Healthy skin is a barrier between the inside of the body and the outside environment. A rash means that some change has affected the skin. In most cases, a rash is a minor problem or is part of an illness that will go away on its own. A rash may be caused by contact with a substance outside the body, such as poison ivy (contact dermatitiscontact dermatitis), or by other more serious illnesses, such as measlesmeasles or scarlet fever (strep throat with rash).
Generalized rashes are over the whole body. Ones caused by viruses are more common in babies and young children than in adults. A rash may be caused by a viral illness if the child also has a cold, a cough, or diarrhea, or is in a day care setting with other children who have viral illnesses. Most rashes caused by viruses aren't serious. They usually go away over a few days to a week. Home treatment is often all that's needed to treat these rashes.
After a child has had a rash caused by a virus, their body often builds an immunity to that virus. This immunity protects the child from getting that specific viral illness and rash again. Common rashes caused by viruses include:
ChickenpoxChickenpox (varicella). This rash is a common, contagious illness caused by a type of herpes virus.
Fifth diseaseFifth disease. This rash on the face looks like the cheeks have been slapped. It also causes a lacy, pink rash on the arms and legs, torso, and buttocks.
RoseolaRoseola (roseola infantum). This rash occurs about 3 days after a high fever.
Unknown virus. Sometimes the specific virus that causes a rash is never known.
Localized rashes affect one area of the body. They have many different causes and may go away with home treatment. Common localized rashes that occur during childhood include:
Diaper rashDiaper rash. This rash is caused by rubbing, moisture, chemicals, or bacteria in the baby's urine or stool; substances in disposable diapers; or soaps used to wash cloth diapers.
ImpetigoImpetigo. This bacterial skin infection is caused by strep or staph bacteria.
Heat rash (prickly heat)Heat rash (prickly heat). This rash often is caused by a well-meaning parent dressing a baby too warmly. But it can happen to any baby in very hot weather.
Cold soresCold sores. These are sometimes called fever blisters. Cold sores are clusters of small blisters on the lip and outer edge of the mouth. They are caused by the herpes simplex virus.
Contact dermatitisContact dermatitis. This rash is caused by contact with a substance, such as food, soap, or lotion, that causes an allergic reactionallergic reaction. Most contact dermatitis is mild. It goes away when your child's skin no longer comes in contact with the substance.
Cradle capCradle cap. This is an oily, yellow scaling or crusting on a baby's scalp. It's common in babies and is easy to treat. It's not a part of any illness. A baby can be well cared for and still get cradle cap.
Rashes that may require a visit to a doctor include:
Lyme disease. It's caused by a type of bacteria carried by deer ticks in some areas. A specific expanding red rash usually occurs at the site of the tick bite. It's followed by flu-like symptoms, such as a headache, chills, fever, body aches, and stiffness.
A rash that looks like a sunburn along with a fever of 102°F (38.9°C) or higher. This type of rash may be caused by a rare condition called toxic shock syndrometoxic shock syndrome.
A very rare and serious type of generalized red rash called toxic epidermal necrolysis (TEN). This type of rash may cause the skin to peel away, leaving large areas of tissue that weep or ooze fluid like a severe burn. TEN may occur after the use of some medicines.
To know how serious the rash is, other symptoms that occur with the rash must be looked at.

Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
Your age. Babies and older adults tend to get sicker quicker.
Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
Medicines you take. Certain medicines, such as blood thinners (anticoagulants), medicines that suppress the immune system like steroids or chemotherapy, herbal remedies, or supplements can cause symptoms or make them worse.
Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.
Try Home Treatment
You have answered all the questions. Based on your answers, you may be able to take care of this problem at home.
Try home treatment to relieve the symptoms.
Call your doctor if symptoms get worse or you have any concerns (for example, if symptoms are not getting better as you would expect). You may need care sooner.
If you're not sure if a child's fever is high, moderate, or mild, think about these issues:
With a high fever:
The child feels very hot.
It is likely one of the highest fevers the child has ever had.
With a moderate fever:
The child feels warm or hot.
You are sure the child has a fever.
With a mild fever:
The child may feel a little warm.
You think the child might have a fever, but you're not sure.
Abnormal bleeding means any heavy or frequent bleeding or any bleeding that is not normal for you. Examples of abnormal bleeding include:
Nosebleeds.
Vaginal bleeding that is different (heavier, more frequent, at a different time of month) than what you are used to.
Rectal bleeding and bloody stools.
Bloody or pink urine.
Gums that bleed easily when you eat or gently brush your teeth.
When you have abnormal bleeding in one area of your body, it's important to think about whether you have been bleeding anywhere else. This can be a symptom of a more serious health problem.
Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in children are:
Diseases such as diabetes, cystic fibrosis, sickle cell disease, and congenital heart disease.
Steroid medicines, which are used to treat a variety of conditions.
Medicines taken after organ transplant.
Chemotherapy and radiation therapy for cancer.
Not having a spleen.
Symptoms of infection may include:
Increased pain, swelling, warmth, or redness in or around the area.
Red streaks leading from the area.
Pus draining from the area.
A fever.
Temperature varies a little depending on how you measure it. For children up to 11 years old, here are the ranges for high, moderate, and mild according to how you took the temperature.
Oral (by mouth), ear, or rectal temperature
High: 104° F (40° C) and higher
Moderate: 100.4° F (38° C) to 103.9° F (39.9° C)
Mild: 100.3° F (37.9° C) and lower
A forehead (temporal) scanner is usually 0.5° F (0.3° C) to 1° F (0.6° C) lower than an oral temperature.
Armpit (axillary) temperature
High: 103° F (39.5° C) and higher
Moderate: 99.4° F (37.4° C) to 102.9° F (39.4° C)
Mild: 99.3° F (37.3° C) and lower
Note: For children under 5 years old, rectal temperatures are the most accurate.
Symptoms of serious illness in a baby may include the following:
The baby is limp and floppy like a rag doll.

Symptoms of serious illness may include:
A severe headache.
A stiff neck.
Mental changes, such as feeling confused or much less alert.
Extreme fatigue (to the point where it's hard for you to function).

Sudden tiny red or purple spots or sudden bruising may be early symptoms of a serious illness or bleeding problem. There are two types.
Petechiae (say "puh-TEE-kee-eye"):
Are tiny, flat red or purple spots in the skin or the lining of the mouth.
Do not turn white when you press on them.
Range from the size of a pinpoint to the size of a small pea and do not itch or cause pain.
May spread over a large area of the body within a few hours.
Are different than tiny, flat red spots or birthmarks that are present all the time.
Purpura (say "PURR-pyuh-ruh" or "PURR-puh-ruh"):

Rapid swelling of the throat, mouth, or tongue.
Trouble breathing.
Passing out (losing consciousness). Or you may feel very lightheaded or suddenly feel weak, confused, or restless.
Severe belly pain, nausea, vomiting, or diarrhea.
A severe reaction can be life-threatening. If you have had a bad allergic reaction to a substance before and are exposed to it again, treat any symptoms as an emergency. Even if the symptoms are mild at first, they may quickly become very severe.
A baby that is extremely sick:
May be limp and floppy like a rag doll.
May not respond at all to being held, touched, or talked to.
May be hard to wake up.
A baby that is sick (but not extremely sick):
May be sleepier than usual.
May not eat or drink as much as usual.

Antibiotics.
Aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve).
Pain medicines, such as codeine.
Seizure medicines.
Shock is a life-threatening condition that may occur quickly after a sudden illness or injury.
Babies and young children often have several symptoms of shock. These include:
Passing out (losing consciousness).
Being very sleepy or hard to wake up.

Self-Care
Most rashes will go away without medical treatment. Home treatment can often relieve pain and itching until the rash goes away.
After a rash appears, leave it alone as much as you can.
Use soap and water sparingly.
Leave the rash exposed to the air whenever you can.
Encourage your child not to scratch the rash.
But if your child has come in contact with a substance that may cause contact dermatitiscontact dermatitis, such as poison ivypoison ivy, wash the area with a lot of water right away. If you can, use liquid dish soap or a mild soap and very warm running water.
If your child has a rash, they should not be in contact with other children or anyone who is pregnant. Most viral rashes are contagious, especially if the person also has a fever.
In most cases, itching with a rash isn't serious, but it can be annoying. And it may make a rash more likely to get infected. Rashes caused by chickenpoxchickenpox, eczemaeczema, or contact dermatitis are much more likely to itch. Sometimes itching can get worse if you scratch.
Relief from itching
Try these tips to help relieve your child's itching from a rash.
Keep your child's fingernails clean and short.
Encourage your child not to scratch. Cover your baby's hands with socks to help keep your baby from scratching.
Keep your child out of the sun and in a cool place.
Heat makes itching worse.
Keep the itchy area cool and wet if your child is older than age 9 months.
Put cloths soaked in ice water on the rash a few times a day. Too much wetting and drying will dry the skin, which can increase itching. Don't put cloths soaked in ice water on the skin of a baby younger than 9 months. It may cause the baby's body temperature to go down.
Add a handful of oatmeal (ground to a powder) to your child's bath.
Or you can try an oatmeal bath product, such as Aveeno.
Dress your child in cotton clothing.
Don't use wool and synthetic fabrics next to the skin.
Use gentle soaps on your child's skin.
Examples of these soaps are Basis, Cetaphil, Dove, and Oil of Olay. Use as little soap as you can. Don't use deodorant soaps on your child.
Wash your child's clothes with a mild soap.
Try using ones such as CheerFree or Ecover. Rinse twice to remove all traces of the soap. Don't use strong detergents.
Don't let the skin get too dry.
Dry skin can make itching worse.
Try nonprescription medicines for itching.
Carefully read and follow all label directions on the medicine bottle or box.
Try calamine lotion for a rash caused by contact dermatitiscontact dermatitis, such as poison ivy or poison oak rashes.
For severe itching, apply hydrocortisone cream 4 times a day until the itch is gone.
Do not use the cream on children younger than age 2 unless your doctor tells you to do so. Do not use in the rectal or vaginal area on children younger than age 12 unless your doctor tells you to do so.
If itching affects your child's sleep, ask the doctor about giving your child an antihistamine that might reduce itching and make your child sleepy, such as diphenhydramine (Benadryl). Be safe with medicines. Read and follow all instructions on the label.
When to call for help during self-care
Call a doctor if any of the following occur during self-care at home:
New or worse signs of infection, such as warmth, redness, swelling, pus, or a fever.
Symptoms occur more often or are more severe.
