Roseola infantum commonly occurs in infants under one year old, caused by human herpesvirus type 6 infection. It typically presents with very high fever, with temperatures often reaching 39-40 degrees Celsius, and throat congestion. However, the patient generally remains in good condition without obvious symptoms of infection or poisoning. Blood tests are generally normal, indicating a viral infection. Symptomatic treatment is given, and about three to five days later, the temperature abruptly drops. One to two days after the temperature returns to normal, a red, rose-like rash appears, primarily on the head, face, and trunk, consistent with the clinical manifestations of rash following the resolution of the fever.

Should children with roseola avoid certain foods?

Roseola in infants is an acute febrile and rash disease, caused by human herpesvirus type 6 or 7. The fever usually lasts 3-5 days, with high fever as the main symptom. During this period, infants may also experience other symptoms such as decreased appetite, vomiting, or diarrhea, which can affect the function of the digestive system, leading to indigestion. It is recommended that the diet be light and easy to digest, avoiding spicy, stimulating, and greasy foods, as these are not conducive to digestion nor beneficial for recovery from the illness.

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.

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.

What to do with baby's sudden rash?

If a child develops sudden exanthema, parents need not be overly worried, as this condition is a rash-causing disease due to herpes virus infection and it can heal on its own. Often, the child may experience high fever for three to five days, during which physical cooling techniques and oral antipyretics can be used for symptomatic treatment. It is also appropriate to ensure the child drinks plenty of water and eats nutritious food. Once the fever symptoms alleviate, scattered rose-like rashes may appear on the child's face and trunk, which can fade on their own. During this period, symptoms of indigestion or itchy skin may occur, and taking calamine for itch relief and oral probiotics can help alleviate symptoms of digestive upset. (The use of medications should be conducted under the guidance of a physician.)
