As this is a generally mild disease in children, the primary medical danger of rubella is the infection of pregnant women, which may cause congenital rubella syndrome in developing babies. In most cases, symptoms appear within 16 to 18 days.Diagnosis is by blood test or virus culture.Anyone can get rubella, but unvaccinated, school-aged children are most at risk. Most cases of rubella are mild. About half of people infected with rubella virus get a rash that looks like small, fine pink spots. The rash first appears on the face and progresses from head to foot, lasting about 3 days. Children usually develop few or no other symptoms. Adults can have mild fever, headache, reddened eyes, swollen glands behind the ears, tiredness, and joint pain.
