Global health and the role of universities in the twenty-first century.

A vast gap exists between knowledge, generation of knowledge, and the application of knowledge to the needs and benefit of the global population. In middle-income and lower-income countries, universities are becoming more engaged with the communities in which they are located to try to solve the difficult problems of poverty and poor health. Global collaborations and reform of medical education in the twenty-first century will help move universities out of cloistered academic settings and into the community to bring the changes needed to equitably meet the health needs of all.
