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.

Nappy rash - NHS

Around 1 in 4 babies and toddlers in nappies have nappy rash at any one time. It doesn't usually develop in newborns, but all babies can get nappy rash.

Nappy rash can be caused by:

your baby's skin being in contact with wee or poo for a long time
the nappy rubbing against your baby's skin
not cleaning the nappy area or changing the nappy often enough
soap, detergent or bubble bath
alcohol-based baby wipes
some types of medicines, such as antibiotics or laxatives (used to make a baby poo more often)

There may be red patches on your baby's bottom, or the whole area may be red. Their skin may look sore and feel hot to touch, and there may be spots, pimples or blisters.

Most babies with mild nappy rash don't feel sore, but if the rash is severe your baby may feel uncomfortable and be distressed.

Treating nappy rash

If your baby gets nappy rash, you can usually treat their skin yourself.

If the rash isn't upsetting your baby, at each nappy change apply a thin layer of a barrier cream to protect their skin. Ask your health visitor or pharmacist to recommend one.

Follow this advice to help look after your baby's skin.

Change wet or dirty nappies as soon as possible.
Clean the whole nappy area gently but thoroughly, wiping from front to back. Use water or fragrance-free and alcohol-free baby wipes. Read more about how to clean your baby and change your baby's nappy.
Bath your baby daily – but avoid bathing them more than twice a day as that may dry out their skin.
Dry your baby gently after washing them – avoid vigorous rubbing.
Lie your baby on a towel and leave their nappy off for as long and as often as you can to let fresh air get to their skin.
Do not use soap, bubble bath, or lotions.
Do not use talcum powder as it contains ingredients that could irritate your baby's skin.
Make sure your baby’s nappy fits properly. If it is too tight then it can irritate the skin and if it is too loose, then the nappy will not be able to soak up pee properly.

Nappy rash usually clears up after about 3 days if you follow this advice. You should keep following this advice as this will help prevent nappy rash from coming back.

If the rash is causing your baby discomfort, your health visitor or pharmacist can recommend a nappy rash cream to treat it.

You should apply the cream first and wait a few minutes before you apply the barrier cream.

Other rashes in the nappy area

If the rash doesn't go away or your baby develops a persistent bright red, moist rash with white or red pimples that spreads into the folds of their skin, they may have an infection.

Ask a pharmacist or health visitor for advice. The pharmacist may recommend a cream for you to use.

If the rash is severe, take your baby to the GP who may prescribe cream or medicine. Follow a GP's instructions on whether and when to apply barrier cream as well as the prescribed cream.

It's normal for babies to develop skin rashes, but it's important to know the difference between a minor irritation and a condition that requires attention.

Rashes in infants | Rassvet Clinic

Babies are generous with various rashes. According to the "good" tradition, most of them are considered allergic with all the consequences - a strict diet for a nursing mother, transfer to artificial feeding, prescription of therapeutic mixtures, etc. In fact, true allergic rashes in infants are not so common. Allergic diseases affecting the skin in infants include: atopic dermatitis, acute urticaria and angioedema. Acute urticaria is extremely rare in infants - this is an acute allergic reaction in the form of peculiar rashes like blisters (as with a nettle burn, hence the name), which suddenly appear on the skin and just as suddenly disappear without leaving any trace, usually do not exist on the skin for longer than a day and are accompanied by severe itching, which manifests itself in the general anxiety of the child. The most common causes are dietary proteins (such as cow's milk), viral infections, insect bites, and drugs (such as antibiotics). In severe cases, it may be accompanied by swelling and redness of the soft tissues of the face, neck, larynx, arms, legs, genitals or abdominal cavity - Quincke's edema, which requires immediate medical attention.

Let's look at what is most often undeservedly called an allergy:

Toxic erythema newborns - a transient benign rash, the exact cause of the appearance is unknown (possibly due to skin irritation by environmental factors).

Appears at birth or in the first 24-48 hours of life. Localization - face, trunk, limbs, except for the palms and soles. Disappears on its own within 5-7 days, sometimes 3 weeks. Does not require treatment.

Neonatal acne (acne infancy, neonatal pustulosis) is caused by androgen stimulation of the baby's sebaceous glands.

Peak rash falls on the 3rd week of life. It is localized more often on the face, sometimes spreads to the scalp, less often to the collar zone. They resolve spontaneously. The skin needs cleansing and moisturizing, in some cases, the application of
treatment creams may be required.

Sweating rash , which occurs in poorly "ventilated" areas as a result of blockage of the sweat glands. May occur at any age.

Localization - skin folds, buttocks and back surface of the body, sometimes the face (after sleep). Depending on the depth of the lesion, it happens - crystal prickly heat, prickly heat, deep prickly heat (superficial).

The duration of the rash is from several hours to several days.

Treatment - cool water baths, air baths, prevention of overheating. Lotions containing calamine and creams with corticosteroids and antibiotics may be used to treat some cases of red and deep prickly heat.

Seborrheic dermatitis is a skin disorder that develops in areas rich in sebum. The exact cause is unknown (a certain role is assigned to the skin saprophyte - the Malassezia fungus, which grows well and multiplies in the sebaceous secretion).

It can be foci or widespread, dermatitis with bran-like scales, which can form a crust (“bonnet”, gneiss) on the scalp.

Favorite localization - scalp, face, folds (!).

May begin at 1-2 weeks of age or later, resolve spontaneously within weeks or months.

Treatment consists of softening the crusts with oil or cream and then removing them, moisturizing the skin and, in some cases, applying antifungal and anti-inflammatory creams.

Simple contact dermatitis is a non-specific skin injury due to prolonged or repeated exposure to a variety of substances - saliva, fruit juices, foaming bath products, detergents (their residues on the walls of the bath), etc. In infants, saliva is often causes dermatitis in the area of contact with the nipple and in the folds of the neck.

Usually, removal of the damaging agent and short-term use of anti-inflammatory creams will quickly lead to recovery, but some children are so sensitive that it is almost impossible to identify the causative factor.

Diaper dermatitis (contact dermatitis prototype) is a skin lesion that occurs under the influence of physical (overheating), chemical, enzymatic (contact with sweat, urine and feces) and microbial factors. Localization - the area of the diaper or diaper fit.

Treatment is carried out using the abbreviation ABCDE (air, barrier, cleansing, diaper, education) - air, barrier, cleansing, diaper and parent education. Frequent diaper changes, washing the skin and drying it thoroughly help. Dermatitis is effectively prevented by the application to clean skin of products that completely cover it (Vaseline, zinc paste). In stubborn cases, medicated creams containing corticosteroids, antibiotics, or antifungals may be recommended.

And now a few words about AD:

Atopic dermatitis is a chronic allergic inflammation of the skin, genetically determined, associated with the loss of the skin barrier and, therefore, accompanied by dryness, itching and various rashes. In a third (!) of cases, it is combined with food allergies (the most common "culprits" are cow's milk, chicken eggs, wheat, fish, soy, nuts).

Starts more often not earlier than 3 months of life.

The most common localization up to 2-3 years is the face (cheeks, forehead, chin), convex parts of the limbs (extensor surfaces) and trunk, never in babies in folds (!).

Exacerbations are provoked by various factors - stress, dry air, sweat, food (histamine liberators), infections, contact with tobacco smoke, animal hair, rough fabrics, detergent residues on clothes, etc.

Treated with careful skin care and using anti-inflammatory creams.

There are also:

Pseudo-allergic reactions are reactions that look similar to allergic reactions (for example, various rashes), but are not such, due to the non-immune mechanism of their development.

The reason is an increased content of histamine (tyramine, serotonin) in foods, or the ability of foods to increase the release of these substances in the body, or their increased absorption, due to the pathology of the gastrointestinal tract (fermentopathy, inflammation in the intestinal wall, etc.). ). Such products include chocolate, cocoa, strawberries, citrus fruits, honey, sauerkraut, marinades and spices, seafood, fish, caviar, pork, mushrooms, cheeses, nuts, smoked meats, preservatives, dyes and flavor enhancers.

Treatment includes dietary advice, skin care, and in some cases, antihistamines and anti-inflammatory creams.

Clinical manifestations of atopic dermatitis, simple contact dermatitis in highly sensitive children and the manifestation of pseudo-allergic reactions are very similar to each other, so the main task remains to create a "skin barrier" by constantly moisturizing the skin with the help of emollients, stopping exacerbation with anti-inflammatory creams and eliminating exacerbation-provoking factors .

And the last:

Skin infections - herpesvirus, staphylococcal pemphigus, candidiasis also occurs in infants, do not forget about them. It is worth contacting a doctor immediately if the child is lethargic, has a fever, refuses to breast or bottle, skin rashes are accompanied by pus or are covered with purulent crusts, there are blisters or a group of bubbles, erosion (violation of the integrity of the skin), severe swelling and redness of the skin.
