Cholera continued to spread throughout devastated parts of Haiti as officials estimated at least 1,000 people were killed by Hurricane Matthew.
In some parts of the country, cases of the waterborne disease have risen dramatically since last Tuesday's storm - with numbers expected to rise.
Officials have cited the immediate death toll from Matthew, a Category 4 hurricane which mainly hit west Haiti, as standing at at least 1,000.
More than 1.3 million people were affected by the storm while over 60,000 were forced to evacuate.
An estimated 750,000 people are now in need of assistance, according to the UN Office for the Coordination of Humanitarian Affairs.
Matthew - which was a category 5 storm when it hit Haiti last week killing nearly 900 people - made landfall in the States on Friday.
As Hurricane Matthew approaches Florida, its 140-mile-an-hour winds have already left behind a trail of destruction in Haiti.
Residents told to fully prepare for the arrival of the hurricane with warnings its impact could be "devastating".
