Clinical Significance
Acute rubella viral infection is usually a mild, self limited, benign disease of short duration with symptoms that include low grade fever and a rash. However infection of the fetus during the first trimester of pregnancy may result in severe congenital abnormalities (congenital rubella syndrome). IgM antibodies to the virus appear and decrease rapidly within 4 to 5 weeks after the onset of symptoms, but IgG antibodies usually persist for life. Rubella tests may be used to define immune status and to determine the need for vaccination, to evaluate vaccine efficacy and as an aid to the diagnosis of recent infection. The patient groups normally tested are women of childbearing age, pregnant women or healthcare workers who may have close contact with a confirmed rubella case or have the clinical indicators of rubella viral infection.
