Rashes can be caused by viruses and bacteria, medicines, heat, allergies, and many other things. Rashes often are only minor problems, but some can be serious and need medical treatment.

A skin rash can cause:

• redness
• spots on the skin
• scaly skin

• bumps
• blisters
• pimples

What Should I Do if My Child Has a Rash?

To ease discomfort from dry or irritated skin:

• Add a few cups of oatmeal to the bath.
• Use warm, not hot, water for baths and showers. Use mild, unscented soap or non-soap cleansers.
• Pat the skin dry (instead of rubbing) after a bath or shower.
• Moisturize skin well with non-fragranced ointment like petroleum jelly.
• Don't scrub or scratch the affected skin.
• Leave the rash exposed to the air as much as possible.

When Should I Call the Doctor About a Rash?

Call the doctor if your child has a rash and:

What Can Help Prevent Rashes?

Rashes can be hard to avoid. But to help prevent some types:

• Have kids avoid people with contagious skin rashes.
• For allergic rashes, try to avoid whatever caused the reaction. Ask the doctor if your child needs to carry emergency epinephrine.

• If your child gets eczema flare-ups, avoid harsh soaps and follow the doctor’s instructions for keeping your child’s skin well moisturized.
• Keep kids up to date on vaccines to avoid vaccine-preventable diseases that cause rashes.
