The rash may be pruritic, but it usually resolves within 3 days without residua. The rash consists of pink macules and papules, which may become confluent, resulting in a scarlatiniform eruption. Petechiae of the soft palate or the Forchheimer sign may be present. Antibodies are often present shortly after the rash appears and increase in titer during the next 2-3 weeks. IgM antibodies do not cross the placenta and indicate a recent infection acquired postpartum.
Supportive therapy is all that is necessary.
Antipyretics - May be used to control temperature. Antihistamine - May be used to control itching. More effective in preventing histamine response than in reversing it. Arrange follow-up care with the patient's primary physician. Beyond the fetal period, rubella is generally benign and self-limiting without complication.
