The titer of virus in the midgut is correlated with dissemination rate upon infection with YFV BA-55.

<p>Mean virus titers (log₁₀(PFU/ml)) in the midgut for each of the 8 collection sites were compared with the proportion of individuals in that collection that developed a disseminated infection using a Pearson correlation analysis. Mean viral titer in the midgut was correlated with the proportion of individuals that developed a DI upon infection with YFV BA-55(r = 0.843, P = 0.0086). There was no correlation in YFV DAK279 or DENV-2-75505.
