Nonpolio Enterovirus and Human Parechovirus Surveillance - United States, 2006-2008

VIEWS: 21 PAGES: 5

Villarruel presents a report that describes trends in nonpolio enterovirus and HPeV detections during 2006-2008, based on data from two laboratory-based surveillance systems, the National Enterovirus Surveillance System (NESS) and, for the first time, the National Respiratory and Enteric Virus Surveillance System (NREVSS). Enterovirus serotyping is performed by sequencing the genome region encoding the VP1 capsid protein by immunoflourescence using type-specific monoclonal antibodies, or by neutralization with type-specific polyclonal antisera. Since Jul 2009, a simplified, Internet-based NESS system has allowed participating laboratories to easily input enterovirus detection data and to analyze national and state-based trends in enterovirus surveilance, by serotype.
