TORCH information, Rubella

Rubella

Rubella is a virus that has a seasonal pattern, with epidemics most likely in the spring. Between 0.1 to 2 percent of newborns are infected with rubella. The rate of fetal infection varies according to the timing of the mother's infection during pregnancy. Birth defects, however, are most likely (85%) in infants infected during the first eight weeks of pregnancy. Infants born with rubella may already show signs of heart disease, retarded growth, hearing loss, blood disorders, vision problems, or pneumonia. They may also develop problems later in childhood, including autism, hearing loss, brain syndromes, immune system disorders, or thyroid disease.
