Survey: 30% of Toddlers Progress to Impetigo Due to Improper Care for Heat Rash

## Survey Overview
IC Clinic, operated by the medical corporation Tetsu-Ketsu-Kai, conducted an internet survey of 300 parents with children aged 0 to 6 to understand skin troubles during the rainy season. The survey period was from May 18 to May 27, 2026.

## Key Findings
89.4% of parents have experienced heat rash (prickly heat) in their children. Notably, 31.7% reported that they worsened the condition into a bacterial infection such as impetigo due to incorrect care.

While many parents initially turn to over-the-counter ointments (41.3%), only 12.3% seek dermatological care as a first step. Medical experts strongly recommend visiting a dermatologist if symptoms do not improve within three days.

## Glossary
- **Heat Rash (Prickly Heat)**: A skin condition caused by blocked sweat ducts. Mild cases resolve in cool environments.
- **Impetigo**: A bacterial infection stemming from open wounds such as heat rash or insect bites. Requires antibiotic treatment.
- **Sweat Duct Obstruction**: Clogging of sweat ducts, which infants are particularly prone to.

## Criteria for Home Care vs. Dermatological Visit
- **Home Care**: Applicable if the rash is limited to specific areas (neck, back), involves only redness/tiny bumps, and improves in a cool environment.
- **Dermatological Visit**: Recommended if the rash spreads, involves blisters, pus, or oozing, or does not improve after three days.
