Abstract
The importance of spatial heterogeneity and spatial scales (at a village
or neighbourhood scale) has been explored with individual-based models.
Our reasoning is based on the Chilean Easter Island (EI) case, where a
first dengue epidemic occurred in 2002 among the relatively small
population localized in one village. Even in this simple situation, the
real epidemic is not consistent with homogeneous models. Conversely, including contact heterogeneity on different scales (intra-households, inter-house, inter-areas) allows the recovery of not only the El
epidemiological curve but also the qualitative patterns of Brazilian
urban dengue epidemic in more complex situations.
