Protests over the cholera epidemic faded Friday but young men burned tires and threw rocks at police near government buildings amid surging anger over a disease that has killed more than 1,100 people so far.
Frustrations simmered as the medical aid group Doctors Without Borders issued a statement that "despite the huge presence of international organizations in Haiti, the cholera response has to date been inadequate in meeting the needs of the population."
The aid group, which has been one of the primary responders to the epidemic, said that other international organizations have failed to provide enough safe water or soap, build enough latrines and waste disposal sites, or remove dead bodies. It also criticized groups for not reassuring people that the disease is treatable.
Cholera had never before been confirmed in Haiti, and fears spurred by the arrival of the disease have led to attacks on treatment facilities and riots against U.N. peacekeepers who many suspect of having brought the disease to Haiti.
Friday's small-scale protest in the capital, Port-au-Prince, was far more muted than those of the day before, when demonstrators' attacked foreigners' cars. In the northern city of Cap-Haitien, the country's second-largest, several days of protests left three people dead and virtually shut off medical aid to cholera sufferers there.
It was quiet in Cap-Haitien on Friday: Local authorities cleared road barricades, allowing medical aid to flow back into the city, while relatives of cholera victims carried coffins. An Associated Press cameraman saw several corpses lying on the streets.
The area has the highest fatality rate in the country, with 7.5 percent of people who are hospitalized succumbing to the infection.
U.N. humanitarian agencies had appealed for a halt to the demonstrations, saying that lives were being lost because they could not reach people who needed care.
The upheaval over the cholera outbreak that has killed comes just days before national elections planned for Nov. 28. U.N. officials argue that the violence is being encouraged by forces that want to disrupt the ballot, and some demonstrators Thursday threw rocks at an office of President Rene Preval's Unity party and tore down campaign posters.
But the anger is fueled by suspicions that a contingent of Nepalese soldiers brought cholera with them to Haiti and spread the disease from their rural base into the Artibonite River system, where the initial outbreak was centered last month. It is a suspicion shared by some prominent global health experts.
Cholera had not been recorded before in Haiti despite rampant bad sanitation and poor access to drinking water, problems that cause outbreaks of the disease in other parts of the world. Cholera is endemic to Nepal and there was an upsurge there before the Nepalese troops came to Haiti.
The disease had spread to Haiti's national prison in Port-au-Prince, International Red Cross spokesman Marcal Izard said Friday in Geneva.
Izard said 30 inmates have been infected with the diarrheal disease and 10 have died in the past four days. The prison holds 2,000 inmates, or about a quarter of Haiti's total prison population.
The disease is spread by contaminated fecal matter. Health experts say it can be easily treated with rehydration or prevented outright by ensuring good sanitation and getting people to drink only purified water.
But after years of instability, and despite decades of development projects, many Haitians have little access to clean water, toilets or health care.
