Cholera has been confirmed as the deadly disease spreading across central parts of Haiti. It's the first outbreak there for more than a century. One hundred and forty people have died so far. James Read reports.

President Rene Preval said tests had confirmed what everyone feared. The deadly illness spreading through central Haiti is cholera. The outbreak has been blamed on the Artibonite river, which is the main source of water for thousands of people. One aid worker described scenes of chaos in the town of Saint-Marc, with patients laid out in array in a hospital courtyard and people with buckets begging for clean water on the side of the road.
