Since the researchers' model is able to differentiate between the two major avenues of cholera transmissionby surface water and by infected individualsthey are able to assess how interventions that target these two mechanisms might be used to stem the progression of the disease. The authors argue that at this stage of the epidemic, emphasis should be placed on ensuring clean food and drinking water rather than pursuing less effective vaccination campaigns. The authors suggest that reducing in 1 month the exposure to contaminated food and water by 40 percent could severely limit the perpetuation of the epidemic.
