Rashes with no fever or itching
Milia (blocked oil glands)
Up to 1 in every 2 newborn babies develop small white spots called milia on their face, especially on the nose. These are just blocked pores, and they’re not itchy or contagious. They usually clear up without treatment within a few weeks.
Erythema toxicum
Many newborns develop a blotchy red skin reaction called erythema toxicum, which can appear between 2 days and 2 weeks after birth. Flat, red patches or small bumps often first appear on the face and spread to the body and limbs. The rash is harmless, not contagious, and will clear after a few days or a week.
Baby acne
Some babies get pimples on their cheeks and nose in the first three months of life. These pimples normally disappear without any treatment, usually within a few months.
Nappy rash
Nappy rash is inflammation of the skin in the nappy area. It can look red, sore and inflamed. Nappy rash is usually caused by urine (wee) or faeces (poo) irritating the skin.
To avoid nappy rash, keep the nappy area clean and dry with frequent nappy changes and nappy-free time. You can help protect the skin by putting on a barrier cream such as zinc or soft white paraffin at each nappy change.
Persistent nappy rash can be treated with a medicated cream. Don’t use talcum powder or antiseptics to treat nappy rash. If your baby develops a fungal infection, you’ll need to use an antifungal ointment. Ask your doctor or pharmacist for advice.
Erythema multiforme (minor)
Erythema multiforme is a rash triggered by an infection (most commonly herpes simplex virus), medicine or an illness. Your baby might feel unwell or have a mild fever before the rash appears. Red spots develop on the hands, feet, arms and legs and spread symmetrically across both sides of the body. The spots often become raised or blistered and then develop into classic target-like lesions.
Erythema multiforme is not contagious, and usually resolves without treatment in 3 to 6 weeks.
Keratosis pilaris (‘chicken skin’)
Keratosis pilaris is a harmless condition where the skin becomes rough and bumpy, as if permanently covered in goose pimples. These bumps most commonly occur on the upper arms and thighs. You can try several things to help the rash to clear up, including moisturising regularly.
Rashes that might be itchy
Eczema (Atopic dermatitis)
Eczema is a very common skin condition affecting 1 in 3 Australians. It causes the skin to become itchy, red, dry and cracked, often in the creases at the knees and elbows.
Eczema commonly starts before a baby is 12 months old. Eczema follows a relapsing-remitting course. This means that there are flare-ups of the rash, followed by periods where there is no rash or a minimal rash.
Eczema management includes preventative treatment such as avoiding skin irritants, moisturising regularly and using bath oil. Treatment of flare-ups includes using steroid and anti-inflammatory creams.
Ringworm (tinea)
Ringworm is a common, contagious skin infection that causes a ring-like red rash with a clear centre. It commonly occurs on the scalp, feet and groin, but it can appear almost anywhere on the body.
Ringworm is caused by a fungus, not a worm, and is usually treated with over-the-counter antifungal creams. You should keep your child home from childcare or school until a day after you have started treatment to prevent spreading the infection.
Prickly heat (heat rash)
Heat rash might appear if your baby gets hot in a humid environment. The rash shows as tiny red bumps or blisters on the skin, which can be very itchy. Cooling your baby down and avoiding humidity is the best way to prevent heat rash, which usually clears within 2 to 3 days without treatment.
Impetigo (school sores)
Impetigo is a highly contagious bacterial infection of the skin. It causes red sores and blisters that form a yellow crust. It is very common in children aged 2 to 6, and it is not usually serious in this age group, but it can be dangerous for newborn babies.
If your child has impetigo, you should see your doctor, who might prescribe an antibiotic cream, ointment or tablet. This should clear the infection within 7 to 10 days. Keep your child home from childcare or school and away from young babies until the sores have dried up, usually a few days after treatment starts.
Hives (urticaria)
Hives is a raised, red, itchy rash. It is common on the chest, stomach and back, as well as the throat and limbs, but it can appear on any part of the body. Hives usually disappears within a few days without any treatment. Antihistamines can be given to relieve itching. If the rash doesn't go away, you should see your doctor.
Hives isn’t usually serious, but it can be a sign of a more serious allergic reaction (anaphylaxis). If your child develops hives after eating, or together with other symptoms such as vomiting, dizziness or trouble breathing, you should seek urgent medical attention.
If your child has symptoms of a serious allergic reaction (anaphylaxis), call triple zero (000) immediately and ask for an ambulance.
Pityriasis rosea
Pityriasis rosea is a mild skin rash that sometimes appears after a sore throat, cold or fever. It begins with a single pink or tan-coloured patch on the chest or back. Red, oval-shaped patches, which may be itchy, then appear on the chest or back and limbs over the next weeks.
The exact cause of pityriasis rosea is unclear, and it is not thought to be contagious. The rash usually clears up within a couple of months without treatment.
If you are pregnant, pityriasis rosea can in rare cases lead to complications. See your doctor if you are pregnant and have contact with a child who has pityriasis rosea.
Molluscum contagiosum
Molluscum contagiosum is a viral skin infection that is spread by skin-to-skin contact or by sharing swimming pool water, bath water or towels.
Molluscum contagiosum spots look like pimples and grow into round pearly white lumps, usually 2 to 5 millimetres in size. They can be itchy. They usually heal without treatment within 6 months, but sometimes longer.
Rashes with fever
Slapped cheek disease (fifth disease)
Slapped cheek disease is a viral infection that mainly affects pre-school and school-age children. It typically causes a bright red rash on both cheeks that spreads as a ‘lacy’ rash on the body and limbs. Occasionally, it causes a fever.
Slapped cheek disease is usually mild and clears up in a few days without treatment. The child is contagious before the rash appears, but not once it has appeared.
If you are pregnant and catch the virus, it may cause a type of anaemia in your unborn baby. It can also cause miscarriage. If you suspect you or your child has slapped cheek disease, you should avoid contact with people who might be pregnant.
Hand, foot and mouth disease
Hand, foot and mouth disease is a mild but highly contagious viral illness. It causes a rash on the palms of the hands and soles of the feet and blisters in the mouth. It is not the same as the foot-and-mouth disease that affects farm animals.
The disease is common in childcare and kindergartens. Your child might feel unwell and have a fever and blisters on the hands and feet and in the mouth and in the nappy area. The illness usually lasts about 7 to 10 days. Children with hand, foot and mouth disease should stay away from childcare or school until all the blisters have dried up.
Hand, foot and mouth disease usually resolves on its own without complications. In rare cases, it can be more serious, especially if you have a weakened immune system or are pregnant. Complications can include infections of the brain and heart muscle and miscarriage.
Roseola infantum
Roseola infantum is a contagious viral infection that can cause cold-like symptoms and a high fever. The high fever may last for a few days. Roseola infantum can also cause some children to have a febrile convulsion (seizure).
Children with roseola infantum develop a rash after the fever has resolved. The rash looks like raised pink spots that start on the chest, stomach and back and spread to the limbs. The child is contagious before the rash appears, but not after. The rash usually lasts 3 to 5 days.
Febrile convulsions can look scary but are generally not harmful.
If your child has a seizure, call triple zero (000) immediately and ask for an ambulance.
When to seek help
Many babies develop a skin rash in their first days or weeks of life as their sensitive skin adapts to a new environment. Most rashes are harmless and go away on their own, but if your baby seems unwell, or if you’re worried, you should see your doctor. They can advise about the cause and whether treatment is necessary.
Whatever their age, you should take your child to the doctor if they have a rash and persistent high temperature, cold or cough symptoms or swollen neck glands.
Treatment of common childhood rashes
If you think your child might be contagious, they should stay at home. Keep them away from school, childcare and other children. You should also keep them away from people who are pregnant, or who might be pregnant, since some childhood infections can cause serious problems in unborn babies.
You can use paracetamol or ibuprofen (in babies aged over 3 months) to reduce fever — read the packet instructions carefully to ensure your child receives the right amount for their age and weight.
Your pharmacist can advise you on treating the symptoms of common rashes. For example, you can use over-the-counter creams to prevent itchiness.

Rash or Redness - Widespread
Is this your child's symptom?
- Red or pink rash over large parts or most of the body (widespread)
- Sometimes, just on hands, feet and buttocks - but same on both sides of body
- Small spots, large spots or solid red skin
Causes of Widespread Rash or Redness
- Viral Rash. Most rashes are part of a viral illness. Viral rashes usually have small pink spots. They occur on both sides of the chest, stomach and back. Your child may also have a fever with some diarrhea or cold symptoms. They last 2 or 3 days. More common in the summer.
- Roseola. This is the most common viral rash in the first 3 years of life. (See details below).
- Chickenpox. A viral rash with a distinctive pattern. (see that Care Guide)
- Hand-Foot and-Mouth Disease. A viral rash with a distinctive pattern. It starts with tiny red spots and blisters on the palms and soles. (see that Care Guide)
- Monkeypox. A rare viral rash that often starts on the face or genital area. It then spreads to the arms and legs. Not usually seen in children unless someone in the home has monkeypox.
- Scarlet Fever. Scarlet Fever is a speckled, red rash all over. Has a sandpaper feel. Caused by the Strep bacteria. Starts on upper chest and quickly spreads to lower chest and stomach. No more serious than a Strep throat infection without a rash.
- Drug Rash. Most rashes that start while taking an antibiotic are viral rashes. Only 10% turn out to be allergic drug rashes. (see details below)
- Hives. Raised pink bumps with pale centers. Hives look like mosquito bites. Rashes that are bumpy and itchy are often hives. Most cases of hives are caused by a virus. Hives can also be an allergic reaction. (See that Care Guide for details)
- Heat Rash. A fine pink rash caused by overheating. Mainly involves neck, chest and upper back.
- Insect Bites. Insect bites cause small red bumps. Flying insects can cause many bumps on exposed skin. Non-flying insects are more likely to cause localized bumps.
- Hot Tub Rash. Causes small red bumps that are painful and itchy. Mainly occurs on skin covered by a bathing suit. Rash starts 12-48 hours after being in hot tub. Caused by overgrowth of bacteria in hot tubs.
- Petechiae Rash (Serious). Petechiae are purple or dark red colored tiny dots. They come from bleeding into the skin. Scattered petechiae with a fever are caused by Meningococcemia until proven otherwise. This is a life-threatening bacterial infection of the bloodstream. Peak age is 3 to 6 months old. Unlike most pink rashes, petechiae don't fade when pressed on.
- Purpura Rash (Serious). Purpura means bleeding into the skin. It looks like purple or dark red larger spots. Widespread purpura is always an emergency. It can be caused by a bacterial bloodstream infection. Rocky Mountain Spotted Fever is an example.
- Blister Rash (Serious). Widespread blisters on the skin are a serious sign. It can be caused by infections or drugs. Stevens Johnson Syndrome is an example.
- Caution. All widespread rashes with fever need to be seen. They need to be diagnosed. Reason: some serious infections that can cause this type of rash.
Drugs and Rashes
- Prescription medicines sometimes cause widespread rashes. Some are allergic, but most are not.
- Non-prescription (OTC) medicines rarely cause any rashes.
- Most rashes that occur while taking an OTC medicine are viral rashes.
- Fever medicines (acetaminophen and ibuprofen) cause the most needless worry. Reason: most viral rashes start with a fever. Hence, the child is taking a fever medicine when the rash starts.
- Drug rashes can't be diagnosed over the phone.
Roseola - A Classic Rash
- Most children get Roseola between 6 months and 3 years of age.
- Rash: pink, small, flat spots on the chest and stomach. Then spreads to the face.
- Classic feature: 3 to 5 days of high fever without a rash or other symptoms.
- The rash starts 12 to 24 hours after the fever goes away.
- The rash lasts 1 to 3 days.
- By the time the rash appears, the child feels fine.
- Treatment: the rash is harmless. Creams or medicines are not needed.
Localized Versus Widespread Rash: How to Decide
- Localized means the rash occurs on one small part of the body. Usually, the rash is just on one side of the body. An example is a rash on 1 foot. Exceptions: athlete's foot can occur on both feet. Insect bites can be scattered.
- Widespread means the rash occurs on larger areas. Examples are both legs or the entire back. Widespread can also mean on most of the body surface. Widespread rashes always occur on matching (both) sides of the body. Many viral rashes are on the chest, stomach and back.
- The cause of a widespread rash usually spreads through the blood stream. Examples are rashes caused by viruses, bacteria, toxins, and food or drug allergies.
- The cause of a localized rash usually is just from contact with the skin. Examples are rashes caused by chemicals, allergens, insect bites, ringworm fungus, bacteria or irritants.
- This is why it's important to make this distinction.

Care Advice for Widespread Rashes
- What You Should Know About Widespread Rashes:
- Most rashes with small pink spots all over are part of a viral illness.
- This is more likely if your child has a fever. Other symptoms (like diarrhea) also point to a viral rash.
- Here is some care advice that should help until you talk with your doctor.
- Non-Itchy Rash Treatment:
- If you suspect a heat rash, give a cool bath.
- Otherwise, no treatment is needed.
- Itchy Rash Treatment:
- Wash the skin once with soap to remove any irritants.
- Steroid Cream. For relief of itching, use 1% hydrocortisone cream (such as Cortaid). Put it on the most itchy areas. No prescription is needed. Do this 3 times per day.
- Cool Bath. For flare-ups of itching, give your child a cool bath. Do not use soap. Do this for 10 minutes. Caution: avoid any chill. Option: Can add 2 ounces (60 mL) of baking soda per tub.
- Scratching. Try to keep your child from scratching. Cut the fingernails short. Reason: prevents a skin infection from bacteria.
- Allergy Medicine for Itching. If itching becomes severe, give an allergy medicine, such as Benadryl. No prescription is needed. Age limit: 1 and older. If needed longer than a few days, switch to a long-acting antihistamine, such as Zyrtec. Age limit: 2 and older.
- Fever Medicine:
- For fevers above 102° F (39° C), give an acetaminophen product (such as Tylenol).
- Another choice is an ibuprofen product (such as Advil).
- Note: Fevers less than 102° F (39° C) are important for fighting infections.
- For all fevers: Keep your child well hydrated. Give lots of cold fluids.
- Return to School:
- Most viral rashes can be spread to others (especially if a fever is present).
- If your child has a fever, avoid contact with other children. Also, avoid pregnant women until a diagnosis is made.
- For minor rashes, your child can return after the fever is gone.
- For major rashes, your child can return to school after the rash is gone. If your doctor has given medical clearance, your child can return sooner.
- What to Expect:
- Most viral rashes go away within 48 hours.
- Call Your Doctor If:
- You think your child needs to be seen
- Your child becomes worse
And remember, contact your doctor if your child develops any of the 'Call Your Doctor' symptoms.

Causes of a rash in children
Naturally, only a pediatrician, dermatologist or allergist can correctly determine the cause of the rash , diagnose and prescribe treatment for a child. But provide initial assistance, relieve itching and the parents themselves can help the baby, knowing the main signs and causes of rash . At the first stage, it is important to determine the nature of the rash - infectious , allergic or none of the above.
Causes of rashes in children:
1. Newborn acne . For the first time may occur in newborns at the age of 1 - 2 months. As a rule, such rashes are hormonal in nature, are not contagious and are not allergic . A rash in the form of pimples, sometimes with a white dot in the middle, appears on the head, body of the baby. If there are no purulent compartments, then the rash goes away on its own and does not require treatment. Acne can also occur in teenagers. They most often appear on the face in the form of black dots and are associated with hormonal changes in the body of a teenager and an increased work of the sebaceous glands. To prevent acne, there are cosmetic lotions, washing gels and other products. In case of inflammation, it is better to seek advice from a pediatric dermatologist or cosmetologist, because. antibiotic treatment may be needed; nine0003 2. Urticaria is an allergic reaction on the child's skin, accompanied by itching and the appearance of blisters on various parts of the body, in some cases the temperature may rise and the child's stool is disturbed. The blisters appear suddenly and can disappear just as quickly, but sometimes they disappear only after a few days. The causes of urticaria can be various factors: hormonal disorders, malfunctions of the liver, kidneys, consumption of foods that caused an allergic reaction (fish, eggs, citrus fruits, etc.), insect bites, reaction to sunlight, temperature changes, emotional stress etc. Urticaria can be chronic does not go away for a long time, and acute disappears after a few hours. For the treatment of urticaria, it is important to identify the underlying cause that caused it; 3. Food allergy manifests as pinkish-red spots. It is slightly convex, edematous in places of scratching and is accompanied by itching. It is localized, as a rule, on the baby's cheeks, but can also appear on other parts of the body. It can occur in both infants and adolescents. If the baby is breastfed, then the allergy that has arisen is associated with the products consumed by the mother. If the newborn is artificially fed, then an allergic reaction may appear on the mixture. In older children, food allergies can be caused by fish, eggs, nuts, chocolate, strawberries, and other foods; nine0003 Allergy, as a rule, is accompanied by edema, which in turn, if not properly treated and provided with untimely assistance, cause suffocation . If an allergy of any nature occurs, a pediatrician's consultation is required to help in choosing the optimal mixture for the baby, or a pediatric dermatologist - allergist for referral to laboratory tests of older children ; 4. Household allergies . It can occur in both newborns and older children. It usually appears as pimples all over the body and is accompanied by lachrymation, sneezing. The causes of such a reaction of the body can be washing powder and other detergents, dust, plants, animal hair, etc. An allergic rash differs from an infectious rash in that the child does not have a temperature with it, he does not have general ailments, there is no loss of appetite, drowsiness; 5. Prickly heat . It occurs mainly in infants. It manifests itself in the form of red pimples all over the body, especially in the inguinal zone. The affected areas must be smeared with a special baby cream, air baths more often for the baby and a diaper change; nine0003 6. Roseola (erythema infectiosum) is an acute childhood viral disease affecting only children under 2 years of age. Very often, roseola is confused with SARS or rubella . At the beginning of the illness, the baby's temperature rises sharply, which lasts 3-5 days, and after that the child becomes covered with a red-pink rash that disappears in 5-7 days. This is not a dangerous disease, it does not require treatment, and if it occurs, the child should be given only antipyretic drugs; 7. Windmill . This is a common childhood infectious disease that requires treatment. The incubation period of this disease can last from 11 to 21 days. Occurs at any age. It is accompanied by a rash on the skin and mucous membranes in the form of red spots, in the center of which blisters with a yellowish liquid are localized. Accompanied by itching. As the disease progresses, the blisters burst, crusts form, leaving scars if the child has scratched the blister and brought the infection. The disease can also cause fever and headache; nine0003 8. Measles is an acute infectious disease that is quite rare due to the use of vaccinations. In addition, this virus is rarely activated in babies under 8 months old, because. they are protected by their mother's immunity. The disease begins with symptoms of a common cold - coughing, lacrimation, sneezing and fever up to 40 C. Then the child develops white spots on the mucous surface of the cheeks, nasal discharge, severe headache, photophobia. Then, within a few days, red spots of various shapes appear on the face, neck, near the head and further throughout the body. The disease is contagious within a week of the onset of the first symptoms. The virus is dangerous with complications such as: meningitis , pneumonia , development of deafness, brain damage and even death; 9. Scarlet fever is an acute infectious streptococcal disease. Begins with sore throat, high temperature, enlarged tonsils , in some cases with plaque. Then a small dotted rash appears on the back, chest, knees, armpits, groin and quickly spreads throughout the body and face. Only the area around the mouth remains white. Throat and tongue become very red. By the end of the disease, peeling of the skin on the toes and hands begins; nine0003 10. Rubella is an acute infectious disease . The disease begins with a slight increase in temperature and enlargement of the lymph nodes in the parotid and cervical region. A small rash also appears on the face and behind the ears, and then all over the body. Rubella is very dangerous for pregnant women, and complications can occur in older children and adolescents. In children, the disease proceeds in a fairly mild form; 11. Meningitis is an inflammation of the membranes of the brain and spinal cord. Rash in meningitis is not the main symptom. However, with this disease, rashes appear on the back of the throat, as well as on the hips, back, buttocks in the form of a red rash of various shapes. Symptoms of meningitis include very high fever, severe headache, vomiting, photophobia, and neck muscle tension. At the slightest suspicion of meningitis, parents should immediately consult a doctor. Timely help with this disease will save the child's life; nine0003 12. Streptoderma is a skin infection caused by Staphylococcus aureus. The disease affects, as a rule, the paranasal and perioral region. In the beginning, redness appears around the nose and mouth, then small bubbles with liquid. When they burst, yellow crusts remain. The disease may be accompanied by fever; 13. Herpes is an infectious disease accompanied by the appearance of blisters on the skin and mucous membranes, in children it is most often located on the lips. This disease is extremely rare in newborns, because. they are given maternal immunity. It affects children from 3 to 4 years of age. In addition to a rash, the disease may be accompanied by a sore throat, fever. nine0003 There are a lot of skin rashes and diseases in children, they can be very similar, but some are completely harmless to your child's health, while others pose a threat not only to the general condition, but also to the child's life! Do not take risks, and if you have any doubts, if any spots, rashes and other symptoms appear, contact your pediatrician, who, if necessary, will refer you and your child to a pediatric dermatologist, allergist, neurologist or other highly specialized specialist, depending on the nature of the rash and the severity of the skin disease.
