The cholera epidemic in Haiti will be a year old in October and is far from under control. As cases spiked across the country during the summer rainy season, the ranks of cholera relief workers grew thin. Too few patients reach healthcare facilities with enough time to be sure that treatment—simple rehydration in most cases—can restore them to health. Access to clean water and to modern sanitation is dwindling. We must redouble existing efforts at cholera prevention and care—case-finding and treatment, water and sanitation projects, education and surveillance—while simultaneously integrating vaccination into the ongoing response. Even prior to this epidemic it was clear that waterborne pathogens posed great risks to communities across the country, including those not affected directly by the January 2010 earthquake. All steps to protect Haiti’s vulnerable population needed, and still need, to be taken.
