Cause #2: Bacteria

Bacterial infections, such as impetigo and erythrasma, can also cause itching in the groin area. Erythrasma is caused by bacteria known as Corynebacterium minutissimum while impetigo is caused by Staphylococcus bacteria. Erythrasma appears more often in obese people and those with diabetes. Impetigo is more common in children.

Erythrasma is more like jock itch because it usually occurs in areas where skin touches skin, such as the groin and under the breasts. While impetigo can affect the groin, it is more likely to occur in other areas, including the armpits, lips, face, and arms. To avoid spreading the infection, minimize touching other people and avoid sharing clothes. Since they are bacterial infections, erythrasma and impetigo are treated with antibiotics.
