Google has launched a campaign to offer $2 for every $1 donated via its website, in a new fundraiser programme to fight the deadly Ebola virus in West Africa.

Users can donate from $10 to $1,000, with Google matching each dollar donated with an additional two.

The proceeds will be equally circulated among four charities including International Rescue Committee, Doctors Without Borders, Partners in Health and Save the Children.

Google CEO Larry Page said: "Today, Google is launching a public giving campaign to fight Ebola.

"For every dollar you give, Google will donate two dollars.

"In addition, we’re donating $10 million right away to support nonprofits such as InSTEDD, International Rescue Committee, Medecins Sans Frontieres, NetHope, Partners in Health, Save the Children and U.S. Fund for UNICEF.

"Separately, our family foundation will also be giving $15 million. Our hearts go out to everyone whose lives have been touched by this tragedy."

As of previous week, about 13,000 individuals have been infected with the virus, which has left 4,818 dead, mostly in Guinea, Liberia and Sierra Leone.

Prior to Google, Facebook founder Mark Zuckerberg promised to donate $25m, while Microsoft co-founder Paul Allen committed to contribute $100m for the campaign.
