Exanthem subitum, often known as roseola, is a medical condition.
Infections caused by the primary human herpesvirus-6 (HHV-6) and HHV-7 result in a condition known as exanthema subitum (roseola infantum). This condition is marked by a high fever in a healthy infant, which lasts for three days and is then followed by a sudden appearance of a rash.
The newborn experiences a prodrome characterized by a continuously high fever ranging from 38.9°–40.6°C, with temporary relief in the morning. This fever persists until the fourth day when it abruptly returns to normal, coinciding with the emergence of a rash.
Abnormalities
The exanthema is characterized by tiny, pink macules and papules on the neck and trunk. These lesions are 1-5 mm in diameter and can either remain separate or merge together. Anatomical distribution: mostly located in the trunk and neck regions.
The diagnosis is typically established based on clinical observations.
Exanthem subitum is a condition that often resolves on its own without the need for treatment, and complications are uncommon.
Antivirals should be administered to patients with weakened immune systems.
