Roseola infantum, also known as exanthem subitum, is an acute febrile infectious disease caused by human herpesvirus type 6 or type 7. The main clinical manifestation is a sudden high fever that typically resolves after 3 to 5 days, followed by a rash. The rash, usually a skin rash, dissipates after about 2 days. If the child is breastfed, breastfeeding can continue. However, since it is a viral infection causing the fever and rash, the mother should consume a light and easily digestible diet to avoid burdening the baby's gastrointestinal tract. In addition, it is beneficial for the baby to drink plenty of warm water to aid in recovery from the illness.

Symptoms of roseola infantum

Roseola infantum, also known as baby measles, is caused by human herpesvirus infection, characterized by acute fever accompanied by a rash. Generally, there is no obvious trigger, and it begins with a sudden high fever, where the temperature can reach up to 39°C or even higher than 40°C. The high fever usually lasts for 3-5 days, during which some may experience fever-induced convulsions. Once the fever subsides, the rash begins to appear. Generally, the rash lasts for 1-2 days. After the rash subsides, and in the absence of complications, the condition resolves.

Do babies with roseola fear water?

Roseola infantum is a common pediatric rash disease caused by a viral infection. The main symptoms are a persistent high fever lasting 3 to 4 days, followed by a sudden drop in body temperature and the appearance of a rash. Roseola is caused by a viral infection and is not aggravated by water exposure. During the fever period, if the body temperature is below 38.5°C, it is acceptable to use a warm towel to wipe the child's forehead, neck, armpits, and groin to physically reduce the temperature. At the same time, it is important to ensure that the child drinks plenty of fluids. There is no relationship between roseola and water, and during the period of continuous high fever, it is crucial to keep the child hydrated, as a high fever causes significant fluid loss. Moreover, if the child does not receive adequate fluids, the fever may be difficult to reduce, which is an important point to note. Parents should understand that roseola is not exacerbated by exposure to water.

What should I do about baby rash?

Roseola infantum, also known as baby rose rash, is an acute contagious disease in children caused by viral infection. The characteristics of the disease include a sudden onset, with an initial fever lasting 3 to 5 days, followed by a rash after the fever subsides, usually resolving on its own. Roseola infantum is a self-limiting disease with a duration of about one week. Treatment does not shorten the recovery time but can help alleviate uncomfortable symptoms. Treatment measures include: 1. Rest and hydration – Encourage the child to rest and drink plenty of fluids. If the child is very uncomfortable or refuses to drink, hospital treatment may be necessary. 2. Fever management – If the child is very uncomfortable due to high fever, fever-reducing medication can be taken under a doctor's guidance, according to the child's weight.

How to determine baby rash?

Roseola infantum is a common acute exanthematous infectious disease in pediatrics, also known as baby roseola, caused by human herpesvirus types 6 and 7. To determine whether it is roseola, the main criteria are if the child is under two years old, especially infants aged 7 to 13 months, who exhibit a persistent high fever. During the fever, if the child’s fever subsides, they appear in good spirits and do not have other complications, then roseola should be highly suspected. In such cases, symptomatic treatment should be provided first, with a focus on hydration. If the temperature exceeds 38.5℃, give the child fever-reducing medication and continue to observe at home due to the persistent high fever, which lasts three to four days. Once the child’s temperature suddenly drops, carefully observe whether a rash appears on the trunk, neck, limbs, and facial area. If these symptoms are present, which match with the history of a high fever lasting three to four days followed by the appearance of a rash, the diagnosis is roseola infantum.
