Skin rash in children can have many causes, the most common include:
- Infection: viral, bacterial, or fungal.
- Eczema: a chronic skin condition that causes dryness, itching, and irritation.
- Allergic reaction to certain foods, medications, or chemicals.
- Heat rash caused by blocked sweat ducts.
- Friction rash from rubbing or chafing.
- Environmental factors such as inappropriate clothing or irritants.
Persistent or severe rashes may indicate a serious health problem such as measles. If your child has other symptoms like fever, consult the doctor immediately.
