Skin rashes are a common reason for children visiting the pediatrician. It can be worrying when your child develops red, inflamed patches of skin and you are unsure of the cause.
Rashes can have various causes, such as:
- Viral infections (measles, roseola)
- Bacterial infections (scarlet fever)
- Allergic reactions (hay fever, hives)
- Irritating substances (detergents)
- Chronic skin conditions (eczema)
A widespread rash covering a large area of the body can be distressing. At Pediatric Practitioners of Oklahoma, we help determine when a rash should prompt a doctor’s visit or immediate care.
Understanding your child’s skin rash
Rashes can be caused by external irritants, internal conditions, or a combination of both. They can vary in severity and symptoms, such as dryness, itchiness, or inflammation.
Rashes may appear differently based on skin tone, but most clear up on their own. Some rashes may require medical attention or treatment.
Localized rashes
A localized rash affects one part of the body and is often caused by contact with an irritant. External factors like chemicals, allergens, or insect bites can lead to localized rashes.
Widespread rashes
Widespread rashes cover large areas of the body and may be symmetrical. These rashes are commonly caused by infections or allergies and require attention from a healthcare provider.
Treating rashes
For mild rashes, you can try using gentle moisturizers or over-the-counter creams to help relieve symptoms. Avoiding irritants and keeping the affected area clean and dry can also aid in healing.
If the rash persists, worsens, or is accompanied by other symptoms such as fever or difficulty breathing, seek medical attention promptly. A healthcare provider can diagnose the cause of the rash and recommend appropriate treatment options.
What can cause a widespread rash?
Widespread rashes are usually linked to internal factors affecting the skin. They are often a result of infections, allergies, or environmental factors.
Various infections can cause widespread rashes in children, indicating the need for medical evaluation.
Medical evaluation for a skin rash
Recognizing the seriousness of a widespread rash is essential. Monitoring your child’s overall health and behavior can help determine if medical attention is needed.
Some viral rashes are harmless and resolve on their own, while others may indicate a more severe underlying condition.
It is important to note the following when evaluating a skin rash:
- Check for any accompanying symptoms such as fever, pain, or discomfort.
- Keep track of when the rash first appeared and how it has progressed over time.
- Note any recent changes in diet, medications, or exposure to new substances.
- If the rash is spreading rapidly or causing severe itching or pain, seek medical attention immediately.
Rashes that require emergency care
If a widespread rash suddenly appears or is accompanied by other symptoms, seek emergency care. Certain signs like fever, difficulty breathing, or unusual skin changes warrant immediate attention.
A rash with specific characteristics may indicate a serious infection, requiring prompt medical intervention.

Hives
Hives, characterized by itchy red welts on the skin, can be an allergic reaction or caused by viral infections. Most hives can be treated at home with antihistamines, but severe reactions require medical attention.
It is important to identify and avoid triggers that may cause hives, such as certain foods, medications, or environmental factors. Keeping a diary of symptoms and potential triggers can help in determining the cause of hives.
If hives persist or recur frequently, it is recommended to see a healthcare provider for further evaluation and management. In some cases, allergy testing may be necessary to identify specific allergens causing the reaction.
Contact Allergy Rashes
Contact allergy rashes occur when the skin reacts to substances it comes in contact with. Identifying and avoiding the trigger is essential, and mild rashes can be treated with over-the-counter ointments.
Bacterial Rashes
Impetigo, a bacterial infection, can cause red, raw, and crusty skin. Over-the-counter antibiotics are useful for mild cases, but spreading rashes with fever require medical evaluation.
Rashes as a Medication Side Effect
If your child develops a rash from taking antibiotics, it is important to consult a doctor for assistance. Pay special attention if the rash appears on the lips, eyes, appears raw, or is bleeding.
Rashes can be a common side effect of many medications, not just antibiotics. It is important to monitor your child for any unusual skin changes while they are taking medication.
If your child experiences a rash along with other symptoms such as difficulty breathing, swelling of the face or throat, or severe dizziness, seek emergency medical help immediately as these could be signs of a severe allergic reaction.
In some cases, a rash may not appear immediately after starting a new medication. It could develop days or even weeks later. Keep track of when the rash started and any other symptoms your child may be experiencing to provide important information to the doctor.
Rashes Due to Viral Infections
Rashes can be caused by viral infections such as fifth disease or hand, foot, and mouth disease. It is advised to isolate the child with a rash to prevent spreading it to others. Monitor the rash to see if it goes away on its own.
If the rash persists, seek medical help for a proper diagnosis and to explore treatment options.
If your child develops an unexpected rash, take note of any other symptoms present to determine the appropriate course of action. Identifying the cause of the rash is crucial for planning the next steps.
Just a rash or something more?
Rashes could be a symptom of an underlying health issue. Assess the severity of the symptoms to determine the level of care required.
Viral skin rashes
Hand, foot and mouth disease
Hand, foot, and mouth disease can lead to the development of red spots and blisters. In most cases, it is mild and children can usually return to school within a few days.
Fifth disease
Fifth disease typically begins with red cheeks and spreads to the arms and thighs. The rash usually disappears on its own.
Roseola
Roseola is characterized by a fever and a fine pink rash. The rash tends to fade away within a few days without requiring treatment.
Chronic skin conditions
Eczema
Pediatric eczema can cause itching, especially in the joints. It is recommended to treat flare-ups with moisturizing creams and gentle soap.
Psoriasis
Psoriasis results in raised, red skin changes. The treatment for acne depends on its severity and may leave scars.
Environmental skin conditions
Sunburn
Ensure to protect your child’s skin with sunscreen when they are outdoors. Remember to reapply sunscreen regularly for adequate sun protection.
Keep infants out of direct sunlight and dress them in protective clothing.
Heat rash
It is essential for your child to stay hydrated and use sunscreen when playing outside in the sun. Heat rash is common in children under 1 year old and can result in small blisters forming on their skin due to sweating. Although not harmful, children can still become overheated or experience heat exhaustion. Dressing them appropriately for the weather and making sure they take breaks from the sun are important precautions to take.
“Babies are sensitive and vulnerable to dehydration and heat exhaustion,” states Dr. Torres-Zegarra.
Poison ivy, poison oak and poison sumac
Poison ivy, oak, and sumac are not frequently found in Colorado. However, being aware of the symptoms if your child gets a rash from these plants is beneficial. Parents may notice an itchy rash in streaks or lines on their child’s skin after contact with the plants, usually appearing a day or two later. This rash is not contagious and can last for weeks, sometimes requiring medical intervention. Remember the saying ‘leaves of three, let them be’ to avoid contact with these plants.
If your child develops a skin rash, seek advice and support from their pediatrician.
