Usually, rashes aren't harmful or dangerous.</p> <h4>Causes</h4> <p>Many things can cause rashes, including medical conditions, allergies, and infections. Some are caused by bacteria (such as <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/impetigo.html/">impetigo</a>), viruses (<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/chicken-pox.html/">chickenpox</a>, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/cold-sores.html/">cold sores</a>, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/measles.html/">measles</a>), fungi (ringworm), and skin parasites (<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/head-lice.html/">lice</a>, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/bedbugs.html/">bedbugs</a>, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/scabies.html/">scabies</a>). Often, the specific cause is unknown.</p> <p>Rashes can be dry and scaly, red and itchy, wet and warm, crusty and blistered, or flat and painless. Some rashes form right away and others can take several days to appear.</p> <p>Common causes and types of rashes include:</p> <ul> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/diaper-rash.html/">diaper rash</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/eczema-atopic-dermatitis.html/">eczema</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/erythema-toxicum.html/">erythema toxicum</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hives.html/">hives</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/lyme.html/">Lyme disease</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/molluscum-contagiosum.html/">molluscum contagiosum</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/pityriasis-rosea.html/">pityriasis rosea</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/poison-ivy.html/">poison ivy</a></li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/roseola.html/">roseola</a></li> <li><a class="kh_anchor">tinea</a> (ringworm, athlete's foot, jock itch)</li> </ul> <h4>Treatment</h4> <p>Treatment, when needed, will depend on the cause of the rash.</p> <p>For rashes that may be&nbsp;caused by an allergen, such as&nbsp;hives, the doctor will try to find out which food, substance, medicine, or insect caused it so that it can be avoided in the future. Many fungal skin infections (like ringworm&nbsp;and athlete's foot) can be treated with&nbsp;over-the-counter topical antifungal&nbsp;creams and sprays.</p> <p>Itchiness often can be managed with home care like oatmeal baths, cold compresses, anti-itch creams, or calamine lotion. More severe cases might be treated with an antihistamine (either as a&nbsp;liquid or pill) to decrease itching and redness.</p> <p>Contact a doctor if your child has a rash and also seems ill or has a&nbsp;<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/fever.html/">fever</a>, or if the rash lasts more than a week.</p> <h3 id="a_Keep_in_Mind">Keep in Mind</h3> <p>Many rashes can be itchy, but it's important to try not to scratch them. Scratching can make a rash take longer to heal and can lead to infection or scarring.</p> <div id="khcontent"> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p> </div>
