What a Rash Is

A rash is any change in the skin’s color, texture, or appearance, often caused by irritation, infection, allergies, or other health conditions.  Below are a few examples:

1. Contact dermatitis is a skin reaction that happens when your skin touches something irritating or causes an allergic reaction.

Common Signs

• Red, itchy skin
• Rash or small bumps
• Swelling or blisters in some cases
• Dry, cracked, or scaly patches

Tip: Avoiding the substance that caused it and keeping the area clean can help it heal. See a healthcare provider if the rash is severe, spreads, or shows signs of infection.

2. Eczema is a skin condition that makes your skin dry, itchy, and red. It can appear in patches and sometimes cause small bumps, cracking, or thickened skin.

Tips to manage it:

• Keep your skin moisturized
• Avoid scratching
• Identify and avoid triggers like harsh soaps, certain fabrics, or allergens
• See a healthcare provider if it gets infected or very uncomfortable

Key Points

• Rashes can be localized (one area) or widespread (over much of the body).
• Many rashes are mild and temporary, but some may indicate infections, allergic reactions, or other medical conditions.
• Seek care if the rash is severe, spreading quickly, painful, or accompanied by fever or other symptoms.
