FOOD SAFETY Further Testing of Norovirus Negative Outbreaks September 2013 – June 2018 (n = 244) norovirus-negative specimens. Of those 244 specimens, 18% were positive for sapovirus, 10% were positive for rotavirus and 3% were positive for astrovirus (Figure 1). 3 The additional testing performed by CDC and the UVD sites provides valuable information on norovirus-negative outbreaks that would otherwise be classified as outbreaks of undetermined etiology. Jurisdictions with norovirus- negative outbreaks can send specimens to any of the UVD sites for additional testing at no charge. UVD sites need at least three patient samples per outbreak along with basic epidemiologic information including outbreak date or onset date and jurisdiction. For additional information on UVD testing and specific site contacts, please contact CDC CaliciNet staff at calicinet1@cdc.gov. n Viral Negative Outbreaks 69% Viral Positive Outbreaks 31% Sapovirus 18% Rotavirus 10% Astrovirus 3% Mixed <1% Figure 1.
