Infections that cause rashes include fungal, bacterial, or viral infection.

Rashes lasting more than a few days that are unexplained should be evaluated by a doctor.
What are noninfectious, common rashes localized to a
particular anatomical area?

over-the-counter 1% hydrocortisone cream for a week or so prior to seeking medical attention.
Seborrheic dermatitis: Seborrheic dermatitis is the single most common rash affecting adults. It produces a red, scaling eruption that characteristically affects the scalp, forehead, brows, cheeks, and external ears.
Atopic dermatitis: Atopic dermatitis, often called eczema, is a common disorder of childhood which produces red, itchy, weeping rashes on the inner aspects of the elbows and in back of the knees as well as the cheeks, neck, wrists, and ankles. It is commonly found in patients who also have asthma and hay fever.
Contact dermatitis: Contact dermatitis is a rash that is brought on either by contact with a specific chemical to which the patient is uniquely allergic or with a substance that directly irritates the skin. Some chemicals are both irritants and allergens. This rash is also occasionally weepy and oozy and affects the parts of the skin which have come in direct contact with the offending substance. Common examples of contact dermatitis caused by allergy are poison ivy or poison oak (same chemical, different plant) and reactions to costume jewelry containing nickel.
Diaper rash: This is a common type of contact dermatitis that occurs in most infants who wear diapers when feces and urine are in contact with skin for too long.

Wedding ring rash is a fairly common skin rash that occurs under the band of a ring. Individuals with a history of sensitive skin, eczema, allergies, or atopic dermatitis are more prone to this type of rash. Wedding ring rash is most commonly caused by either an actual allergy to the nickel component of the ring itself or an irritation from the buildup of soap and/or debris under the ring.
