Exanthema subitum [sixth disease] due to human herpesvirus 6
ICD-10 B08.21 is a billable code used to indicate a diagnosis of exanthema subitum [sixth disease] due to human herpesvirus 6.
Exanthema subitum, commonly known as sixth disease, is a viral infection primarily affecting infants and young children, typically between the ages of 6 months and 2 years. It is caused by human herpesvirus 6 (HHV-6), which is a member of the herpesvirus family. The condition is characterized by a sudden high fever lasting 3 to 5 days, followed by a distinctive rash that appears as the fever subsides. The rash usually starts on the trunk and then spreads to the face and extremities, presenting as small, pink spots that may be slightly raised. While the fever can be quite high, the illness is generally self-limiting and resolves without complications. However, in some cases, febrile seizures may occur due to the rapid rise in temperature. Diagnosis is primarily clinical, based on the characteristic fever and rash pattern, and is often confirmed through serological testing for HHV-6. Treatment is supportive, focusing on fever management and hydration. Vaccination against HHV-6 is not currently available, making awareness and early recognition of the disease crucial for effective management.
