The organization's Director-General, Tedros Adhanom Ghebreyesus, has stressed that the gap is far from evenly distributed: the poorest nations have only a tenth of the health workers available in the richest ones.

The map of inequality is stark. Nearly 70% of that global shortfall is concentrated in the WHO's Africa and Eastern Mediterranean regions, according to data published by the WHO itself in 2025. The African continent illustrates the scale of the problem well: although its health workforce grew from 4.3 million in 2018 to 5.72 million in 2024, the region currently covers only 46% of the professionals it needs. The 2030 projection has been revised slightly downward, but remains alarming: from a forecast deficit of 6.1 million to 5.85 million.

Southeast Asia and the Pacific present another side of the same problem. Given its demographic weight, the WHO projects this region will account for the largest net shortage of health workers in absolute terms by 2030, even as the most severe challenges in relative terms remain in sub-Saharan Africa.

Behind these figures lies a structural cause the WHO itself identifies: chronic underinvestment in training. Health workforce training today accounts for just 2% of total global health spending, roughly $110 billion a year, a figure insufficient to meet the sector's needs.

The result is a quiet, planet-wide redistribution of medical talent: countries with strong health systems and established training capacity are emerging as key players in easing, through professional mobility, a shortage the WHO no longer describes as temporary but as a structural trend for the coming decade.
