Can a baby go outside and be exposed to wind after the rash of roseola appears?

It is okay for a child with roseola to go outside after the rash appears, but exposure to wind should be avoided. During the rash phase, ensure the environment has clean and well-circulated air; windows may be opened appropriately for ventilation. Poor air circulation, overdressing leading to sweating, may increase the rash. On good weather days, moderate outdoor activities are beneficial—breathing fresh air helps regulate the child's immune system and promotes recovery. A child’s immune system is relatively weakened during the rash period, so extra care is needed to prevent catching a cold from exposure to wind. The rash may be accompanied by itching and discomfort, and wind exposure could trigger more rashes or worsen itching. It is recommended to avoid going outdoors and exposure to wind when the weather is poor or temperature fluctuations are significant. Seek medical attention promptly if any discomfort occurs.
