NSSP Facility Participation by US County

Non-federal Emergency Care Participation in the National Syndromic Surveillance Program:
January 1, 2023, to April 1, 2024.

Dark blue counties contain at least one eligible non-federal emergency care facility that sent at least one valid patient visit record in the last three months. Light blue counties indicate the presence of one or more eligible emergency care facilities where no data have been sent to NSSP in the last three months. NSSP is working to increase participation in those areas. Gray counties do not contain eligible emergency care facilities.
