  Figure 1. Age profiles of 52 sapovirus-positive children with and without co-infection. “Three or more viruses” corresponding to sapovirus co-infection with two from one of the following viruses: rotavirus A, norovirus, human bocavirus, and human adenovirus. Numbers within each bar of the graph correspond to the “n” of children.

  Figure 2. Map of Roraima state (the state of Amazonas and countries of Venezuela and Guyana are indicated outside this map), where the sapovirus genotypes are indicated according to the subtitles. Behind the map of Roraima, the map of Brazil is shown, where the state of Roraima is indicated by a blue dotted arrow (https://www.google.com/maps/place/Brazil/; accessed on 26 July 2021).

  Figure 3. Phylogenetic tree of sapovirus based on partial capsid VP1 gene sequences from children from the Amazon region. Sequences were analyzed using the maximum likelihood method (Tamura–Nei model), and bootstrap values >80% are shown at the nodes of the tree as percentages on 2000 replicates. The strains reported in this study are indicated by circles. The reference strains are shown with their respective GenBank access numbers and each genotype outside of brackets.
