About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Notifiable Diseases Surveillance System
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
Target-Setting Method: 
Total elimination
Target-Setting Method Justification: 
Endemic transmission of rubella was declared eliminated from the United States in 2004. In 2007 and 2008, a total of 9 and 13 U.S.-acquired rubella cases were reported in the United States, respectively. The Pan American Health Organization (PAHO) developed a comprehensive strategy in 2004 to eliminate rubella and CRS from the Americas by 2010. Countries have demonstrated progress toward the rubella and CRS elimination goal. Until rubella is eliminated from the Americas and other countries, rubella cases and possibly CRS cases will be likely in the United States. Subject matter experts have given the continued risk of rubella transmission in the United States consideration in setting the HP2020 target.
