"Who knows the overall death toll?"
The United Nations said on Saturday that the government had confirmed 111,481 bodies had been collected following the 7.0 magnitude quake on January 12.
Meanwhile, the international aid agency leading efforts to provide shelter for the hundreds of thousands of survivors appealed for thousands more tents and and other forms of shelter.
The International Organisation for Migration (IOM) said in a statement that it had 10,000 family-sized tents in a warehouse in Port-au-Prince, but that "estimated needs stand at 100,000 to assist 500,000 persons".
Many of those made homeless by the quake are being resettled by Haitian authorities outside Port-au-Prince during reconstruction efforts.
Teresa Bo, Al Jazeeera's correspondent in Port-au-Prince, said people were taking advantage of the government's offer to take them by bus to the southwestern and northern parts of the country for free.
"Around 100,000 people have taken advantage of this. They are going to the southwestern part of the country away from Port-au-Prince where the situation is better.
"They are running away because they have nothing here, no food, no water, nothing."
Al Jazeera's Rob Reynolds, reporting from Saint Marc, a coastal city north of Port-au-Prince said: "We've seen school buses packed with people heading north, where the country was less affected by the earthquake.
"The total number of people in this urban exodus could be around a million people we're told."
Haiti's government estimated on Friday that around 609,000 people were without shelter in the Port-au-Prince area, according to the IOM.
Hundreds of Haitians gathered in the capital for a mass near the capital's Roman Catholic cathedral on Sunday, while others lined up to receive food packs, water and crackers from US and Brazilian tropps in Cite du Soleil, a Port-au-Prince slum.
Ken Keen, the US general leading the military's operations in the capital, said: "We are at the beginning of the massive effort to sustain providing food, water and medical assistance throughout the city.
"What we have been doing thus far is in a crisis reaction, obviously, to the situation, pushing out as much as we can to address the immediate needs, but we are entering a phase where have to be able to sustain it takes estimated one million rations a day in order to sustain it."
