TURNING THE TIDE AGAINST CHOLERA: “A treatment protocol so effective that it saves 99.9 percent of all victims was pioneered here. The World Health Organization estimates that it has saved about 50 million lives in the past four decades. Just as important, after 35 years of work, researchers in Bangladesh and elsewhere have developed an effective cholera vaccine. It has been accepted by the W.H.O. and stockpiled for epidemics like the one that struck Haiti in 2010. Soon, there may be enough to begin routine vaccination in countries where the disease has a permanent foothold.”
