Global Health Infrastructure and Disparities

Global health infrastructure — hospitals, trained personnel, laboratories, cold-chain systems for vaccines and medicines, and health financing mechanisms — is distributed with striking geographic unevenness, and this unevenness is itself one of the strongest predictors of health outcomes worldwide. The World Health Organization's Global Health Workforce Statistics have long documented a severe shortfall concentrated in sub-Saharan Africa and parts of South Asia, and the WHO's 2016 Global Strategy on Human Resources for Health projected a global shortage of roughly 18 million health workers by 2030 if trends continued unaddressed, concentrated overwhelmingly in low- and lower-middle-income countries even though those countries carry a disproportionate share of the global disease burden. This mismatch is compounded by the "brain drain" phenomenon, in which physicians and nurses trained in lower-income countries emigrate to wealthier nations offering higher salaries and better working conditions — a pattern documented extensively for countries such as the Philippines, India, and several sub-Saharan African nations, and one the WHO addressed directly through its 2010 Global Code of Practice on the International Recruitment of Health Personnel, a voluntary framework intended to discourage active recruitment from countries facing the most severe workforce shortages.
