The U.S. military helped deliver food and medical help Monday, and the U.S. Agency for International Development donated $10 million.
Money also trickled in from around the world:
The European Union gave $2.85 million for relief efforts, and the Dominican Republic -- also struck by some of this year's storms -- donated water, food and mattresses.
Trinidad and Tobago sent Haiti about $1.5 million.
Two U.S. Navy MH-53 Sea Stallion helicopters flew tens of thousands of pounds of food to Jeremie, an isolated Haitian city that Hurricane Gustav pounded.
And the USS Kearsarge, a Navy hospital ship equipped with four operating rooms and 53 beds, arrived in Port-au-Prince after being rerouted from a mission to Colombia.
''It gives us a purpose,'' said Sugat Patel, 34, an infectious-disease physician aboard the Kearsarge.
He had five days off ahead of him until the ship was sent to Haiti.
``I believe every soldier here would rather be doing something like this. They are doing their job.''
In South Florida, meanwhile, politicians, charities and Caribbean-American coalitions called on people to send cash and supplies to the region.
''Despite our economic downturn in Florida, we must make a generous sacrifice,'' Miami Archbishop John C. Favalora said.
Favalora assured that the money would be delivered directly to churches in Haiti, Cuba, the Dominican Republic, the Bahamas, Jamaica and other affected countries.
He then waded into the contentious political debate surrounding U.S. policy toward Cuba and Haiti, calling for an immediate granting of temporary protected status for Haitians.
That status would stop deportations of Haitians, which Favalora said would be unspeakably cruel given the current conditions on the island.
South Florida congressional representatives also urged President Bush to halt the deportation of illegal Haitian immigrants until the island recovers from Ike's devastation.
And a coalition of Cuban-American groups asked the Bush administration to temporarily lift the sanctions on family aid and remittances, as did Democratic presidential candidate Barack Obama.
