Microsoft founder and Billionaire philanthropist Bill Gates has addressed the World Economic Forum at Davos and pledged a further $750m (£479m) to a global fund to combat AIDS, tuberculosis and malaria.
"These are tough economic times, but that is no excuse for cutting aid to the world's poorest," said Gates.
The Gates Foundation Global Fund is a public-private partnership, which claims to save 100,000 lives a month. The Foundation has given $650m since its launch at Davos ten years ago.
The WEF's annual gathering of over 2,600 delegates includes world leaders, economists and business chiefs.
"By supporting the Global Fund, we can help to change the fortunes of the poorest countries in the world," said Mr Gates. "I can't think of more important work."
The Fund has provided medical treatment to 3.3 million people, detected and treated 8.2 million people with tuberculosis, and provided 230 million bed nets to families to prevent malaria.
