The International Monetary Fund (IMF) has called for a $1.5bn funding boost to the UN health agency for Sierra Leone, which is battling a deadly outbreak.
The World Health Organisation (WHO) is also struggling to cope with a record number of new cases and deaths, as well as an acute shortage of beds and medicine.
The agency is also facing an acute funding shortage as the number of people in need of treatment across Sierra Leone is expected to increase significantly.
According to the International Organisation for Migration (IOM), there are currently 3,500 people in Sierra Leone waiting to be admitted to hospital for treatment, with the number expected to grow as the epidemic progresses.
According the IOM, around 1,500 new cases of Ebola have been recorded since the start of the year, bringing the total to more than 15,000.
More than 3,300 people have died in Sierra Leones cases since the beginning of October, the IOHM said, with an additional 1,000 cases reported daily.WHO has already received $1bn from the International Monetary Funds ($1.1bn) to help the country combat the outbreak.
It is the first time the organisation has received this funding, which has come in response to the Ebola crisis in the country.
In a statement, IOM chief executive Christine Lagarde said: “Our focus is to ensure that Sierra Leone continues to have the capacity and capacity to contain and control the outbreak, and that we are able to continue to provide medical care, protection and support to those who need it.”
