Relationship between virus titer in non-human primate serum and transmission of (A) sylvatic dengue virus serotype 2 (DENV-2) or (B) sylvatic Zika virus (ZIKV) to Ae. albopictus (either body or leg infection). Curves fitted using a generalized additive model, allowing a variety of shapes, to unravel a possible pattern. Source data are provided as a Source Data file.
