In Haiti the cholera epidemic is growing. Official figures show the number who have died from the disease has risen above 300.
Haiti’s health ministry said it was spreading too, with confirmed cases in two new provinces in the north and north east.
And with 1.3 million people living in makeshift camps following Haiti’s devastating earthquake in January, it is hard to contain.
Nevertheless, a senior UN official said the major international reaction to the outbreak was encouraging.
The UN Humanitarian Co-ordinator in Haiti, Nigel Fisher said: “I am satisfied with the first week’s response because we are beginning to see a decrease in the number of deaths among those who have been hospitalized.”
For the 12,000 UN troops in Haiti the epidemic is making their peacekeeping task more difficult, with the ever present threat of violence in the run-up to presidential elections.
In St Marc, a treatment centre set up by the French charity Medecins Sans Frontieres was attacked by people fearful that it would spread the disease to nearby schools.
