Introduction
In general, after the rash of infantile急疹 appears, the following contraindications should be avoided: excessive skin cleansing, arbitrary application of medications, wearing thick or non-breathable clothing, consuming irritating foods, and frequent outings or exposure to large crowds. During the care process, parents should closely monitor the infant's skin condition and mental status, and maintain good indoor air circulation.

Generally, the contraindications after the rash appears in infantile emergency rash (roseola) include avoiding excessive skin cleansing, refraining from applying medications arbitrarily, avoiding overdressing or wearing non-breathable clothing, avoiding consumption of irritating foods, and avoiding frequent outings or contact with large crowds. The details are as follows:

1. Avoid excessive skin cleansing: During the rash period, an infant's skin is particularly sensitive. Excessive cleansing, such as frequent bathing or using strong cleansing products, may damage the skin's natural protective barrier, potentially causing dry skin, redness, or even worsening the discomfort associated with the rash.

2. Avoid applying medications arbitrarily: Some parents may apply ointments to infants on their own, but if the medication contains irritating hormones or chemical ingredients, it may irritate the skin, interfere with the normal resolution of the rash, or even cause skin allergies.

3. Avoid overdressing or wearing non-breathable clothing: Dressing infants in thick, non-breathable clothing after the rash appears may cause excessive heat and sweating, impairing normal skin respiration. This may prolong the duration of the rash and potentially worsen skin discomfort due to friction.

4. Avoid consuming irritating foods: For infants who have started complementary foods, irritating foods such as spicy, greasy, or allergenic items should be avoided during the rash period. These foods may increase the body's metabolic burden, potentially causing gastrointestinal discomfort or skin allergic reactions that interfere with recovery.

5. Avoid frequent outings or contact with large crowds: During the rash period, infants' immune systems have not fully recovered. Frequent outings or contact with many people increases the risk of exposure to external pathogens, which may lead to secondary infections, disease recurrence, or the development of other illnesses.

During care, parents should closely monitor the infant's skin condition and mental status, ensure good indoor air circulation, and create a comfortable environment to support the infant's skin and overall recovery to health.
