World Bank announced Monday they will raise as much as $200 million to provide emergency funding for the African countries of Guinea, Sierra Leone and Liberia to aid in the battle against the Ebola virus outbreak.

The money will also be given to the World Health Organization, and will help support meical staff and in obtaining medical supplies, bank president Jim Yong Kim told BBC.

Kim said his time working with the WHO taught him that epidemics like this can happen any time and the world has the responsibility of coming together to help fight it and prevent it from occurring again.

The virus is contributing to the breakdown of "already weak health systems in the three countries," he told BBC. "I am very worried that many more lives are at risk unless we can stop this Ebola epidemic in its tracks."

While the contribution has not been approved yet as it awaits the confirmation from the Board of Directors, it is likely to go through this week.

The announcement came at the start of the first-ever U.S.-Africa Leaders summit in Washington, D.C., where discussions were slated to take place for three days about ways to strengthen diplomatic and economic ties between the U.S. and the nations of Africa.

The death toll from the Ebola outbreak in western Africa rose to 887 Monday, most of which were reported in Liberia, according to CBS. The World Health Organization said the deaths were a total from four nations including Nigeria, Sierra Leone and Guinea.

Nigeria is the newest on the list of countries affected by the outbreak, and has two cases so far.

Nigerian Health Minister Onyebuchi Chukwu told CBS that the second confirmed case is a doctor who helped treat a Liberian-American man who died on July 25.

The World Bank and International Monetary Fund told BBC the epidemic may affect Guinea's economic output this year.
