Neglected tropical diseases (NTDs) afflict more than 1.4 billion people, many of whom live on less than $1.25 a day. While there are effective ways to manage NTDs, policy-makers and funders have only recently begun to recognize the economic and public health importance of controlling NTDs. The IOM's Forum on Microbial Threats held a workshop September 21-22, 2010, to discuss the science of and policy surrounding NTDs.
