The world's largest chocolate companies are joining the fight against Ebola.

West Africa is where most of the world's cocoa beans are grown and the companies are concerned that the virus could disrupt supply of the raw material for chocolate. Already, wholesale cocoa prices have been soaring in recent weeks.

Nestlé, Hershey and Mars say they have already responded to a call from the World Cocoa Foundation, a non-profit that helps small cocoa farmers. The group plans to disclose Wednesday how much it has raised. Others in the group include Hershey (HSY), Godiva, Ghirardelli, General Mills (GIS) and Mondelez International (MDLZ).

Donations will go to the International Federation of Red Cross, the Red Crescent Societies, and Caritas, a charity affiliated with the Catholic Church.

Mars Chocolate -- maker of MilkyWay, Twix and M&Ms -- said it was "happy to support" the initiative.

West Africa produces 70% of the world's cocoa supply. The largest cocoa producer in the world is the Ivory Coast, which has so far avoided contamination. But there is concern that migrant workers may not be allowed into the country to help with this year's harvest. The Ivory Coast, also called Côte D'Ivoire, closed off its borders with Guinea and Liberia in August.
