OVERVIEW

What is intertrigo?

Intertrigo is a rash that usually affects the folds of the skin, where the skin rubs together or where it is often moist. This rubbing can cause a breakdown in the top layers of the skin, causing inflammation and a rash. The breakdown of skin makes it easier for bacteria or fungus to develop in this area. It can make the rash worse.

Intertrigo is most common in people who are overweight or who have diabetes. People who have splints, braces or artificial limbs are also more likely to develop this rash.

SYMPTOMS

What are the symptoms of intertrigo?

Symptoms of intertrigo include a red or reddish-brown rash that can appear anywhere skin rubs together or traps wetness. This rash may burn or itch. The most common areas include:

• Between toes
• In the armpits
• In the groin area
• On the underside of the belly or breasts
• In the crease of the neck

Intertrigo can also affect the skin between the buttocks. The affected skin will often be very raw and may itch or ooze. In severe cases, intertrigo may cause a foul odor, and the skin may crack and bleed.

CAUSES & RISK FACTORS

This environment invites an overgrowth of yeast, fungus, and bacteria. Intertrigo is not contagious. You cannot catch it from or pass it to another person.

PREVENTION

TREATMENT

How is intertrigo treated?

For mild cases, your healthcare provider will tell you to keep the affected area of your skin dry and exposed to air. Your healthcare provider may also want to prescribe a topical steroid cream.
