Overview
Rashes in babies and children are common and can appear as red spots, bumps, blisters, or patches on the skin. Most rashes are mild and self-limiting, but some may indicate serious infections or allergic reactions.
In Korea, pediatricians and dermatologists frequently evaluate rashes to identify their cause, which may range from viral or bacterial infections to allergic reactions or skin conditions like eczema. Early recognition ensures proper care and reduces complications.

What Are Rashes in Babies and Children?
A rash is a change in the skin’s color, texture, or appearance. In children, rashes can present as:
- Macules – flat, discolored spots
- Papules – small, raised bumps
- Vesicles or blisters – fluid-filled lesions
- Pustules – pus-filled bumps
- Plaques – raised, solid patches
Rashes may appear suddenly or gradually, be itchy or painless, and may be localized to certain areas or cover the whole body.
What Symptoms Are Related To
Rashes in children often come with other signs that help determine the cause:
➤ Fever or malaise – may indicate infection
➤ Itching or scratching – common in eczema or allergic reactions
➤ Swelling or redness – can indicate inflammation or infection
➤ Blisters or crusts – seen in chickenpox or impetigo
➤ Pain or tenderness – may suggest bacterial infection
➤ Respiratory or gastrointestinal symptoms – can accompany viral exanthems
