Although intertrigo is not always a skin infection, bacteria, fungus and yeast can be a cause or contributing factor. Intertrigo is characterized by irritated, tenderness and redness in in skin folds including the inner thighs, underarms, groin, the folds under breasts in women and under the abdomen in obese people. The skin often looks raw and may ooze or itch.

Treatment of intertrigo focuses on keeping the affected area clean and dry. After bathing, patients should allow the skin folds to dry—using a hair drier can be helpful. Anti-fungal powders can help absorb moisture and inhibit the growth of fungus and yeast. +Additionally, steroidal or anti-fungal or anti-yeast creams, topical or oral antibiotics may be used (depending on the cause of the infection).
