In cooperation with research groups at EPFL (Lausanne, CH) and Princeton University, the Ecology group at DEI proposed a model just appeared in Geophysical Research Letters (2011, vol. 38, L06403) for the prediction and control of cholera outbreak in Haiti. The control strategy that appears most effective to weaken the strength of the residual evolution of the infection is targeted sanitation. In contrast, mass vaccination would have a negligible impact at this stage of the epidemic. Other two models have been published this month in prestigious medical journals (including The Lancet) by Canadian researchers and a group at the Harvard Medical School. However, compared to newly available data, the predictions of the DEI model are much more reliable, week after week. The full paper is attached.
