Norovirus Genotype Profiles Associated with Foodborne Transmission, 1999–2012
|FBVE/Noronet, n = 1,715||ESR-EpiSurv, –n = 584||CaliciNet, –n = 3,094||Systematic literature review, n = 8||Global profile, –n = 5,393|
|GII.4||0.07 (0.06–0.09)||0.09 (0.06–0.11)||0.12 (0.10–0.14)||0.12 (0.00–0.40)||0.10 (0.09–0.11)|
|Other genotypes||0.31 (0.25–0.37)||0.25 (0.17–0.33)||0.26 (0.23–0.30)||0.67 (0.16–0.97)||0.27 (0.25–0.30)|
|Mixed outbreaks||0.75 (0.48–0.94)||0.50 (0.20–0.75)||0.16 (0.05–0.33)||CNBC||0.37 (0.24–0.52)|
*FBVE/Noronet polymerase profile was used to compare with ESR-EpiSurv polymerase, systematic literature review polymerase, and CaliciNet capsid profiles. CNBC, could not be calculated; ESR, Institute of Environmental Science and Research; FBVE, Foodborne Viruses in Europe. Estimates in italics do not statistically differ from the FBVE/Noronet polymerase profile as a reference; estimates in boldface do statistically differ. †Proportion of outbreaks with an unknown mode of transmission estimated to be attributed to food.
