Haiti has been hit by a cholera outbreak that is set to be far worse than health officials had thought.
Reports say rather than affecting a predicted 400 000 people; the diarrhoea disease could strike nearly twice as many.
Researchers at the University of California in San Francisco believe the toll will reach 800 000 with more than 11 000 deaths by the end of November this year.
Before last year’s devastating earthquake on the Caribbean Island, no cases of cholera had been seen on Haiti for more than a century.
Meanwhile the World Health Organisation says everything possible is being done to contain the disease.
