Hundreds have died and at least 1.4 million people need assistance
The United Nations has said it urgently needs more than €100m as part of a 'massive response' to help Haiti.
UN Secretary-General Ban Ki-moon announced the launch to fund aid activities in the aftermath of Hurricane Matthew.
The storm made landfall in Haiti on October 4th and went on to leave a swath of devastation throughout the Caribbean.
Hundreds have died and at least 1.4 million people need assistance.
It is feared the rising death toll, coupled with the start of the rainy season, will lead to waterborne diseases.
The UN Children’s Fund (UNICEF) is concerned for children living in the worst-affected areas.
The so-called flash appeal, launched by the UN on behalf of the international humanitarian community, requests US$119,850 (€107,750) to respond to "the most urgent needs" of people impacted by the storm.
According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), the appeal targets vulnerable groups in identified priority sectors, and it takes into account the national-level capacities and those of humanitarian partners on the ground.
Over the next week, the UN says partners will develop individual projects in support of sector activities and financial requirements identified in the appeal, adapting the response to the most up-to-date assessment results.
In a statement, UN Emergency Relief Coordinator Stephen O'Brien stressed that funding of the appeal is urgently needed to enable humanitarian actors to respond to people most in need before the situation further deteriorates - including by addressing the risks posed by cholera and other deadly waterborne diseases.
"Families that were fortunate to survive the hurricane now find themselves in a struggle to survive, with thousands of homes and livelihoods washed away by the storm," he said.
Speaking at UN Headquarters, Mr Ban explained that some towns have been almost wiped off the map as a result of the storm.
The chairman of Digicel Haiti, Maarten Boute, will be speaking about the impact of Hurricane Matthew in an interview on Newstalk Breakfast tomorrow.
