Disease models of rift valley fever
WebThe Rift Valley Fever (RVF) is a viral zoonosis (disease transmitted from animals to humans) that primarily affects animals, but also has the capacity to infect humans. Infection can cause severe disease and death in both animals and humans. To estimate the remaining parameters θ of the model (Supplementary Table 4), we fitted the metapopulation model to the serological data in a Bayesian framework. Below, we define the observation model (likelihood) and priors of each parameter that were used to fit our model to the livestock seroprevalence … See more The Comoros archipelago is a group of four islands—Grande Comore (1146 km2), Mohéli (290 km2), Anjouan (424 km2) and Mayotte (374 km2)—located in the northern part of the … See more The parameters of the model were selected based on the current knowledge on RVF epidemiology and demography of the livestock population in the Comoros archipelago.
