The cholera outbreak in Haiti continues to spread and the death toll is rising. Rev. Franklin Graham has asked the U.S. government to airlift rehydration fluids to combat the epidemic.

Graham, the top executive of Samaritan's Purse, said tens of thousands of people could die unless the necessary supplies arrive quickly.

In Haiti, ordinary vans have been converted into giant hearses. Morgues are overflowing and authorities said finding places to bury the dead is becoming a challenge.

"We have had long discussions with counterparts and mayors," said Nigel Fisher, United Nations humanitarian coordinator. "Where can we bury people who have died from cholera? And mayors are reluctant to have them in their communities, people protest."

The problem? Even after cholera kills its host, the bacteria lives on. As a result, those who die are disinfected and zipped into the white bodybags. The dead are trucked to the countryside and buried in mass graves.

One worker said he was paid $40 to dig five graves -- as much as most people make in the island nation in a week. The man said he expects much more work to come.

Already, cholera has claimed more than 1,400 lives in Haiti, and has sickened an estimated 60,000.
