-- Hurricane Matthew ripped through Haiti as a Category 4 storm with 145 mph winds on Tuesday, leaving villages flooded, roofs ripped from houses -- and a rising death roll. The country's Directorate for Civil Protection said Wednesday night the number of fatalities had doubled to 10.
Officials and observers say that some towns are almost completely destroyed and others have been cut off from communication, leaving loved ones to fear for the worst.
Mourad Wahba, the U.N. secretary general's deputy special representative for Haiti said in a statement that "Haiti is facing the largest humanitarian event witnessed since the earthquake six years ago," referring to an earthquake in 2010 that left some 200,000 people dead.
An NGO that operates in Haiti, the Haitian Health Foundation, shared a report with ABC News from a pilot that flew over the coastal Haitian city of Jeremie Wednesday.
The pilot said of Jeremie, "It's wiped out. Barely 1 percent of houses are standing. The people are alive ... they survived. But soon, they may starve. They're cutoff.”
The U.S. Military announced it is moving nine helicopters and 100 personnel to Haiti starting tomorrow to assist in the relief efforts.
He said there are some villages where they still haven't been able to hear from a single person.
Almazor added he is worried about Cholera and Zika outbreaks in Haiti, two major healthcare concerns that devastated the nation even before Matthew hit.
Partners in Health tweeted that is seeking donations, in advance of a "likely surge in Cholera."
"What would be the immediate need is to make sure that people get safe drinking water and safe water for washing," Almazor added.
In a statement this evening, Almazor said, “though the storm has passed, experience tells us that the worst is yet to come.”
