Question
After my child had a fever, many small red spots appeared on their skin, which seems to be roseola infantum. What are the characteristics of roseola infantum?
Answer
Roseola infantum, also known as “rose fever,” is a common rash disease in infants under 2 years old caused by a virus that enters the body through the respiratory tract. The virus incubates and then causes a fever. When the disease strikes, the infant will suddenly have a high fever, with temperatures reaching up to 39 to 40°C. Unlike other rash diseases such as measles and chickenpox, the characteristic of roseola infantum is its sudden onset and high fever, followed by the appearance of red spots on the skin, but it usually does not cause serious complications.
