Distribution of NoV sequences reported to the GenBank between 1976 and 2015 (n = 3134). a Nested pie chart of the NoV genotype distribution proportions. b Distribution of NoV sequences. All NoV sequences were grouped by year and divided into “All NoV”, “GI”, “GII”, “GII.3”, “GII.4” and “GII.17”. The solid line with symbol represents the percentages of “GII.3”, “GII.4” and “GII.17” for the years shown
