Rubella is a virus that causes an infection that is usually mild and characterized by fever and rash that last about 2 to 3 days. The Infection is highly contagious but is preventable with a vaccine. A rubella test detects and measures rubella antibodies in the blood that are produced by the body's immune systemRubella. Rubella is caused by a virus that is spread through the air or by close contact. A person with rubella may spread the disease to others from 1 week before the rash begins, until 1 to 2 weeks after the rash disappears. Because the measlesmumpsrubella (MMR) vaccine is given to most children, rubella is much less common now. rubella virus immune system

The disease is caused by rubella virus, a togavirus that is enveloped and has a singlestranded RNA genome. The virus is transmitted by the respiratory route and replicates in the nasopharynx and lymph nodes. The virus is found in the blood 5 to 7 days after infection and spreads throughout the body.

Studies suggest that vaccinated individuals having these low levels of antirubella IgG do show a secondary immune response following revaccination but have not been challenged with wild rubella virus. A followup sample should be taken to further evaluate immune status. Immune Response. Capable of crossing the placenta, rubella is attenuated only by the maternal IgG present in the fetus' blood. Because the level of the immunity is so low in the first trimester fetus, the virus is usually able to set up a succesful infection, resulting in extreme pathogenesis. rubella virus immune system Immune Globulin IV, IVIG, IGIV: (Major) Rubella virus vaccine or Measlesmumpsrubella vaccines, MMR should not be given for at least 3 months following administration of blood, plasma, andor immunoglobulins because antibodies in these products can neutralize the vaccine.

An assay capable of distinguishing between the immune response generated by recent exposure to rubella virus and the immune response existing as a result of past exposure or immunization is required for the diagnosis of primary rubella virus infection, especially in pregnant women.
