Petechiae of the soft palate or Florschheimer spots may be present. The diagnosis of rubella is clinical, although it may be confirmed by the demonstration of seroconversion in response to rubella antigens. Antibodies are often present shortly after the rash appears and increase in titer during the next 2-3 weeks. The presence of elevated IgM antibodies is particularly helpful in newborns. IgM antibodies do not cross the placenta and indicate a recent infection acquired post-partum.
Supportive therapy is all that is necessary.
Antipyretics - May be used to control temperature. Antihistamine - May be used to control itching. It is more effective in preventing histamine response than in reversing it. Arrange follow-up with the patient's primary physician. Beyond the fetal period, rubella is generally benign and self-limiting without complication.
