Skin Rash

Overview

What is a skin rash?

A skin rash occurs when skin becomes red, inflamed and bumpy. Some skin rashes are dry and itchy. Some are painful. Many things can bring on a skin rash, including viruses, bacteria, allergens and skin conditions like eczema. 

How common are skin rashes?

Almost everyone develops at least one skin rash during their lifetime. It’s extremely common to sometimes feel itchy or have red, bumpy skin for a little while.

Who might get a skin rash?

Everyone — from infants to senior citizens — can get skin rashes. Infants are prone to diaper rash and cradle cap. Children are prone to atopic dermatitis and catch rash-inducing viruses, such as fifth disease. And older kids or adults can develop contact dermatitis as skin becomes sensitive to allergens or irritants over time.

What are the types of skin rashes?

There are many different types of skin rashes, including:

• Contact Dermatitis: This form of dermatitis occurs when your body reacts to a substance that it doesn’t like. Lots of people are allergic to fragrances, preservatives, nickel (often found in costume jewelry) and poison ivy. Common irritants include soaps, detergents, chemicals and household cleaners.

• Eczema: Also called atopic dermatitis, eczema often develops in infancy and often gets better as a child grows. It tends to run in families (genetic). People who have asthma or allergies are more likely to have eczema, too.

• Hives: Also called urticaria, hives cause raised, red, itchy skin welts. You may get hives if you have an allergic reaction to airborne allergens or insect stings. Extreme temperature changes and certain bacterial infections can also bring on hives.

• Psoriasis: This lifelong skin disorder causes a thick, scaly rash. The rash often forms on the elbows, knees, lower back, scalp and genitals. Psoriasis can be inherited.

• Viral: Skin rashes are a common symptom of many viral conditions, such as chickenpox, measles and molluscum contagiosum.
