AU-PRINCE: Aid groups fought Thursday to halt the spread of cholera in Haiti's teeming capital, where makeshift camps crammed with earthquake survivors are ripe ground for the epidemic to take hold. The outbreak erupted in the Artibonite River valley in central Haiti in mid-October and initially seemed to have been contained, but the toll from the chronic diarrheal disease has since soared to 643 dead and just under 10,000 people being treated in hospital. Some 115 cases and a first death have been confirmed in Port-au-Prince, while reports came in from northern Haiti of villagers on foot dying on the way to hospital and taxi drivers too scared to help. Most of the estimated 1.3 million Haitians living in refugee camps are in tent cities around the capital and water-borne cholera could spread easily in the unsanitary conditions where supplies are shared for cooking and washing. “The epidemic of cholera, a highly contagious disease, is no longer a simple emergency, it's now a matter of national security,” the director of the Haiti's health ministry, Gabriel Thimote, told a press conference Tuesday. Haitian authorities have been warned to prepare for the worst if cholera spreads in the capital, which is still largely in ruins after a January earthquake that killed more than 250,000 people. “Port-au-Prince is a large urban slum with very poor water and sanitation conditions. This is ripe for the rapid spread of cholera. We have to be prepared for it,” said top UN health official Jon Andrus. Leading humanitarian organization Doctors Without Borders (MSF) said it was extremely concerned at the increase in the number of patients with cholera-like symptoms in the capital. “The increasing numbers of cases of suspected cholera in our facilities throughout Port-au-Prince are certainly alarming,” said Stefano Zannini, MSF head of mission in Haiti. MSF, which runs the Saint Catherine's Hospital in the Cite Soleil slum where the capital's first cholera fatality was confirmed, said it was constructing an additional 320-bed facility in the city's Sarthe neighborhood. Oxfam said it had a team of 25 staff working around the clock with a water, hygiene and sanitation program reaching about 100,000 people to distribute soap, water purification tablets, buckets and rehydration salts. “It is a very serious development that cholera has spread in Port-au-Prince,” the organization said in a statement. “However, it is understandable. With heavy rains and flooding over the weekend, in an environment where there is poor sanitation, waterborne diseases like cholera spread very rapidly.” – Agence France
