The United Nations has asked for 164 million US dollars (£102 million) to fight the cholera outbreak in Haiti that has already claimed 724 lives and is expected to continue spreading for up to a year.
The plea for funds was primarily made to donor nations, but also to international and regional organisations.
The cash will be used to bring in additional doctors, medicines and water-purification equipment to treat up to 200,000 people who could show cholera symptoms.
“We absolutely need this money as soon as possible,” said Elisabeth Byrs, a spokeswoman for the UN humanitarian office.
She added that the funds need to be provided quickly “otherwise all our efforts can be outrun by the epidemic”.
At least 11,125 cases of cholera have been confirmed in five of Haiti’s 10 districts since the outbreak began last month. Ten deaths and 278 cases have occurred in the capital Port-au-Prince.
And the World Health Organisation has warned that the epidemic is not likely to end soon.
“The projections of 200,000 cases over the next six to 12 months shows the amplitude of what could be expected,” said WHO spokesman Gregory Hartl, who also warned that the current fatality rate of 6.5% is far higher than it should be.
“No-one alive in Haiti has experienced cholera before so it’s a population which is very susceptible to the bacteria,” Mr Hartl said. “Once it is in water systems it transmits very easily, and it transmits among people who are often asymptomatic.”
He went on: “Cholera, now that it is in Haiti, probably the bacteria will be there for a number of years to come. It will not go away. The specific origin of this specific outbreak is something which probably will be investigated at some point, but what is important right now is the response on the ground.”
