistakenly assume the lesions are infectious or fungal in nature. This stigma is entirely unfounded; Acrodermatitis enteropathica is strictly an internal metabolic dysfunction.

Are there environmental triggers for the condition?

While the primary cause is genetic, the symptoms of Acrodermatitis enteropathica are heavily influenced by nutritional intake. The following factors can exacerbate the clinical presentation:

• Breastfeeding vs. Formula: Symptoms often emerge shortly after weaning from breast milk, as human breast milk contains factors that enhance zinc absorption.


• Dietary Zinc Intake: Low dietary zinc levels will trigger or worsen the physical manifestations of the disease.


• Intestinal Health: Secondary issues that impair gut absorption can further complicate the management of Acrodermatitis enteropathica.

Next steps

• Consult a metabolic specialist or a pediatric dermatologist for ongoing management.


• Ensure regular monitoring of serum zinc and alkaline phosphatase levels.


• Connect with the 1 member of the Acrodermatitis enteropathica community on DiseaseMaps.org to share experiences and support.


• Educate family and school staff about the non-contagious nature of the disease to reduce social stigma.
