Timing and persistence of dengue epidemics across geographic regions in Peru. A) The average annual timing profile of dengue outbreaks in jungle, mountain and coastal regions obtained from the average of the scaled dengue epidemics at the province level; B) Epidemic peak timing as a function of the longitude coordinates of provinces across jungle (green circles), mountain (red crosses) and coastal (blue squares) regions in Perú. The peak timing of dengue epidemics is significantly correlated with the longitude coordinate of the provinces (Spearman rho = -0.42, P = 0.0023).
