The U.S. National Authority for Containment of Poliovirus (NAC), located at the Centers for Disease Control and Prevention (CDC) Center for Preparedness and Response, is seeking water utility participation in a survey about poliovirus containment. The survey should be completed by laboratories, storage sites, or other facility types that test, extract, handle or store biological samples from humans, experimentally infected animals, sewage or environmental waters. The survey questions are intended to identify facilities that possess any materials that could potentially contain poliovirus. The survey can be accessed on NAC’s website . In compliance with the World Health Organization Global Action Plan ( GAP III ), the U.S. is required to complete a national inventory of poliovirus-containing materials by surveying laboratories and other facilities. An initial survey was released in 2015 to identify facilities with infectious poliovirus materials and potentially infectious stool specimens. The survey responses were used to identify candidate poliovirus-essential facilities for containment certification. For additional information or questions, contact NAC at 404-718-5160.
