What is the WTC Health Registry?
The Registry was developed to document and evaluate the long-term physical and mental health effects of 9/11. Enrollment was open from September 2003 through November 2004. More than 71,000 people enrolled by completing a 20 to 30 minute telephone interview. This made the Registry the largest effort in the U.S. to monitor the health of people exposed to a large-scale disaster.
