Introduction

Parents frequently worry about skin rashes in their children since they may be a sign of a number of underlying medical issues. Rashes can take many different shapes, from red patches on cheeks to itching hives, and they can occasionally be frightening or confusing. Maintaining your child's comfort and health can be greatly improved by knowing what causes these rashes and how to treat them. 

Common types of skin rashes in children

Diaper rash

Description

Diaper rash is common in babies and usually presents with irritation in the diaper area.

Causes

It occurs due to trapped moisture in the diaper area that leads to irritation which might also cause the growth of fungi and bacteria.

Prevention

Keep the diaper area clean and dry by changing the diaper frequently. Allowing the skin to air out for a short time during diaper changes can also help, applying ointments or creams with zinc oxide or petroleum jelly is advised to protect the skin.¹

Eczema (Atopic dermatitis)

Description

The common pediatric rash known as eczema is characterized by extremely dry, itchy, and scaly skin. Although it usually affects younger children, some people may have it for the rest of their life.

Causes

It is speculated that an overactive immune system response causes eczema. It is especially prevalent in people who have asthma or allergies.

Management strategies

Eczema doesn't have a cure, but it can be managed with lotions, which are used to moisturize the cracked skin and oral antihistamines or steroid creams are used to reduce itching. Eczema on its own rarely presents as an emergency, it can occasionally result in bacterial infections such as MRSA, which need to be treated.²

Heat rash (Prickly heat)

Description

Heat rash (prickly heat or miliaria) occurs due to blocked sweat gland pores. It affects infants and young children, presenting as little pink or red bumps or blisters, especially on the areas of the neck, elbows, armpits, or thighs, and usually in the areas where the skin folds or is exposed to clothing.

For relief

• Allow the areas affected to air out without clothing and avoid applying skin ointments
• Wash sweat-soaked areas with cool water and pat them dry
• Lightweight, breathable clothing must be used³

Contact dermatitis

Description

Contact dermatitis is a localised skin reaction to a foreign material. Typically arising in the area that was in contact with the irritant, the rash may display blistering, redness, raised bumps, or hives. It itches a lot, usually.

Common triggers

Triggers could be poison ivy, perfumes, lotions, laundry detergents, or bubble baths.

Treatment

• Remove the offending agent
• Oral antihistamines like Benadryl are used to alleviate itching¹

Chickenpox

Description

This condition first presents as a rash on the face, chest, and back that can eventually extend to the entire body. The rash caused by varicella zoster virus develops into blisters that are painful and filled with fluid, which finally scabs over.

Management

For itching, you would be advised to take antihistamines for relief; for fever,  acetaminophen would be advised. Children may transmit until all blisters have crusted over. Usually, chickenpox goes away on its own in one to two weeks.¹

Hand, foot, and mouth disease

Description

Typically affecting young children in the summer and early fall this disease starts off with symptoms similar to a regular cold, such as fever, sore throat, and runny nose. Followed by developing a rash with small blisters at the mouth, fingers, palms, soles of the feet, and buttocks. Symptoms are more prominent during the first couple of days however they resolve in a week.

Causes

Enterovirus coxsackie spreads easily in daycare centres, schools and other gatherings.

Management

• Monitor symptoms: If the child refuses to drink fluids or if the fever lasts more than three days, get in touch with a paediatrician
• Reduce the pain: For fever and pain relief, the use of ibuprofen or acetaminophen is advised. Avoid any mouthwash as it could sting; soothing treatments can help with mouth ulcers. It is also advised to keep a check on the child's fluid intake to prevent dehydration. If symptoms of dehydration develop, get medical attention³

Fifth disease (Slapped cheek syndrome)

Description 

The child's cheeks develop a bright red rash as a sign of the fifth disease, commonly referred to as "slapped cheek disease." Children may have a high temperature and other mild symptoms in addition to the rash. The facial rash goes away after a few days, and the arms and legs may develop pink, lace-like patches.

Causes

The fifth disease is caused by the Parvovirus B19, which is spread through respiratory droplets and direct contact.

Management

Treatment focuses on comfort measures, such as non-steroidal anti-inflammatory drugs (NSAIDs) for fever and pain relief, as well as anti-itch creams or antihistamines to manage itching.¹

Hives (Urticaria)

Description: 

Hives, or urticaria, are raised, red, blotchy areas of skin that are extremely itchy. They can often be brought on by viral infections, dietary allergies, or allergens in the air. It is possible for hives to come and go, migrating throughout the body.

Causes

Hives can be caused by allergic reactions to certain foods, environmental allergens, or even viral infections.

Treatment

Oral antihistamines are the primary treatment for hives. If hives are accompanied with wheezing, shortness of breath, swollen lips, difficulty swallowing, or difficulty breathing, it may indicate a serious emergency. In these situations, emergency medical care is necessary. It is advised to have an Epi-pen with you in case of known severe allergies so that you may quickly reverse severe allergic responses with a dosage of epinephrine.²

Impetigo

Description

The most common symptoms of impetigo are red bumps, blisters, or crusty areas on the skin. Although they can form whenever the skin becomes irritated, these lesions are most frequently found around the mouth and nose.

Cause

The infection is caused by bacteria, either Group A Streptococcus or Staphylococcus aureus. It's most frequently seen in children aged 2 to 5 years, though it can occur at any age.

Treatment

Treatment often involves antibiotics, which can be applied topically or taken orally.

Less Common but Serious Skin Rashes³

Measles

Description

The Morbillivirus, which causes measles, is a highly contagious viral infection. Usually, it begins as a rash on the face, usually in the area around the lips or behind the ears, and then moves down the body. The rash begins as flat red spots that may develop smaller raised white spots on top, sometimes joining together as they spread.

Management

Acetaminophen or NSAIDs can be used to treat symptoms like fever and achiness, even though measles must run its course and usually clears itself in two weeks. In the event that difficulties arise, immediate medical assistance is necessary.

Prevention

Vaccination is given around the age of 9 months to the baby.¹

Scarlet fever

Description

The infection often starts with fever, sore throat, and headache. A raised, red rash that usually begins on the neck and upper chest and spreads from there is the distinguishing characteristic. The skin may appear burnt and the rash has a rough, sandpaper-like texture. It's also typical to have a heated face and a pale region around the mouth.

Causes

This condition is caused by the same bacteria responsible for strep throat, group A Streptococcus.

Management

Scarlet fever is treated with antibiotics to eliminate the infection and prevent complications.¹

When to seek medical attention

• Breathing or swallowing difficulties accompanied by a rash
• fever accompanied by a bright red, flat rash that looks like tiny dots
• Bruising-like rash with a purple tinge
• Rash involving the lips, nose, or eyes, or with noticeable skin peeling²
