Who is at Highest Risk for Complications from Rubella?
For most people, rubella is a mild, self-limiting illness; however, a woman who develops rubella during the first three months of pregnancy has a greater chance of miscarriage and of giving birth to a baby with congenital rubella syndrome (CRS) and birth defects.1
Infants with CRS can have multiple health issues affecting nearly all organs of the body, including deafness, vision impairments, cardiac defects, microcephaly, neurological abnormalities, developmental delays, and more.2 Up to 85 percent of infants exposed to rubella in the first eight weeks of fetal development are at risk for CRS. By 12 weeks, the risk decreases to 50 percent and by 20 weeks, the risk is essentially zero.3
In 2018, there were four reported cases of rubella in the U.S. and between 2009 and 2017, there were an average of five rubella cases per year. There were no reported cases of CRS in the U.S. in 2018.4 5
