The cholera outbreak ravaging Haiti is part of a worldwide pandemic that began 50 years ago and should be easy to stop — with technology developed in the 1800s.

Haiti’s poor sanitation system, however, makes it vulnerable to a disease that first swept the United States and other parts of the world more than 150 years ago. The current global wave of cholera — the seventh in recorded history — made its way from Asia to Africa then Latin America, and is now back for its second strike at this hemisphere.
