At a meeting of nearly 1500 experts, donors, health ministers, and others in Uganda last month, participants endorsed a plan to address the shortages of health workers around the world and to reduce the migration of health professionals from developing countries to richer nations (http://www.who.int/workforcealliance/forum/2_declaration_final.pdf).
The World Health Organization (WHO) estimates that there is a global shortfall of more than 4 million health workers, one-quarter of whom are needed in sub-Saharan Africa alone.
