Figure A1. Monthly distribution of cDNA viral load of norovirus (NoV) genogroup I (GI) and GII during the study period (December 2004 through November 2005). In the scatterplot, cDNA viral loads of NoV GI and GII are represented by open and solid squares, respectively. Lowess fit lines for the seasonal variation of the cDNA viral loads of NoV GI and GII are represented by dashed and solid lines, respectively. Local monthly mean air temperature (temp.) is tabulated.
