The first comprehensive survey of global spending on neglected disease R&D, published in this week's PLoS Medicine, finds that just over $US 2.5 billion was invested into R&D of new products in 2007, with three diseases—HIV/AIDS, TB, and malaria—receiving nearly 80% of the total.
However, the survey finds that many neglected diseases, responsible for killing millions of people in developing countries, are significantly underfunded.
