Surveillance Systems

Information on cases and outbreaks of enterovirus infection is collected in the United States using two surveillance systems:

  • National Respiratory and Enteric Virus Surveillance System (NREVSS): a voluntary, laboratory-based surveillance system that has included enterovirus reporting since July 2007. This system is used to track the number of enterovirus tests that are performed and the proportion that are positive, by specimen type, location, and when they were collected. Serotyping, demographic data, and clinical data are not reported.

  • National Enterovirus Surveillance System (NESS): a passive, voluntary, laboratory-based system that collects basic data on specimens positive for enterovirus or human parechovirus, including serotype. NESS has been collecting data since the 1960s.
