Confirmed congenital rubella syndrome cases, including those confirmed clinically, epidemiologically, or by laboratory investigation. Cases that have been discarded following laboratory investigation should not be included. Congenital rubella syndrome (CRS) is an illness in infants that results from maternal infection with rubella virus during pregnancy. When rubella infection occurs during early pregnancy, serious consequences–such as miscarriages, stillbirths, and a constellation of severe birth defects in infants–can result.
