Rubella

Postnatal rubella is generally a mild illness that resolves spontaneously over several days to 1 week. The most important consequence of postnatal rubella infection is congenital rubella syndrome.

Arthritis

Arthralgias and arthritis may persist for weeks or months or recur, particularly in adult women. However, the overall prognosis for joint function is good.

Pregnant women

Maternal infection in nonimmune women during pregnancy, particularly early in gestation, may cause spontaneous abortion, fetal death, or a wide spectrum of anatomic and laboratory anomalies (congenital rubella syndrome).
