Answer is : E Roseola infantum, also known as exanthem subitum, is a disease caused by the human herpesvirus 6 that primarily affects infants and young children. It is characterized by a 3-day high fever (causing a tonic-clonic febrile seizure in this child) that ends abruptly (“3-day fever”) and is immediately followed by a blanching, maculopapular, nonpruritic rash. The rash appears mainly on the trunk but may spread to the face and extremities. It is commonly associated with cervical, postauricular, and/or occipital lymphadenopathy. Treatment is symptomatic as the disease is self-limiting.
