A “surge” in the number of new cholera cases in Haiti has created the risk of a humanitarian crisis, the UN expert in charge of fighting the disease said Thursday.

Assistant Secretary-General and Senior Coordinator for Cholera Response in Haiti Pedro Medrano Rojas said that the last three months have seen more than 12,000 new cases of the disease and that the struggling Caribbean country is on course for 50,000 cases this year.

Mr Rojas called for help from the international community, telling Daniel Johnson that Haiti will continue to need outside help for many years after the devastating 2010 earthquake.
