Roseola infantum is a common febrile rash disease in toddlers, primarily affecting infants under three years of age, with the general peak incidence at six to seven months. It is usually caused by a viral infection. During the period of roseola, the baby's immune system is weak. Exposure to drafts can lead to catching a cold and may coincide with other viral and bacterial infections, potentially causing discomfort such as coughing, nasal congestion, runny nose, vomiting, diarrhea, etc. Therefore, during the period of roseola, try to avoid taking the baby to crowded places or drafts, or going out in cold weather, and pay attention to caregiving. When their immunity is weak, avoid exposure to cold. Thus, it is best to keep the baby from being exposed to drafts during roseola.
