Hurricane Matthew killed more than 500 people in Haiti when it struck two weeks ago, leaving more than 175,000 without homes, and more than a million more struggling to survive in what United Nations Secretary-General Ban Ki-moon called “absolute devastation.” The UN estimates at least 1.4 million Haitians are now in need of urgent assistance as clean water, food, and medicine are in short supply, and an ongoing cholera epidemic threatens to worsen and spread after dozens of cholera treatment centers were destroyed.
