Roseola infantum, also known as baby rose rash, is a viral infection primarily caused by human herpesvirus, leading to a feverish rash disease. The fever often begins suddenly without clear signs, potentially reaching high temperatures of 39 to 40 degrees Celsius. Typically, the fever lasts 3-5 days, after which the temperature might drop suddenly, possibly returning to normal within 24 hours. As the fever subsides, or shortly thereafter, maculopapular rashes appear, mainly on the face, neck, and trunk.

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.

Can infantile roseola recur?

Exanthem subitum (roseola infantum) is a common acute febrile rash disease in infants and young children, caused by human herpesvirus type 6 or 7. The main characteristic is that three to five days after the onset of fever, the fever suddenly drops, and rose-pink maculopapular rashes appear on the skin, easing the condition. If there are no complications, recovery is usually rapid. After contracting exanthem subitum once, most children acquire immunity and it is rare for them to experience it a second time. However, if a child has an immune deficiency or low immune function, there is still a possibility of contracting exanthem subitum again.

Can infantile roseola cause vomiting?

Roseola infantum is a common febrile exanthematous skin disease in infants and toddlers, primarily caused by viral infection. Its clinical presentation includes a sudden onset of high fever without obvious triggers in the child, with temperatures reaching up to 40 degrees Celsius. After 3-5 days of fever, the temperature suddenly drops, generally returning to normal within 24 hours. As the temperature decreases or after the fever subsides, a rash starts appearing. During the illness, the child often also experiences swelling of the lymph nodes behind the ears and neck, along with mild irritability, discomfort, and diarrhea. If vomiting occurs, it might indicate additional discomfort such as a gastrointestinal type of flu, potentially accompanied by symptoms like diarrhea and vomiting. If the child exhibits significant vomiting, along with other symptoms such as decreased urine output or diarrhea, it is advised to take the child to the hospital promptly for medical consultation and timely intervention treatment by a doctor.

What age do children typically get roseola?

Exanthem subitum in infants is a viral infectious disease caused by human herpesvirus type 6 and type 7. Newborns initially acquire protective antibodies from their mothers. Generally, after five to six months, as antibody levels decrease, the likelihood of contracting a virus such as human herpesvirus increases. The peak age for contracting exanthem subitum is between six months and two years, although this can vary. Children aged three to four, who have not contracted exanthem subitum or the human herpesvirus before the age of two, can still contract the disease.

Can children with roseola eat eggs?

Exanthema subitum, also known as roseola, is an acute febrile developmental disease caused by human herpesvirus type 6 or 7. Typically, the acute phase begins with a sudden high fever, where the body temperature can reach 39°C or even exceed 40°C, lasting for about three to five days. After the fever subsides, a rash appears, generally lasting about two days. In cases without complications, the rash disappears after two days, and the condition is resolved. During the fever phase, it is recommended to have a light diet with easily digestible food included. Eggs are rich in protein and phospholipids, making them a nutritious food option that can be given to children in moderation. However, excessive consumption may increase the burden on the child's gastrointestinal function and hinder digestion.
