nssp county level map


Shown above are U.S. counties in which nonfederal emergency care facilities participate in the National Syndromic Surveillance Program (NSSP). Dark blue counties contain at least one eligible nonfederal emergency care facility that sent at least one valid patient visit record in the last twelve 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 twelve months. Gray counties do not contain eligible emergency care facilities.

Map Accuracy—NSSP has been informed that some data may be incomplete. We are looking into why this has occurred and will update the map soon. Meanwhile, if you have concerns or notice an anomaly, please submit a Service Desk ticket.external icon
